Configuring Server Boot

This chapter includes the following sections:

Boot Policy

The boot policy determines the following:

  • Configuration of the boot device

  • Location from which the server boots

  • Order in which boot devices are invoked

For example, you can choose to have associated servers boot from a local device, such as a local disk or CD-ROM (VMedia), or you can select a SAN boot or a LAN (PXE) boot.

You must include this policy in a service profile, and that service profile must be associated with a server for it to take effect. If you do not include a boot policy in a service profile, the server uses the default settings in the BIOS to determine the boot order.


Note

Changes to a boot policy might be propagated to all servers created with an updating service profile template that includes that boot policy. Reassociation of the service profile with the server to rewrite the boot order information in the BIOS is automatically triggered.

Creating a Boot Policy

You can also create a local boot policy that is restricted to a service profile or service profile template. However, we recommend that you create a global boot policy that can be included in multiple service profiles or service profile templates.

Before You Begin

If you are creating a boot policy that boots the server from a SAN LUN and you require reliable SAN boot operations, you must first remove all local disks from servers associated with a service profile that includes the boot policy.

Procedure
     Command or ActionPurpose
    Step 1UCS-A# scope org org-name  

    Enters organization mode for the specified organization. To enter the root organization mode, type / as the org-name .

     
    Step 2UCS-A /org # create boot-policy policy-name [purpose {operational | utility}]  

    Creates a boot policy with the specified policy name, and enters organization boot policy mode.

    When you create the boot policy, specify the operational option. This ensures that the server boots from the operating system installed on the server. The utility options is reserved and should only be used if instructed to do so by a Cisco representative.

     
    Step 3UCS-A /org/boot-policy # set descr description   (Optional)

    Provides a description for the boot policy.

    Note   

    If your description includes spaces, special characters, or punctuation, you must begin and end your description with quotation marks. The quotation marks do not appear in the description field of any show command output.

     
    Step 4UCS-A /org/boot-policy # set reboot-on-update {no | yes}  

    Specifies whether the servers using this boot policy are automatically rebooted after you make changes to the boot order.

     
    Step 5UCS-A /org/boot-policy # set enforce-vnic-name {no | yes}  

    If you choose yes, Cisco UCS Manager uses any vNICs or vHBAs defined in the Boot Order.

    If you choose no, Cisco UCS Manager uses the priority specified in the vNIC or vHBA.

     
    Step 6UCS-A /org/boot-policy # commit-buffer  

    Commits the transaction to the system configuration.

     

    The following example creates a boot policy named boot-policy-LAN, provides a description for the boot policy, specifies that servers using this policy will not be automatically rebooted when the boot order is changed, and commits the transaction: 

    UCS-A# scope org /
UCS-A /org* # create boot-policy boot-policy-LAN purpose operational
UCS-A /org/boot-policy* # set descr "Boot policy that boots from the LAN."
UCS-A /org/boot-policy* # set reboot-on-update no
UCS-A /org/boot-policy* # commit-buffer
UCS-A /org/boot-policy #
    What to Do Next

    Configure one or more of the following boot options for the boot policy and set their boot order:

    • LAN Boot —Boots from a centralized provisioning server. It is frequently used to install operating systems on a server from that server.

      If you choose the LAN Boot option, continue to Configuring a LAN Boot for a Boot Policy.

    • Storage Boot — Boots from an operating system image on the SAN. You can specify a primary and a secondary SAN boot. If the primary boot fails, the server attempts to boot from the secondary.

      We recommend that you use a SAN boot, because it offers the most service profile mobility within the system. If you boot from the SAN, when you move a service profile from one server to another, the new server boots from exactly the same operating system image. Therefore, the new server appears to be exactly the same server to the network.

      If you choose the Storage Boot option, continue to Configuring a SAN Boot for a Boot Policy.

    • Virtual Media Boot —Mimics the insertion of a physical CD into a server. It is typically used to manually install operating systems on a server.

      If you choose the Virtual Media boot option, continue to Configuring a Virtual Media Boot for a Boot Policy.


    Tip

    If you configure a local disk and a SAN LUN for the boot order storage type and the operating system or logical volume manager (LVM) is configured incorrectly, the server might boot from the local disk rather than the SAN LUN.

    For example, on a server with Red Hat Linux installed, where the LVM is configured with default LV names and the boot order is configured with a SAN LUN and a local disk, Linux reports that there are two LVs with the same name and boots from the LV with the lowest SCSI ID, which could be the local disk.

    Include the boot policy in a service profile and/or template.

    SAN Boot

    You can configure a boot policy to boot one or more servers from an operating system image on the SAN. The boot policy can include a primary and a secondary SAN boot. If the primary boot fails, the server attempts to boot from the secondary.

    We recommend that you use a SAN boot, because it offers the most service profile mobility within the system. If you boot from the SAN when you move a service profile from one server to another, the new server boots from the exact same operating system image. Therefore, the new server appears to be the exact same server to the network.

    To use a SAN boot, ensure that the following is configured:

    • The Cisco UCS domain must be able to communicate with the SAN storage device that hosts the operating system image.

    • A boot target LUN on the device where the operating system image is located.

    Configuring a SAN Boot for a Boot Policy


    Tip

    If you configure a local disk and a SAN LUN for the boot order storage type and the operating system or logical volume manager (LVM) is configured incorrectly, the server might boot from the local disk rather than the SAN LUN.

    For example, on a server with Red Hat Linux installed, where the LVM is configured with default LV names and the boot order is configured with a SAN LUN and a local disk, Linux reports that there are two LVs with the same name and boots from the LV with the lowest SCSI ID, which could be the local disk.

    This procedure continues directly from Creating a Boot Policy.

    Before You Begin

    Create a boot policy to contain the SAN boot configuration.


    Note

    If you are creating a boot policy that boots the server from a SAN LUN and you require reliable SAN boot operations, we recommend that you first remove all local disks from servers associated with a service profile that includes the boot policy.

    Procedure
       Command or ActionPurpose
      Step 1UCS-A# scope org org-name  

      Enters organization mode for the specified organization. To enter the root organization mode, type / as the org-name .

       
      Step 2UCS-A /org # scope boot-policy policy-name  

      Enters organization boot policy mode for the specified boot policy.

       
      Step 3UCS-A /org/boot-policy # create storage  

      Creates a SAN boot for the boot policy and enters organization boot policy storage mode.

       
      Step 4UCS-A /org/boot-policy/storage # set order {1 | 2 | 3 | 4}  

      Sets the boot order for the SAN boot.

       
      Step 5UCS-A /org/boot-policy/storage # create san-image {primary | secondary}  

      Creates a SAN image location, and if the san-image option is specified, enters organization boot policy storage SAN image mode.

      When using the enhanced boot order on Cisco UCS M3 servers, the boot order that you define is used. For standard boot mode, the use of the terms primary or secondary boot devices does not imply a boot order. The effective order of boot devices within the same device class is determined by PCIe bus scan order.

      Include the boot policy in a service profile and/or template.

      iSCSI Boot

      iSCSI boot enables a server to boot its operating system from an iSCSI target machine located remotely over a network.

      iSCSI boot is supported on the following Cisco UCS hardware:

      • Cisco UCS server blades that have the Cisco UCS M51KR-B Broadcom BCM57711 network adapter and use the default MAC address provided by Broadcom.

      • Cisco UCS M81KR Virtual Interface Card

      • Cisco UCS VIC-1240 Virtual Interface Card

      • Cisco UCS VIC-1280 Virtual Interface Card

      There are prerequisites that must be met before you configure iSCSI boot. For a list of these prerequisites, see iSCSI Boot Guidelines and Prerequisites.

      For a high-level procedure for implementing iSCSI boot, see Configuring iSCSI Boot.

      iSCSI Boot Process

      Cisco UCS Manager uses the iSCSI vNIC and iSCSI boot information created for the service profile in the association process to program the adapter, located on the server. After the adapter is programmed, the server reboots with the latest service profile values. After the power on self-test (POST), the adapter attempts to initialize using these service profile values. If the adapter can use the values and log in to its specified target, the adapter initializes and posts an iSCSI Boot Firmware Table (iBFT) to the host memory and a valid bootable LUN to the system BIOS. The iBFT that is posted to the host memory contains the initiator and target configuration that is programmed on the primary iSCSI VNIC.


      Note

      Previously, the host would see only one of the boot paths configured, depending on which path completed the LUN discovery first, and would boot from that path. Now, when there are two iSCSI boot vNICs configured, the host will see both of the boot paths. So for multipath configurations, a single IQN needs to be configured on both the boot vNICs If there are different IQNs configured on the boot vNICs on a host, the host will boot with the IQN that is configured on the boot vNIC with the lower PCI order.

      The next step, which is the installation of the operating system (OS), requires an OS that is iBFT capable. During installation of the OS, the OS installer scans the host memory for the iBFT table and uses the information in the iBFT to discover the boot device and create an iSCSI path to the target LUN. In some OS's a NIC driver is required to complete this path. If this step is successful, the OS installer finds the iSCSI target LUN on which to install the OS.


      Note

      The iBFT works at the OS installation software level and might not work with HBA mode (also known as TCP offload). Whether iBFT works with HBA mode depends on the OS capabilities during installation. Also, for a server that includes a Cisco UCS M51KR-B Broadcom BCM57711 adapter, the iBFT normally works at a maximum transmission unit (MTU) size of 1500, regardless of the MTU jumbo configuration. If the OS supports HBA mode, you might need to set HBA mode, dual-fabric support, and jumbo MTU size after the iSCSI installation process.

      iSCSI Boot Guidelines and Prerequisites

      These guidelines and prerequisites must be met before configuring iSCSI boot:

      • After the iSCSI boot policies have been created, a user with ls-compute privileges can include them in a service profile or service profile template. However, a user with only ls-compute privileges cannot create iSCSI boot policies.

      • To set up iSCSI boot from a Windows 2008 server where the second vNIC (failover vNIC) must boot from an iSCSI LUN, consult Microsoft Knowledge Base Article 976042. Microsoft has a known issue where Windows might fail to boot from an iSCSI drive or cause a bugcheck error if the networking hardware is changed. To work around this issue, follow the resolution recommended by Microsoft.

      • The storage array must be licensed for iSCSI boot and the array side LUN masking must be properly configured.

      • Two IP addresses must be determined, one for each iSCSI initiator. If possible, the IP addresses should be on the same subnet as the storage array. The IP addresses are assigned statically or dynamically using the Dynamic Host Configuration Protocol (DHCP).

      • You cannot configure boot parameters in the Global boot policy. Instead, after configuring boot parameters, you need to include the boot policy in the appropriate service profile.

      • The operating system (OS) must be iSCSI Boot Firmware Table (iBFT) compatible.

      • For Cisco UCS M51KR-B Broadcom BCM57711 network adapters:

        • Servers that use iSCSI boot must contain the Cisco UCS M51KR-B Broadcom BCM57711 network adapter. For information on installing or replacing an adapter card, see the Cisco UCS B250 Extended Memory Blade Server Installation and Service Note. The service note is accessible from the Cisco UCS B-Series Servers Documentation Roadmap at http:/​/​www.cisco.com/​go/​unifiedcomputing/​b-series-doc.

        • Set the MAC addresses on the iSCSI device.

        • If you are using the DHCP Vendor ID (Option 43), configure the MAC address of an iSCSI device in /etc/dhcpd.conf.

        • HBA mode (also known as TCP offload) and the boot to target setting are supported. However, only Windows OS supports HBA mode during installation.

        • Before installing the OS, disable the boot to target setting in the iSCSI adapter policy, then after installing the OS, reenable the boot to target setting.

          Note

          Each time you change an adapter policy setting, the adapter reboots to apply the new setting.

        • When installing the OS on the iSCSI target, the iSCSI target must be ordered before the device where the OS image resides. For example, if you are installing the OS on the iSCSI target from a CD, the boot order should be the iSCSI target and then the CD.

        • After the server has been iSCSI booted, do not modify the Initiator Name, Target name, LUN, iSCSI device IP, or Netmask/gateway using the Broadcom tool.

        • Do not interrupt the POST (power on self-test) process or the Cisco UCS M51KR-B Broadcom BCM57711 network adapter will fail to initialize.

      • For Cisco UCS M81KR Virtual Interface Card and Cisco UCS VIC-1240 Virtual Interface Card:

        • Do not set MAC addresses on the iSCSI device.

        • HBA mode and the boot to target setting are not supported.

        • When installing the OS on the iSCSI target, the iSCSI target must be ordered after the device where the OS image resides. For example, if you are installing the OS on the iSCSI target from a CD, the boot order should be the CD and then the iSCSI target.

        • If you are using the DHCP Vendor ID (Option 43), the MAC address of the overlay vNIC needs to be configured in /etc/dhcpd.conf.

        • After the server has been iSCSI booted, do not modify the IP details of the overlay vNIC.

      • The VMware ESX/ESXi operating system does not support storing a core dump file to an iSCSI boot target LUN. Dump files must be written to a local disk.

      Initiator IQN Configuration

      Cisco UCS uses the following rules to determine the initiator IQN for an adapter iSCSI vNIC at the time a service profile is associated with a physical server:

      • An initiator IQN at the service profile level and at the iSCSI vNIC level cannot be used together in a service profile.

      • If an initiator IQN is specified at the service profile level, all of the adaptor iSCSI vNICs are configured to use the same initiator IQN, except in the case of DHCP Option 43, where the initiator IQN is set to empty on the adapter iSCSI vNIC.

      • When an initiator IQN is set at the iSCSI vNIC level, the initiator IQN at the service profile level is removed, if one is present.

      • If there are two iSCSI vNIC in a service profile and only one of them has the initiator IQN set, the second one is configured with the default IQN pool. You can change this configuration later. The only exception is if DHCP Option 43 is configured. In this case, the initiator IQN on the second iSCSI vNIC is removed during service profile association.

      Enabling MPIO on Windows


      Note

      If you change the networking hardware, Windows may fail to boot from an iSCSI drive. For more information, see Microsoft support Article ID: 976042.

      Before You Begin

      The server on which you enable MPIO must have a Cisco VIC driver.

      If there are multiple paths configured to the boot LUN, only one path should be enabled when the LUN is installed.

      Procedure
        Step 1   In the service profile associated with the server, configure the primary iSCSI vNIC.

        For more information, see Creating an iSCSI vNIC in a Service Profile.

        Step 2   Using the primary iSCSI vNIC, install the Windows operating system on the iSCSI target LUN.
        Step 3   After Windows installation is completed, enable MPIO on the host.
        Step 4   In the service profile associated with the server, add the secondary iSCSI vNIC to the boot policy.

        For more information, see Creating an iSCSI Boot Policy.

        Configuring iSCSI Boot

        When you configure an adapter or blade in Cisco UCS to iSCSI boot from a LUN target, you need to complete all of the following steps.

        Procedure
           Command or ActionPurpose
          Step 1Configure the iSCSI boot adapter policy.  (Optional)

          For more information, see Creating an iSCSI Adapter Policy

           
          Step 2Configure the authentication profiles to be used by the initiator and target.  (Optional)

          For more information, see Creating an Authentication Profile

           
          Step 3If you plan to configure the iSCSI initiator to use an IP address from a pool of IP addresses, add a block of IP addresses to the iSCSI initiator pool.  (Optional)

          For more information, see Adding a Block of IP Addresses to the Initiator Pool

           
          Step 4Create a boot policy that can be used in any service profile. Alternatively, you can create a local boot policy only for the specific service policy. However, we recommend that you create a boot policy that can be shared with multiple service profiles. 

          For more information about creating a boot policy that can be used in any service profile, see Creating an iSCSI Boot Policy.

           
          Step 5If you created a boot policy that can be used in any service profile, you need to assign it to the service profile. Otherwise, proceed to the next step. 

          For more information, see Creating a Service Profile Template.

           
          Step 6Configure an Ethernet vNIC in a service profile.  

          The Ethernet vNIC is used as the overlay vNIC for the iSCSI device. For more information, see Configuring a vNIC for a Service Profile.

           
          Step 7Create an iSCSI vNIC in a service profile. 

          For more information, see Creating an iSCSI vNIC in a Service Profile

           
          Step 8Set the iSCSI initiator to boot using a static IP Address, an IP address from an IP pool, or DHCP. 

          See either Creating an iSCSI Initiator that Boots Using a Static IP Address, Creating an iSCSI Initiator that Boots Using an IP Address from an IP Pool, or Creating an iSCSI Initiator that Boots Using DHCP.

           
          Step 9Create an iSCSI static or auto target. 

          For more information, see either Creating an iSCSI Static Target or Creating an iSCSI Auto Target.

           
          Step 10Associate the service profile with a server. 

          For more information, see Associating a Service Profile with a Blade Server or Server Pool.

           
          Step 11Verify the iSCSI boot operation. 

          For more information, see Verifying iSCSI Boot

           
          Step 12Install the OS on the server. 
          For more information, see one of the following guides:

            Step 4UCS-A /org/iscsi-policy # set iscsi-protocol-item connection-timeout timeout-secs  

            The number of seconds to wait until Cisco UCS assumes that the initial login has failed and the iSCSI adapter is unavailable.

            Enter an integer between 0 and 255. If you enter 0, Cisco UCS uses the value set in the adapter firmware (default: 15 seconds).

             
            Step 5UCS-A /org/iscsi-policy # set iscsi-protocol-item dhcp-timeout timeout-secs  

            The number of seconds to wait before the initiator assumes that the DHCP server is unavailable.

            Enter an integer between 60 and 300 (default: 60 seconds).

             
            Step 6UCS-A /org/iscsi-policy # set iscsi-protocol-item lun-busy-retry-count num  

            The number of times to retry the connection in case of a failure during iSCSI LUN discovery.

            Enter an integer between 0 and 60. If you enter 0, Cisco UCS uses the value set in the adapter firmware (default: 15 seconds).

             
            Step 7UCS-A /org/iscsi-policy # set iscsi-protocol-item tcp-time-stamp {no | yes}  

            Specifies whether to apply a TCP timestamp. With this setting, transmitted packets are given a time stamp of when the packet was sent so that the packet's round-trip time can be calculated, when needed. This setting applies only to Cisco UCS M51KR-B Broadcom BCM57711 adapters.

             
            Step 8UCS-A /org/iscsi-policy # set iscsi-protocol-item hbamode {no | yes}  

            Specifies whether to enable HBA mode.

            This option should only be enabled for servers with the Cisco UCS NIC M51KR-B adapter running the Windows operating system.

             
            Step 9UCS-A /org/iscsi-policy # set iscsi-protocol-item boottotarget {no | yes}  

            Specifies whether to boot from the iSCSI target.

            This option only applies to servers with the Cisco UCS NIC M51KR-B adapter. It should be disabled until you have installed an operating system on the server.

             
            Step 10UCS-A /org/iscsi-policy # commit-buffer

              Creating an Authentication Profile

              If you use authentication for iSCSI boot, you need to create an authentication profile for both the initiator and target.

              Procedure
                 Command or ActionPurpose
                Step 1UCS-A# scope org org-name  

                Enters organization mode for the specified organization. To enter the root organization mode, type / as the org-name .

                 
                Step 2UCS-A /org # create auth-profile profile-name  

                Creates an authentication profile with the specified name. The name can be up to 16 alphanumeric characters.

                 
                Step 3UCS-A /org/auth-profile* # set user-id id-name  

                Creates a log in for authentication.

                 
                Step 4UCS-A /org/auth-profile* # set password 

                Creates a password for authentication.

                 
                Step 5UCS-A /org/auth-profile* # commit-buffer  

                Commits the transaction to the system configuration.

                 
                Step 6UCS-A /org/auth-profile* # exit  

                Exits the current mode.

                 
                Step 7Repeat steps 2 through 6 to create an authentication profile for the target.   

                The following example shows how to create an authentication profile for an initiator and target and commit the transaction:

                UCS-A# scope org
UCS-A /org # create auth-profile InitAuth 
UCS-A /org/auth-profile* # set user-id init 
UCS-A /org/auth-profile* # set  password
Enter a password:
Confirm the password:
UCS-A /org/auth-profile* # commit-buffer 
UCS-A /org/auth-profile # exit
UCS-A /org # create auth-profile TargetAuth

                  Adding a Block of IP Addresses to the Initiator Pool

                  You can create a group of IP addresses to be used for iSCSI boot. Cisco UCS Manager reserves the block of IP addresses you specify.

                  The IP pool must not contain any IP addresses that have been assigned as static IP addresses for a server or service profile.

                  Procedure
                     Command or ActionPurpose
                    Step 1UCS-A# scope org org-name 

                    Enters organization mode for the specified organization. To enter the root organization mode, enter / as the org-name.

                     
                    Step 2UCS-A /org# scope ip-pool iscsi-initiator-pool 

                    Enters the mode to specify an iSCSI initiator pool.

                     
                    Step 3UCS-A /org/ip-pool # set descr description   (Optional)

                    Provides a description for the IP pool.

                    Note   

                    If your description includes spaces, special characters, or punctuation, you must begin and end your description with quotation marks. The quotation marks will not appear in the description field of any show command output.

                     
                    Step 4UCS-A /org/ip-pool # set assignmentorder {default | sequential} 

                    This can be one of the following:

                    • default—Cisco UCS Manager selects a random identity from the pool.

                    • sequential—Cisco UCS Manager selects the lowest available identity from the pool.

                     
                    Step 5UCS-A /org/ip-pool# create block from_ip_address to_ip_address default_gateway subnet_mask 

                    Creates a block of IP addresses for the iSCSI initiator.

                      Creating an iSCSI Boot Policy

                      You can add up to two iSCSI vNICs per boot policy. One vNIC acts as the primary iSCSI boot source, and the other acts as the secondary iSCSI boot source.

                      Procedure
                         Command or ActionPurpose
                        Step 1UCS-A# scope org org-name  

                        Enters organization mode for the specified organization. To enter the root organization mode, type / as the org-name .

                         
                        Step 2UCS-A /org # create boot-policy policy-name [purpose {operational | utility}]  

                        Creates a boot policy with the specified policy name, and enters organization boot policy mode.

                        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.

                        When you create the boot policy, specify the operational option. This ensures that the server boots from the operating system installed on the server. The utility options is reserved and should only be used if instructed to do so by a Cisco representative.

                         
                        Step 3UCS-A /org/boot-policy # set descr description   (Optional)

                        Provides a description for the boot policy.

                        Note   

                        If your description includes spaces, special characters, or punctuation, you must begin and end your description with quotation marks. The quotation marks do not appear in the description field of any show command output.

                         
                        Step 4UCS-A /org/boot-policy # set enforce-vnic-name {no | yes}   (Optional)

                        If you choose yes, Cisco UCS Manager reports whether the device name specified in the boot policy matches what is specified in the service profile.

                        If you choose no, Cisco UCS Manager uses any vNIC, vHBA, or iSCSI device from the service profile and does not report whether the device name specified in the boot policy matches what is specified in the service profile.

                         
                        Step 5UCS-A /org/boot-policy # set reboot-on-update {no | yes}  

                        Specifies whether the servers using this boot policy are automatically rebooted after you make changes to the boot order.

                        In the Cisco UCS Manager GUI, if the Reboot on Boot Order Change check box is checked for a boot policy, and if CD-ROM or Floppy is the last device in the boot order, deleting or adding the device does not directly affect the boot order and the server does not reboot.

                         
                        Step 6UCS-A /org/boot-policy # create iscsi  

                        Adds an iSCSI boot to the boot policy.

                         
                        Step 7UCS-A /org/boot-policy/iscsi # create path {primary | secondary}  

                        Specifies the primary and secondary paths that Cisco UCS Manager uses to reach the iSCSI target .With iSCSI boot, you set up two paths. Cisco UCS Manager uses the primary path first, and if that fails, then it uses the secondary path.

                         
                        Step 8UCS-A /org/boot-policy/iscsi/path # create iscsivnicname iscsi-vnic-name  

                        Creates an iSCSI vNIC.

                         
                        Step 9UCS-A /org/boot-policy/iscsi/path # exit  

                        Exits iSCSI path mode.

                         
                        Step 10UCS-A /org/boot-policy/iscsi/path # set order order-num  

                        Specifies the order for the iSCSI boot in the boot order.

                         
                        Step 11Repeat steps 8-10 to create secondary iSCSI vNICs.  (Optional) 
                        Step 12UCS-A /org/boot-policy/iscsi # commit-buffer  

                        Commits the transaction to the system configuration.

                         

                        The following example shows how to create an iSCSI boot policy named iscsi-boot-policy-LAN, provide a description for the boot policy, specify that servers using this policy are not automatically rebooted when the boot order is changed, set the boot order for iSCSI boot to 2, create an iSCSI boot and associate it with a vNIC called iscsienic1, and commit the transaction: 

                        UCS-A# scope org /
UCS-A /org* # create boot-policy iscsi-boot-policy-LAN purpose operational

                        What to Do Next

                        Include the boot policy in a service profile and/or template.

                        After a server is associated with a service profile that includes this boot policy, you can verify the actual boot order in the Boot Order Details area on the General tab for the server.

                                            IQN Pools

                                            An IQN pool is a collection of iSCSI Qualified Names (IQNs) for use as initiator identifiers by iSCSI vNICs in a Cisco UCS domain.

                                            IQN pool members are of the form prefix:suffix:number, where you can specify the prefix, suffix, and a block (range) of numbers.

                                            An IQN pool can contain more than one IQN block, with different number ranges and different suffixes, but sharing the same prefix.

                                            Creating an IQN Pool


                                            Note

                                            In most cases, the maximum IQN size (prefix + suffix + additional characters) is 223 characters. When using the Cisco UCS NIC M51KR-B adapter, you must limit the IQN size to 128 characters.

                                            Procedure
                                               Command or ActionPurpose

                                              Step 2UCS-A /org # create iqn-pool pool-name  

                                              Creates an IQN pool with the specified pool name and enters organization IQN pool mode.

                                              This name can be between 1 and 32 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.

                                               
                                              Step 3UCS-A /org/iqn-pool # set iqn-prefix prefix  

                                              Specifies the prefix for the IQN block members. Unless limited by the adapter card, the prefix can contain up to 150 characters.

                                              Provides a description for the IQN pool. Enter up to 256 characters.

                                              Note   

                                              If your description includes spaces, special characters, or punctuation, you must begin and end your description with quotation marks. The quotation marks will not appear in the description field of any show command output.

                                              This can be one of the following:

                                              • default—Cisco UCS Manager selects a random identity from the pool.

                                              • sequential—Cisco UCS Manager selects the lowest available identity from the pool.

                                               
                                              Step 6UCS-A /org/iqn-pool # create block suffix from to

                                                If you delete an address block from a pool, Cisco UCS Manager does not reallocate any addresses in that block that have been assigned to vNICs or vHBAs. All assigned addresses from a deleted block remain with the vNIC or vHBA to which they are assigned until one of the following occurs:

                                                • The associated service profiles are deleted.

                                                • The vNIC or vHBA to which the address is assigned is deleted.

                                                • The vNIC or vHBA is assigned to a different pool.

                                                        What to Do Next

                                                        To configure a second iSCSI device, repeat the steps for creating an iSCSI vNIC, initiator, and target.

                                                        Deleting an iSCSI Static Target

                                                        You can delete an iSCSI static target. However, you must have at least one iSCSI static target remaining after you delete one. Therefore, you must have two iSCSI static targets in order to delete one of them.


                                                        Note

                                                        If you have two iSCSI targets and you delete the first priority target, the second priority target becomes the first priority target, although the Cisco UCS Manager still shows it as the second priority target.

                                                          These prerequisites must be met before creating iSCSI auto target:

                                                          • You have already created an iSCSI vNIC in a service profile.

                                                          • You have considered the prerequisites for the VIC that you are using. For more information, see iSCSI Boot Guidelines and Prerequisites

                                                            You can delete an auto target only if you have a static target set.

                                                              Use the KVM console to view the boot up messages as the adapter is booting. For information on how to access the KVM console, see the Starting the KVM Console chapter.

                                                              This step can only be performed using the Cisco UCS Manager GUI. For more information, see the Starting the KVM Console chapter in the UCS Manager GUI Configuration Guide.

                                                              You can configure a boot policy to boot one or more servers from a centralized provisioning server on the LAN. A LAN (or PXE) boot is frequently used to install operating systems on a server from that LAN server.

                                                              You can add more than one type of boot device to a LAN boot policy. For example, you could add a local disk or virtual media boot as a secondary boot device.

                                                                Include the boot policy in a service profile and/or template.

                                                                Local Disk Boot

                                                                If a server has a local drive or bootable USB device, you can configure a boot policy to boot the server from that device with a local disk boot policy.


                                                                Note

                                                                Cisco UCS Manager does not differentiate between the types of local boot devices. If an operating system has been installed on more than one local drive or on an internal USB drive (eUSB), you cannot specify which of these devices the server should use as the boot drive.

                                                                Configuring a Local Disk Boot for a Boot Policy

                                                                You can also create a local boot policy that is restricted to a service profile or service profile template. However, we recommend that you create a global boot policy that can be included in multiple service profiles or service profile templates.

                                                                You can add more than one type of boot device to a boot policy. For example, you could add a virtual media boot as a secondary boot device.

                                                                  When using the enhanced boot order on Cisco UCS M3 servers, the boot order that you define is used. For standard boot mode, the use of the terms primary or secondary boot devices does not imply a boot order. The effective order of boot devices within the same device class is determined by PCIe bus scan order.

                                                                  Include the boot policy in a service profile and/or template.

                                                                  Virtual Media Boot

                                                                  You can configure a boot policy to boot one or more servers from a virtual media device that is accessible from the server. A virtual media device mimics the insertion of a physical CD-ROM disk (read-only) or floppy disk (read-write) into a server. This type of server boot is typically used to manually install operating systems on a server.

                                                                  Configuring a Virtual Media Boot for a Boot Policy

                                                                  Virtual Media requires the USB to be enabled. If you modify the BIOS settings that affect the USB functionality, you also affect the Virtual Media. Therefore, we recommend that you leave the following USB BIOS defaults for best performance:
