Configuring Server-Related Policies

This chapter includes the following sections:

Configuring BIOS Settings

Server BIOS Settings

Cisco UCS provides two methods for making global modifications to the BIOS settings on servers in an Cisco UCS domain. You can create one or more BIOS policies that include a specific grouping of BIOS settings that match the needs of a server or set of servers, or you can use the default BIOS settings for a specific server platform.

Both the BIOS policy and the default BIOS settings for a server platform enable you to fine tune the BIOS settings for a server managed by Cisco UCS Manager.

Depending upon the needs of the data center, you can configure BIOS policies for some service profiles and use the BIOS defaults in other service profiles in the same Cisco UCS domain, or you can use only one of them. You can also use Cisco UCS Manager to view the actual BIOS settings on a server and determine whether they are meeting current needs.


Note


Cisco UCS Manager pushes BIOS configuration changes through a BIOS policy or default BIOS settings to the Cisco Integrated Management Controller (CIMC) buffer. These changes remain in the buffer and do not take effect until the server is rebooted.

We recommend that you verify the support for BIOS settings in the server that you want to configure. Some settings, such as Mirroring Mode and Sparing Mode for RAS Memory, are not supported by all Cisco UCS servers.


Main BIOS Settings

The following table lists the main server BIOS settings that you can configure through a BIOS policy or the default BIOS settings:

Name Description

Reboot on BIOS Settings Change

When the server is rebooted after you change one or more BIOS settings.

If you enable this setting, the server is rebooted according to the maintenance policy in the server's service profile. For example, if the maintenance policy requires user acknowledgment, the server is not rebooted and the BIOS changes are not applied until a user acknowledges the pending activity.

If you do not enable this setting, the BIOS changes are not applied until the next time the server is rebooted, whether as a result of another server configuration change or a manual reboot.

Quiet Boot

What the BIOS displays during Power On Self-Test (POST). This can be one of the following:

  • disabled—The BIOS displays all messages and Option ROM information during boot.
  • enabled—The BIOS displays the logo screen, but does not display any messages or Option ROM information during boot.
  • Platform Default—The BIOS uses the value for this attribute contained in the BIOS defaults for the server type and vendor.

Post Error Pause

What happens when the server encounters a critical error during POST. This can be one of the following:

  • disabled—The BIOS continues to attempt to boot the server.
  • enabled—The BIOS pauses the attempt to boot the server and opens the Error Manager when a critical error occurs during POST.

BIOS Policy

The BIOS policy is a policy that automates the configuration of BIOS settings for a server or group of servers. You can create global BIOS policies available to all servers in the root organization, or you can create BIOS policies in sub-organizations that are only available to that hierarchy.

To use a BIOS policy, do the following:

  1. Create the BIOS policy in Cisco UCS Manager.
  2. Assign the BIOS policy to one or more service profiles.
  3. Associate the service profile with a server.

During service profile association, Cisco UCS Manager modifies the BIOS settings on the server to match the configuration in the BIOS policy. If you do not create and assign a BIOS policy to a service profile, the server uses the default BIOS settings for that server platform.

Default BIOS Settings

Cisco UCS Manager includes a set of default BIOS settings for each type of server supported by Cisco UCS. The default BIOS settings are available only in the root organization and are global. Only one set of default BIOS settings can exist for each server platform supported by Cisco UCS. You can modify the default BIOS settings, but you cannot create an additional set of default BIOS settings.

Each set of default BIOS settings are designed for a particular type of supported server and are applied to all servers of that specific type which do not have a BIOS policy included in their service profiles.

Unless a Cisco UCS implementation has specific needs that are not met by the server-specific settings, we recommend that you use the default BIOS settings that are designed for each type of server in the Cisco UCS domain.

Cisco UCS Manager applies these server platform-specific BIOS settings as follows:

  • The service profile associated with a server does not include a BIOS policy.
  • The BIOS policy is configured with the platform-default option for a specific setting.

You can modify the default BIOS settings provided by Cisco UCS Manager. However, any changes to the default BIOS settings apply to all servers of that particular type or platform. If you want to modify the BIOS settings for only certain servers, we recommend that you use a BIOS policy.

Creating a BIOS Policy


Note


Cisco UCS Manager pushes BIOS configuration changes through a BIOS policy or default BIOS settings to the Cisco Integrated Management Controller (CIMC) buffer. These changes remain in the buffer and do not take effect until the server is rebooted.

We recommend that you verify the support for BIOS settings in the server that you want to configure. Some settings, such as Mirroring Mode and Sparing Mode for RAS Memory, are not supported by all Cisco UCS servers.


Procedure
    Step 1   In the Navigation pane, click the Servers tab.
    Step 2   On the Servers tab, expand Servers > Policies.
    Step 3   Expand the node for the organization where you want to create the policy.

        Configuring IPMI Access Profiles

        IPMI Access Profile

        This policy allows you to determine whether IPMI commands can be sent directly to the server, using the IP address. For example, you can send commands to retrieve sensor data from the CIMC. This policy defines the IPMI access, including a username and password that can be authenticated locally on the server, and whether the access is read-only or read-write.

        You must include this policy in a service profile and that service profile must be associated with a server for it to take effect.

        Creating an IPMI Access Profile

        Before You Begin

        An IPMI profile requires that one or more of the following resources already exist in the system:

        • Username with appropriate permissions that can be authenticated by the operating system of the server
        • Password for the username
        • Permissions associated with the username
        Procedure
          Step 1   In the Navigation pane, click the Servers tab.
          Step 2   On the Servers tab, expand Servers > Policies.
          Step 3   Expand the node for the organization where you want to create the policy.

          If the system does not include multitenancy, expand the root node.

          Step 4   Right-click IPMI Profiles and select Create IPMI Profiles.
          Step 5   In the Create IPMI Profile dialog box:
          1. Enter a unique name and description for the profile.
          2. Click OK.
          Step 6   In the IPMI Profile Users area of the navigator, click +.
          Step 7   In the User Properties dialog box:
          1. Complete the following fields:
            Name Description

            Name field

            The username to associate with this IPMI profile.

            Enter 1 to 16 alphanumeric characters. You can also use @ (at sign), _ (underscore), and - (hyphen). You cannot change this name once the profile has been saved.

            Password field

            The password associated with this username.

            Enter 1 to 20 standard ASCII characters, except for = (equal sign), $ (dollar sign), and | (vertical bar).

            Confirm Password field

            The password a second time for confirmation purposes.

            Role field

            The user role. This can be one of the following:

            • Admin
            • Read Only
          2. Click OK.
          Step 8   Repeat Steps 6 and 7 to add another user.
          Step 9   Click OK to return to the IPMI profiles in the Work pane.

          What to Do Next

          Include the IPMI profile in a service profile and/or template.

          Deleting an IPMI Access Profile

          Procedure
            Step 1   In the Navigation pane, click the Servers tab.
            Step 2   In the Servers tab, expand Servers > Policies > Organization_Name
            Step 3   Expand the IPMI Profiles node.
            Step 4   Right-click the profile you want to delete and select Delete.
            Step 5   If the Cisco UCS Manager GUI displays a confirmation dialog box, click Yes.

            Configuring Local Disk Configuration Policies

            Local Disk Configuration Policy

            This policy configures any optional SAS local drives that have been installed on a server through the onboard RAID controller of the local drive. This policy enables you to set a local disk mode for all servers that are associated with a service profile that includes the local disk configuration policy.

            The local disk modes include the following:

            • No Local Storage—For a diskless server or a SAN only configuration. If you select this option, you cannot associate any service profile which uses this policy with a server that has a local disk.
            • RAID 0 Striped—Data is striped across all disks in the array, providing fast throughput. There is no data redundancy, and all data is lost if any disk fails.
            • RAID 1 Mirrored—Data is written to two disks, providing complete data redundancy if one disk fails. The maximum array size is equal to the available space on the smaller of the two drives.
            • Any Configuration—For a server configuration that carries forward the local disk configuration without any changes.
            • No RAID—For a server configuration that removes the RAID and leaves the disk MBR and payload unaltered.
            • RAID 5 Striped Parity—Data is striped across all disks in the array. Part of the capacity of each disk stores parity information that can be used to reconstruct data if a disk fails. RAID 5 provides good data throughput for applications with high read request rates.
            • RAID 6 Striped Dual Parity—Data is striped across all disks in the array and two parity disks are used to provide protection against the failure of up to two physical disks. In each row of data blocks, two sets of parity data are stored.
            • RAID10 Mirrored and Striped— RAID 10 uses mirrored pairs of disks to provide complete data redundancy and high throughput rates.

            You must include this policy in a service profile, and that service profile must be associated with a server for the policy to take effect.

            Guidelines for all Local Disk Configuration Policies

            Before you create a local disk configuration policy, consider the following guidelines:

            No Mixed HDDs and SSDs

            Do not include HDDs and SSDs in a single server or RAID configuration.

            Do Not Assign a Service Profile with the Default Local Disk Configuration Policy from a B200 M1 or M2 to a B200 M3

            Due to the differences in the RAID/JBOD support provided by the storage controllers of B200 M1 and M2 servers and those of the B200 M3 server, you cannot assign or re-assign a service profile that includes the default local disk configuration policy from a B200M1 or M2 server to a B200 M3 server. The default local disk configuration policy includes those with Any Configuration or JBOD configuration.

            Impact of Upgrade from a Release Prior to Release 1.3(1i)

            An upgrade from an earlier Cisco UCS firmware release to release 1.3(1i) or higher has the following impact on the Protect Configuration property of the local disk configuration policy the first time servers are associated with service profiles after the upgrade:

            Unassociated Servers

            After you upgrade the Cisco UCS domain, the initial server association proceeds without configuration errors whether or not the local disk configuration policy matches the server hardware. Even if you enable the Protect Configuration property, Cisco UCS does not protect the user data on the server if there are configuration mismatches between the local disk configuration policy on the previous service profile and the policy in the new service profile.


            Note


            If you enable the Protect Configuration property and the local disk configuration policy encounters mismatches between the previous service profile and the new service profile, all subsequent service profile associations with the server are blocked.


            Associated Servers

            Any servers that are already associated with service profiles do not reboot after the upgrade. Cisco UCS Manager does not report any configuration errors if there is a mismatch between the local disk configuration policy and the server hardware.

            When a service profile is disassociated from a server and a new service profile associated, the setting for the Protect Configuration property in the new service profile takes precedence and overwrites the setting in the previous service profile.

            Guidelines for Local Disk Configuration Policies Configured for RAID

            No Mixed HDDs and SSDs

            Do not include HDDs and SSDs in a single RAID configuration.

            Do Not Use the Any Configuration Mode on Servers with MegaRAID Storage Controllers

            If a blade server or rack-mount server in a Cisco UCS domain includes a MegaRAID storage controller, do not configure the local disk configuration policy in the service profile for that server with the Any Configuration mode. If you use this mode for servers with a MegaRAID storage controller, the installer for the operating system cannot detect any local storage on the server.

            If you want to install an operating system on local storage on a server with a MegaRAID storage controller, you must configure the local disk configuration policy with a mode that creates a RAID LUN (RAID volume) on the server.

            Server May Not Boot After RAID1 Cluster Migration if Any Configuration Mode Specified in Service Profile

            After RAID1 clusters are migrated, you need to associate a service profile with the server. If the local disk configuration policy in the service profile is configured with Any Configuration mode rather than RAID1, the RAID LUN remains in "inactive" state during and after association. As a result, the server cannot boot.

            To avoid this issue, ensure that the service profile you associate with the server contains the identical local disk configuration policy as the original service profile before the migration and does not include the Any Configuration mode.

            Configure RAID Settings in Local Disk Configuration Policy for Servers with MegaRAID Storage Controllers

            If a blade server or integrated rack-mount server has a MegaRAID controller, you must configure RAID settings for the drives in the Local Disk Configuration policy included in the service profile for that server.

            If you do not configure your RAID LUNs before installing the OS, disk discovery failures might occur during the installation and you might see error messages such as “No Device Found.”

            Do Not Use JBOD Mode on Servers with MegaRAID Storage Controllers

            Do not configure or use JBOD mode or JBOD operations on any blade server or integrated rack-mount server with a MegaRAID storage controllers. JBOD mode and operations are not intended for nor are they fully functional on these servers.

            Maximum of One RAID Volume and One RAID Controller in Integrated Rack-Mount Servers

            A rack-mount server that has been integrated with Cisco UCS Manager can have a maximum of one RAID volume irrespective of how many hard drives are present on the server.

            All the local hard drives in an integrated rack-mount server must be connected to only one RAID Controller. Integration with Cisco UCS Manager does not support the connection of local hard drives to multiple RAID Controllers in a single rack-mount server. We therefore recommend that you request a single RAID Controller configuration when you order rack-mount servers to be integrated with Cisco UCS Manager.

            In addition, do not use third party tools to create multiple RAID LUNs on rack-mount servers. Cisco UCS Manager does not support that configuration.

            Maximum of One RAID Volume and One RAID Controller in Blade Servers

            A blade server can have a maximum of one RAID volume irrespective of how many drives are present in the server. All the local hard drives must be connected to only one RAID controller. For example, a B200 M3 server has an LSI controller and an Intel Patsburg controller, but only the LSI controller can be used as a RAID controller.

            In addition, do not use third party tools to create multiple RAID LUNs on blade servers. Cisco UCS Manager does not support that configuration.

            Number of Disks Selected in Mirrored RAID Should Not Exceed Two

            If the number of disks selected in the Mirrored RAID exceed two, RAID 1 is created as a RAID 10 LUN. This issue can occur with the Cisco UCS B440 M1 and B440 M2 servers.

            B420 M3 Server Does Not Support All Configuration Modes

            The B420 M3 server does not support the following configuration modes in a local disk configuration policy:

            • No RAID
            • RAID 6 Striped Dual Parity

            In addition, the B420 M3 does not support JBOD modes or operations.

            Creating a Local Disk Configuration Policy

            Procedure
              Step 1   In the Navigation pane, click the Servers tab.
              Step 2   On the Servers tab, expand Servers > Policies.
              Step 3   Expand the node for the organization where you want to create the policy.

              If the system does not include multitenancy, expand the root node.

              Step 4   Right-click Local Disk Config Policies and choose Create Local Disk Configuration Policy.
              Step 5   In the Create Local Disk Configuration Policy dialog box, complete the following fields:
              Name Description

              Name field

              The name of the policy.

              This name can be between 1 and 16 alphanumeric characters. You cannot use spaces or any special characters other than - (hyphen), _ (underscore), : (colon), and . (period), and you cannot change this name after the object has been saved.

              Description field

              A description of the policy. We recommend that you include information about where and when the policy should be used.

              Enter up to 256 characters. You can use any characters or spaces except ^ (carat), \ (backslash), > (greater than), < (less than), ' (single quote), " (double quote), ` (accent mark), or = (equal sign).

              Mode drop-down list

              This can be one of the following local disk policy modes:

              • No Local Storage—For a diskless server or a SAN only configuration. If you select this option, you cannot associate any service profile which uses this policy with a server that has a local disk.
              • RAID 0 Striped—Data is striped across all disks in the array, providing fast throughput. There is no data redundancy, and all data is lost if any disk fails.
              • RAID 1 Mirrored—Data is written to two disks, providing complete data redundancy if one disk fails. The maximum array size is equal to the available space on the smaller of the two drives.
              • Any Configuration—For a server configuration that carries forward the local disk configuration without any changes.
              • No RAID—For a server configuration that removes the RAID and leaves the disk MBR and payload unaltered.
              • RAID 5 Striped Parity—Data is striped across all disks in the array. Part of the capacity of each disk stores parity information that can be used to reconstruct data if a disk fails. RAID 5 provides good data throughput for applications with high read request rates.
              • RAID 6 Striped Dual Parity—Data is striped across all disks in the array and two parity disks are used to provide protection against the failure of up to two physical disks. In each row of data blocks, two sets of parity data are stored.
              • RAID10 Mirrored and Striped— RAID 10 uses mirrored pairs of disks to provide complete data redundancy and high throughput rates.
              Note   

              If you choose No RAID and you apply this policy to a server that already has an operating system with RAID storage configured, the system does not remove the disk contents. Therefore, there may be no visible differences on the server after you apply the No RAID mode. This can lead to a mismatch between the RAID configuration in the policy and the actual disk configuration shown in the Inventory > Storage tab for the server.

              To make sure that any previous RAID configuration information is removed from a disk, apply a scrub policy that removes all disk information after you apply the No RAID configuration mode.

              Protect Configuration check box

              If checked, the server retains the configuration in the local disk configuration policy even if the server is disassociated from the service profile.

              Caution   

              Protect Configuration becomes non-functional if one or more disks in the server are defective or faulty.

              This property is checked by default.

              When a service profile is disassociated from a server and a new service profile associated, the setting for the Protect Configuration property in the new service profile takes precedence and overwrites the setting in the previous service profile.

              Note   

              If you disassociate the server from a service profile with this option enabled and then associate it with a new service profile that includes a local disk configuration policy with different properties, the server returns a configuration mismatch error and the association fails.

              Step 6   Click OK.

              Changing a Local Disk Configuration Policy

              This procedure describes how to change a local disk configuration policy from an associated service profile. You can also change a local disk configuration policy from the Policies node of the Servers tab.

                  Configuring Scrub Policies

                  Scrub Policy

                  This policy determines what happens to local data and to the BIOS settings on a server during the discovery process and when the server is disassociated from a service profile. Depending upon how you configure a scrub policy, the following can occur at those times:

                  Disk Scrub

                  One of the following occurs to the data on any local drives on disassociation:

                  • If enabled, destroys all data on any local drives
                  • If disabled, preserves all data on any local drives, including local storage configuration
                  BIOS Settings Scrub

                  One of the following occurs to the BIOS settings when a service profile containing the scrub policy is disassociated from a server:

                  • If enabled, erases all BIOS settings for the server and and resets them to the BIOS defaults for that server type and vendor
                  • If disabled, preserves the existing BIOS settings on the server

                  Creating a Scrub Policy

                  Procedure
                    Step 1   In the Navigation pane, click the Servers tab.
                    Step 2   On the Servers tab, expand Servers > Policies.
                    Step 3   Expand the node for the organization where you want to create the policy.

                    Step 5   In the Create Scrub Policy wizard, complete the following fields:
                    Name Description

                    Name field

                    The name of the policy.

                    This name can be between 1 and 16 alphanumeric characters. You cannot use spaces or any special characters other than - (hyphen), _ (underscore), : (colon), and . (period), and you cannot change this name after the object has been saved.

                    Description field

                    A description of the policy. We recommend that you include information about where and when the policy should be used.

                    Enter up to 256 characters. You can use any characters or spaces except ^ (carat), \ (backslash), > (greater than), < (less than), ' (single quote), " (double quote), ` (accent mark), or = (equal sign).

                    Disk Scrub field

                    If this field is set to Yes, when a service profile containing this scrub policy is disassociated from a server, all data on the server local drives is completely erased. If this field is set to No, the data on the local drives is preserved, including all local storage configuration.

                    BIOS Settings Scrub field

                    If the field is set to Yes, when a service profile containing this scrub policy is disassociated from a server, the BIOS settings for that server are erased and reset to the defaults for that server type and vendor. If this field is set to No, the BIOS settings are preserved.

                    Step 6   Click OK.

                    Deleting a Scrub Policy

                      Configuring Serial over LAN Policies

                      Serial over LAN Policy

                      This policy sets the configuration for the serial over LAN connection for all servers associated with service profiles that use the policy. By default, the serial over LAN connection is disabled.

                      If you implement a serial over LAN policy, we recommend that you also create an IPMI profile.

                      You must include this policy in a service profile and that service profile must be associated with a server for it to take effect.

                      Creating a Serial over LAN Policy

                      Procedure
                        Step 1   In the Navigation pane, click the Servers tab.
                        Step 2   On the Servers tab, expand Servers > Policies.
                        Step 3   Expand the node for the organization where you want to create the policy.

                        If the system does not include multitenancy, expand the root node.

                        Step 4   Right-click Serial over LAN Policies and select Create Serial over LAN Policy.
                        Step 5   In the Create Serial over LAN Policy wizard, complete the following fields:
                        Name Description

                        Name field

                        The name of the policy.

                        This name can be between 1 and 16 alphanumeric characters. You cannot use spaces or any special characters other than - (hyphen), _ (underscore), : (colon), and . (period), and you cannot change this name after the object has been saved.

                          Configuring Server Autoconfiguration Policies

                          Server Autoconfiguration Policy

                          Cisco UCS Manager uses this policy to determine how to configure a new server. If you create a server autoconfiguration policy, the following occurs when a new server starts:

                          1. The qualification in the server autoconfiguration policy is executed against the server.
                          2. If the server meets the required qualifications, the server is associated with a service profile created from the service profile template configured in the server autoconfiguration policy. The name of that service profile is based on the name given to the server by Cisco UCS Manager.
                          3. The service profile is assigned to the organization configured in the server autoconfiguration policy.

                          Creating an Autoconfiguration Policy

                          Before You Begin

                          This policy requires that one or more of the following resources already exist in the system:

                          • Server pool policy qualifications
                          • Service profile template
                          • Organizations, if a system implements multi-tenancy
                          Procedure

                            Name field

                            The name of the policy.

                            This name can be between 1 and 16 alphanumeric characters. You cannot use spaces or any special characters other than - (hyphen), _ (underscore), : (colon), and . (period), and you cannot change this name after the object has been saved.

                            Description field

                            A description of the policy. We recommend that you include information about where and when the policy should be used.

                            Enter up to 256 characters. You can use any characters or spaces except ^ (carat), \ (backslash), > (greater than), < (less than), ' (single quote), " (double quote), ` (accent mark), or = (equal sign).

                            Qualification drop-down list

                            The server pool policy qualification associated with this auto-configuration policy.

                            If a new server is discovered that matches the criteria specified in the server pool policy qualification, Cisco UCS automatically creates a service profile based on the service profile template selected in the Service Profile Template Name drop-down list and associates the newly created service profile with the server.

                            Org drop-down list

                            The organization associated with this autoconfiguration policy.

                            If Cisco UCS automatically creates a service profile to associate with a server, it places the service profile under the organization selected in this field.

                            Service Profile Template Name drop-down list

                            The service profile template associated with this policy.

                            Step 7   Click OK.

                            Deleting an Autoconfiguration Policy

                              Configuring Server Discovery Policies

                              Server Discovery Policy

                              This discovery policy determines how the system reacts when you add a new server. If you create a server discovery policy, you can control whether the system conducts a deep discovery when a server is added to a chassis, or whether a user must first acknowledge the new server. By default, the system conducts a full discovery.

                              If you create a server discovery policy, the following occurs when a new server starts:

                              1. The qualification in the server discovery policy is executed against the server.
                              2. If the server meets the required qualifications, Cisco UCS Manager applies the following to the server:
                                • Depending upon the option selected for the action, either discovers the new server immediately or waits for a user to acknowledge the new server
                                • Applies the scrub policy to the server

                              Creating a Server Discovery Policy

                              Before You Begin

                              If you plan to associate this policy with a server pool, create server pool policy qualifications.

                              Procedure
                                Step 1   In the Navigation pane, click the Equipment tab.

                                  Configuring Server Inheritance Policies

                                  Server Inheritance Policy

                                  This policy is invoked during the server discovery process to create a service profile for the server. All service profiles created from this policy use the values burned into the blade at manufacture. The policy performs the following:

                                  • Analyzes the inventory of the server
                                  • If configured, assigns the server to the selected organization
                                  • Creates a service profile for the server with the identity burned into the server at manufacture

                                  You cannot migrate a service profile created with this policy to another server.

                                  Creating a Server Inheritance Policy

                                  A blade server or rack-mount server with a VIC adapter, such as the Cisco UCS M81KR Virtual Interface Card, does not have server identity values burned into the server hardware at manufacture. As a result, the identity of the adapter must be derived from default pools. If the default pools do not include sufficient entries for one to be assigned to the server, service profile association fails with a configuration error.

                                  Procedure
                                    Step 1   In the Navigation pane, click the Equipment tab.

                                    Qualification drop-down list

                                    If you want to associate this policy with one or more specific server pools, choose the server pool qualification policy that identifies these pools from the drop-down list.

                                    Org drop-down list

                                    If you want to associate an organization with this policy, or if you want to change the current association, choose the desired organization from the drop-down list.

                                      Server Pool Policy

                                      This policy is invoked during the server discovery process. It determines what happens if server pool policy qualifications match a server to the target pool specified in the policy.

                                      If a server qualifies for more than one pool and those pools have server pool policies, the server is added to all those pools.

                                          Configuring Server Pool Policy Qualifications

                                          Server Pool Policy Qualifications

                                          This policy qualifies servers based on the inventory of a server conducted during the discovery process. The qualifications are individual rules that you configure in the policy to determine whether a server meets the selection criteria. For example, you can create a rule that specifies the minimum memory capacity for servers in a data center pool.

                                          Qualifications are used in other policies to place servers, not just by the server pool policies. For example, if a server meets the criteria in a qualification policy, it can be added to one or more server pools or have a service profile automatically associated with it.

                                          You can use the server pool policy qualifications to qualify servers according to the following criteria:

                                          • Adapter type
                                          • Chassis location
                                          • Memory type and configuration
                                          • Power group
                                          • CPU cores, type, and configuration
                                          • Storage configuration and capacity
                                          • Server model

                                          Depending upon the implementation, you may configure several policies with server pool policy qualifications including the following:

                                          • Autoconfiguration policy
                                          • Chassis discovery policy
                                          • Server discovery policy
                                          • Server inheritance policy
                                          • Server pool policy

                                                Configuring vNIC/vHBA Placement Policies

                                                vNIC/vHBA Placement Policies

                                                vNIC/vHBA placement policies are used to determine what types of vNICs or vHBAs can be assigned to the physical adapters on a server. Each vNIC/vHBA placement policy contains four virtual network interface connections (vCons) that are virtual representations of the physical adapters. When a vNIC/vHBA placement policy is assigned to a service profile, and the service profile is associated with a server, the vCons in the vNIC/vHBA placement policy are assigned to the physical adapters.

                                                If you do not include a vNIC/vHBA placement policy in the service profile or you use the default configuration for a server with two adapters, Cisco UCS Manager defaults to the All configuration and equally distributes the vNICs and vHBAs between the adapters.

                                                You can use this policy to assign vNICs or vHBAs to either of the two vCons. Cisco UCS Manager uses the vCon assignment to determine how to assign the vNICs and vHBAs to the physical adapter during service profile association.

                                                • All—All configured vNICs and vHBAs can be assigned to the vCon, whether they are explicitly assigned to it, unassigned, or dynamic.
                                                • Assigned Only—vNICs and vHBAs must be explicitly assigned to the vCon. You can assign them explicitly through the service profile or the properties of the vNIC or vHBA.
                                                • Exclude Dynamic—Dynamic vNICs and vHBAs cannot be assigned to the vCon. The vCon can be used for all static vNICs and vHBAs, whether they are unassigned or explicitly assigned to it.
                                                • Exclude Unassigned—Unassigned vNICs and vHBAs cannot be assigned to the vCon. The vCon can be used for dynamic vNICs and vHBAs and for static vNICs and vHBAs that are explicitly assigned to it.

                                                vCon to Adapter Placement

                                                Cisco UCS Manager maps every vCon in a service profile to a physical adapter on the server. How that mapping occurs and how the vCons are assigned to a specific adapter in a server with two adapters depends upon the type of server. You must consider this placement when you configure the vNIC/vHBA placement policy to assign vNICs and vHBAs to vCons.


                                                Note


                                                vCon to adapter placement is not dependent upon the PCIE slot number of the adapter. The adapter numbers used for the purpose of vCon placement are not the PCIE slot numbers of the adapters, but the ID assigned to them during server discovery.


                                                vCon to Adapter Placement for N20-B6620-2 and N20-B6625-2 Blade Servers

                                                In these blade servers, the adapters are numbered left to right, but vCons are numbered right to left. If the server has a single adapter, all vCons are assigned to that adapter. However, if the server has two adapters, the vCons are assigned to the adapters in reverse order, as follows:

                                                • Adapter1 is assigned vCon2 and vCon4
                                                • Adapter2 is assigned vCon1 and vCon3

                                                vCon to Adapter Placement for All Other Supported Servers

                                                For all other servers supported by Cisco UCS, the vCon assignment depends upon the number of adapters in the server, as follows:

                                                vNIC/vHBA to vCon Assignment

                                                Cisco UCS Manager provides two options for assigning vNICs and vHBAs to vCons through the vNIC/vHBA placement policy: explicit assignment and implicit assignment.

                                                Explicit Assignment of vNICs and vHBAs

                                                With explicit assignment, you specify the vCon and, therefore, the adapter to which a vNIC or vHBA is assigned. Use this assignment option when you need to determine how the vNICs and vHBAs are distributed between the adapters on a server.

                                                To configure a vCon and the associated vNICs and vHBAs for explicit assignment, do the following:
                                                • Set the vCon configuration to any of the available options. You can configure the vCons through a vNIC/vHBA placement policy or in the service profile associated with the server. If a vCon is configured for All, you can still explicitly assign a vNIC or vHBA to that vCon.
                                                • Assign the vNICs and vHBAs to a vCon. You can make this assignment through the Virtual Host Interface Placement properties of the vNIC or vHBA or in the service profile associated with the server.

                                                If you attempt to assign a vNIC or vHBA to a vCon that is not configured for that type of vNIC or vHBA, Cisco UCS Manager displays a message box to advise you of the configuration error.

                                                During service profile association, Cisco UCS Manager validates the configured placement of the vNICs and vHBAs against the number and capabilities of the physical adapters in the server before assigning the vNICs and vHBAs according to the configuration in the policy. Load distribution is based upon the explicit assignments to the vCons and adapters configured in this policy.

                                                If the adapters do not support the assignment of one or more vNICs or vHBAs, Cisco UCS Manager raises a fault against the service profile.


                                                Note


                                                vCon to adapter assignment occurs in a round-robin order. This order means that vNICs are placed on the adapters in the following order: vcon-1, vcon-3, vcon-2, vcon-4. As a result, under the following circumstances, the PCIE order of vNICs can be different than the explicit assignment configured in Cisco UCS Manager:

                                                • In a server with two adapters when vNICs are explicitly assigned to all four vCons.
                                                • When a service profile that includes explicit assignment is migrated from a server with a higher number of adapters to one with a lower number of adapters.

                                                Implicit Assignment of vNICs and vHBAs

                                                With implicit assignment, Cisco UCS Manager determines the vCon and, therefore, the adapter to which a vNIC or vHBA is assigned according to the capability of the adapter. Use this assignment option if the adaptor to which a vNIC or vHBA is assigned is not important to your system configuration.

                                                To configure a vCon for implicit assignment, do the following:

                                                • Set the vCon configuration to All, Exclude Dynamic, or Exclude Unassigned. You can configure the vCons through a vNIC/vHBA placement policy or in the service profile associated with the server.
                                                • Do not set the vCon configuration to Exclude Assigned. Implicit assignment cannot be performed with this setting.
                                                • Do not assign any vNICs or vHBAs to a vCon.

                                                During service profile association, Cisco UCS Manager verifies the number and capabilities of the physical adapters in the server and assigns the vNICs and vHBAs accordingly. Load distribution is based upon the capabilities of the adapters, and placement of the vNICs and vHBAs is performed according to the actual order determined by the system. For example, if one adapter can accommodate more vNICs than another, that adapter is assigned more vNICs.

                                                If the adapters cannot support the number of vNICs and vHBAs configured for that server, Cisco UCS Manager raises a fault against the service profile.

                                                Implicit Assignment of vNICs in a Mixed Adapter Environment

                                                The implicit assignment of vNICs functions differently for a server that has mixed adapters, as follows:

                                                • A dual slot server that has one VIC adapter and one non-VIC adapter, which have different capabilities. For example, a server that contains a Cisco UCS M81KR Virtual Interface Card and a Cisco UCS CNA M71KR-E adapter.
                                                • A configuration that includes both dynamic vNICs and static vNICs.

                                                When you assign vNICs implicitly for a dual slot server that has one VIC adapter and non-VIC adapter, Cisco UCS Manager typically assigns one vNIC to each adapter. The remaining vNICs are assigned according to the relative capabilities of the adapters. The following are examples of the relative capabilities of some of the supported adapters:

                                                • Cisco UCS M81KR Virtual Interface Card (128 vNICs) and Cisco UCS CNA M71KR-E Adapter (2 vNICs) have a 64:1 capability ratio
                                                • Cisco UCS M81KR Virtual Interface Card and Cisco UCS CNA M72KR-E have a 64:1 capability ratio
                                                • Cisco UCS CNA M72KR-E and Cisco UCS CNA M72KR-E have a 1:1 capability ratio
                                                • Cisco UCS M82-8P Virtual Interface Card and Cisco UCS CNA M71KR-E adapter have a 128:1 capability ratio
                                                • Cisco UCS M82-8P Virtual Interface Card and Cisco UCS M81KR Virtual Interface Card have a 2:1 capability ratio.

                                                For example, a Cisco UCS M81KR Virtual Interface Card can handle up to 128 vNICs, while a Cisco UCS CNA M71KR-E can only handle 2 vNICs. This difference gives those adapters a 64:1 ratio. If a dual slot blade server has one of each and you choose to allow implicit assignment of vNICs by Cisco UCS Manager, the load balancing ratio assigns the majority of the vNICs to the Cisco UCS M81KR Virtual Interface Card, as follows:

                                                Total Number of vNICs vNICs Assigned to Cisco UCS M81KR Virtual Interface Card vNICs Assigned to Cisco UCS CNA M71KR-E Adapter

                                                Note


                                                Exceptions to this implicit assignment occur if you configure the vNICs for fabric failover and if you configure dynamic vNICs for the server.


                                                For a configuration that includes vNIC fabric failover where one adapter does not support vNIC failover, Cisco UCS Manager implicitly assigns all vNICs which have fabric failover enabled to the adapter that supports them. If the configuration only includes vNICs that are configured for fabric failover, no vNICs are implicitly assigned to the adapter which does not support them. If some vNICs are configured for fabric failover and some are not, Cisco UCS Manager assigns all failover vNICs to the adapter which supports them and a minimum of one non-failover vNIC to the adapter which does not support them, according to the ratio above.

                                                For a configuration that includes dynamic vNICs, the same implicit assignment would occur. Cisco UCS Manager assigns all dynamic vNICs to the adapter that supports them. However, with a combination of dynamic vNICs and static vNICs, at least one static vNIC is assigned to the adapter that does not support dynamic vNICs.

                                                Creating a vNIC/vHBA Placement Policy

                                                Procedure
                                                  Step 1   In the Navigation pane, click the Servers tab.
                                                  Step 2   On the Servers tab, expand Servers > Policies.
                                                  Step 3   Expand the node for the organization where you want to create the policy.

                                                  If the system does not include multitenancy, expand the root node.

                                                  Step 4   Right-click vNIC/vHBA Placement Policies and choose Create Placement Policy.
                                                  Step 5   In the Create Placement Policy dialog box, do the following:
                                                  1. In the Name field, enter a unique name for the placement policy.

                                                    This name can be between 1 and 16 alphanumeric characters. You cannot use spaces or any special characters other than - (hyphen), _ (underscore), : (colon), and . (period), and you cannot change this name after the object has been saved.

                                                  2. In the Selection Preference column for each Virtual Slot, choose one of the following from the drop-down list:
                                                    • All—All configured vNICs and vHBAs can be assigned to the vCon, whether they are explicitly assigned to it, unassigned, or dynamic.
                                                    • Assigned Only—vNICs and vHBAs must be explicitly assigned to the vCon. You can assign them explicitly through the service profile or the properties of the vNIC or vHBA.
                                                    • Exclude Dynamic—Dynamic vNICs and vHBAs cannot be assigned to the vCon. The vCon can be used for all static vNICs and vHBAs, whether they are unassigned or explicitly assigned to it.
                                                    • Exclude Unassigned—Unassigned vNICs and vHBAs cannot be assigned to the vCon. The vCon can be used for dynamic vNICs and vHBAs and for static vNICs and vHBAs that are explicitly assigned to it.
                                                  3. Click OK.

                                                  Deleting a vNIC/vHBA Placement Policy

                                                  Procedure
                                                    Step 1   In the Navigation pane, click the Servers tab.
                                                    Step 2   On the Servers tab, expand Servers > Policies > Organization_Name.
                                                    Step 3   Expand the vNIC/vHBA Placement Policies node.
                                                    Step 4   Right-click the policy you want to delete and choose Delete.
                                                    Step 5   If the Cisco UCS Manager GUI displays a confirmation dialog box, click Yes.

                                                    Explicitly Assigning a vNIC to a vCon

                                                    Before You Begin

                                                    Configure the vCons through a vNIC/vHBA placement policy or in the service profile with one of the following values:

                                                    • Assigned Only
                                                    • Exclude Dynamic
                                                    • Exclude Unassigned

                                                    If a vCon is configured for All, you can still explicitly assign a vNIC or vHBA to that vCon. However, you have less control with this configuration.

                                                    Procedure
                                                      Step 1   In the Navigation pane, click the Servers tab.
                                                      Step 2   On the Servers tab, expand Servers > Service Profiles.
                                                      Step 3   Expand the node for the organization which contains the service profile whose vNICs you want to explicitly assign to a vCon.

                                                      If the system does not include multitenancy, expand the root node.

                                                      Step 4   Expand Service_Profile_Name > vNICs.
                                                      Step 5   Click on the vNIC that you want to explicitly assign to a vCon.
                                                      Step 6   In the Work pane, click the General tab.
                                                      Step 7   In the Virtual Host Interface Placement section, complete the following fields:
                                                      Name Description

                                                      Desired Placement drop-down list

                                                      The user-specified virtual network interface connection (vCon) placement for the vNIC. This can be one of the following:

                                                      • Any—Allows Cisco UCS Manager to determine the vCon to which the vNIC is assigned.
                                                      • 1—Explicitly assigns the vNIC to vCon1.
                                                      • 2—Explicitly assigns the vNIC to vCon2.
                                                      • 3—Explicitly assigns the vNIC to vCon3.
                                                      • 4—Explicitly assigns the vNIC to vCon4.

                                                      Actual Assignment field

                                                      The actual vCon assignment of the vNIC on the server.

                                                      If you attempt to assign a vNIC to a vCon that is not configured for that type of vNIC, Cisco UCS Manager displays a message box to advise you of the configuration error. You must either assign the vNIC to another vCon or change the vCon configuration in the service profile.

                                                      Step 8   In the Order section, complete the following fields:
                                                      Name Description

                                                      Desired Order field

                                                      The user-specified PCI order for the vNIC.

                                                      Enter an integer between 0 and 128. You cannot create more than 128 vNICs for a server.

                                                      Actual Order field

                                                      The actual PCI order of the vNIC on the server.

                                                      Explicitly Assigning a vHBA to a vCon

                                                      Before You Begin

                                                      Configure the vCons through a vNIC/vHBA placement policy or in the service profile with one of the following values:

                                                      • Assigned Only
                                                      • Exclude Dynamic
                                                      • Exclude Unassigned

                                                      If a vCon is configured for All, you can still explicitly assign a vNIC or vHBA to that vCon. However, you have less control with this configuration.

                                                      Procedure
                                                        Step 1   In the Navigation pane, click the Servers tab.
                                                        Step 2   On the Servers tab, expand Servers > Service Profiles.
                                                        Step 3   Expand the node for the organization which contains the service profile whose vHBAs you want to explicitly assign to a vCon.

                                                        If the system does not include multitenancy, expand the root node.

                                                        Step 4   Expand Service_Profile_Name > vHBAs.
                                                        Step 5   Click on the vHBA that you want to explicitly assign to a vCon.
                                                        Step 6   In the Work pane, click the General tab.
                                                        Step 7   In the Virtual Host Interface Placement section, complete the following fields:
                                                        Name Description

                                                        Desired Placement field

                                                        The user-specified virtual network interface connection (vCon) placement for the vHBA. This can be one of the following:

                                                        • Any—Allows Cisco UCS Manager to determine the vCon to which the vHBA is assigned.
                                                        • 1—Explicitly assigns the vHBA to vCon1.
                                                        • 2—Explicitly assigns the vHBA to vCon2.
                                                        • 3—Explicitly assigns the vHBA to vCon3.
                                                        • 4—Explicitly assigns the vHBA to vCon4.

                                                        Actual Assignment field

                                                        The actual vCon assignment of the vHBA on the server.

                                                        If you attempt to assign a vHBA to a vCon that is not configured for that type of vHBA, Cisco UCS Manager displays a message box to advise you of the configuration error. You must either assign the vHBA to another vCon or change the vCon configuration in the service profile.

                                                        Step 8   In the Order section, complete the following fields:
                                                        Name Description

                                                        Desired Order field

                                                        Enter an integer between 0 and 128. You cannot create more than 128 vHBAs for a server.

                                                        Actual Order field

                                                        The actual PCI order of the vHBA on the server.
