Configuring Cisco UCS Server Pools and Policies

This chapter contains the following sections:

UUID Pools

A UUID pool is a collection of SMBIOS (Systems Management Built In Operating System) UUIDs (Universally Unique Identifiers) that are available to be assigned to servers. The first number of digits that constitute the prefix of the UUID are fixed. The remaining digits, the UUID suffix, are variable. A UUID pool ensures that these variable values are unique for each server associated with a service profile which uses that particular pool to avoid conflicts.

If you use UUID pools in service profiles, you do not have to manually configure the UUID of the server associated with the service profile.

Server Pools

A server pool contains a set of servers. These servers typically share the same characteristics. Those characteristics can be their location in the chassis, or an attribute such as server type, amount of memory, local storage, type of CPU, or local drive configuration. You can manually assign a server to a server pool, or use server pool policies and server pool policy qualifications to automate the assignment.

If your system implements multitenancy through organizations, you can designate one or more server pools to be used by a specific organization. For example, a pool that includes all servers with two CPUs could be assigned to the Marketing organization, while all servers with 64 GB memory could be assigned to the Finance organization.

A server pool can include servers from any chassis in the system. A given server can belong to multiple server pools.

Boot Policy

The Cisco UCS Manager enables you to create a boot policy for blade servers and rack servers.

The Cisco UCS Manager boot policy overrides the boot order in the BIOS setup menu and determines the following:

  • Selection of the boot device

  • Location from which the server boots

  • Order in which boot devices are invoked

For example, you can 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 can either create a named boot policy to associate with one or more service profiles, or create a boot policy for a specific service profile. A boot policy must be included 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, Cisco UCS Manager applies the default boot policy.


Note

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

You can also specify the following for the boot policy:

  • Local LUN name. The name specified is the logical name in the storage profile, not the deployed name. Specify only a primary name. Specifying a secondary name results in a configuration error.

  • Specific JBOD disk number for booting from JBOD disks.

  • Any LUN for backward compatibility; however, we do not recommend this. Other devices must not have bootable images to ensure a successful boot.


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.

Cisco recommends using 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 same operating system image. Therefore, the new server appears as the 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 (Logical Unit Number) on the device where the operating system image is located.


Note

SAN boot is not supported on Gen-3 Emulex adapters on Cisco UCS blade and rack servers.


Creating a SAN Boot Policy


Tip

We recommend that the boot order, in a boot policy, include either a local disk or a SAN LUN, but not both. It helps avoid the possibility of the server booting from the wrong storage type. 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 boots 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.


Before you begin

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.

Enforce vNIC/vHBA Name check box

If checked, a configuration error is displayed if one or more of the vNICs, vHBAs, or iSCSI vNICs listed in the Boot Order table matches the server configuration in the service profile.

If not checked, the policy uses the vNICs, vHBAs, or iSCSI vNICs (as appropriate for the boot option) if they exist, otherwise vNICs, vHBAs, or iSCSI vNICs with the lowest PCIe bus scan order is used.

Step 10

In the CIMC Mounted vMedia area, check one or both of the following options to select the vMedia device to add to the boot policy:

  • Add CIMC Mounted CD/DVD

  • Add CIMC Mounted HDD

Step 11

Click Submit.


Creating a vMedia Policy and vMounts

vMedia enables dynamic mapping of an external image file to the server’s CIMC. If a vMedia file is mapped as a CDD, then the image file presents itself as a CD-ROM image. vMedia can be referenced as a device in a Boot Policy, from which a server attempts to boot.

vMedia policies are bound to Service Profiles (SPs). Any given SP can have only one vMedia policy active at any given time. However, the policy can include one or more vMedia Mount.


Note

Changing the vMedia Policy for a service profile does not cause service profile reconfiguration, reboot, or service interruption.


Before you begin

Make sure that you have the required minimum version of Cisco UCS Manager, the BIOS, and CIMC. See Cisco UCS Director Compatibility Matrix.

      Note 

      If you use a hostname, configure the Cisco UCS Domain to use a DNS server. The DNS name can be used when an inband network is configured for that server.

    6. Absolute Remote Path—Enter the full path to the remote vMedia file.

      Note 

      If the selected protocol is CIFS, then use forward slashes in the path.

    7. Generate File Name from Service Profile Name—Choose one of the following options:

      • None—If you choose this option, enter a Remote File Name that the vMedia policy must use.

      • Service-Profile-Name—If you choose this option, the service profile name is used as the image name.

  3. Click Submit.

Step 11

Click Submit.


Creating a iSCSI Boot Policy

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

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 a 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 it 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.

For multipath configurations, a single iSCSI Qualified Name (IQN) is 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.

Before you begin

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

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

  • Verify that the operating system (OS) is iSCSI Boot Firmware Table (iBFT) compatible.
