Important Guidelines for Cisco UCS Domain Management from UCS Central

Cisco recommends the following guidelines for managing Cisco UCS domains from Cisco UCS Central:

  • Cisco recommends that you always register Cisco UCS domains using Cisco UCS Central's Fully Qualified Domain Name (FQDN). If domains are registered with FQDN, any change in the Cisco UCS Central IP address is transparent to the domain.

    • Cisco UCS Central does not support changing Cisco UCS Central's IP address if a Cisco UCS domain is registered with a Cisco UCS Central IP address. For more information, see the Changing a Cisco UCS Central IP Address section in the Cisco UCS Central Installation and Upgrade Guide.

  • Before you upgrade Cisco UCS Central, it is recommended that you do a full state backup and take a VM snapshot.

  • You can migrate a Cisco UCS Central instance to support Data Center migration or disaster recovery scenarios. For more information about migrating a Cisco UCS Central instance, see the Cisco UCS Central Instance Migration section in the Cisco UCS Central Installation and Upgrade Guide.

  • Unregistering a registered Cisco UCS domain in a production system has serious implications. Do not unregister a Cisco UCS domain unless you choose to permanently not manage it again from Cisco UCS Central. For more information about registering and unregistering a Cisco UCS Domain from Cisco UCS Central, see the Cisco UCS Domains and Cisco UCS Central section in the Cisco UCS Central Installation and Upgrade Guide.

    When you unregister any registered Cisco UCS domain from Cisco UCS Central:

    • You can no longer manage the service profiles, policies, and other configuration for the Cisco UCS domain from Cisco UCS Central.

    • All global service profiles and policies become local and continue to operate as local entities. When you re-register the domain, the service profiles, and policies remain local.


    Important

    • Cisco UCS Central does not support High Availability (HA) for new installations. Cisco recommends that you install Cisco UCS Central in Standalone mode in a single virtual machine, and leverage the High Availability capabilities of the Hypervisor.

    • Upgrading Cisco UCS Central release 2.0(1d) or 2.0(1e) to 2.0(1k) could fail due to CSCvt12270. Cisco recommends that you first upgrade to Cisco UCS Central 2.0(1j) and then upgrade to 2.0(1k). For more information about this defect, see Open Caveats in release 2.0(1k).



    Caution

    Cisco recommends that you contact Cisco Technical Support if you want to unregister any registered Cisco UCS Domain in a production system.


See Related Documentation on Cisco.com for current information on Cisco UCS Central.

Support for Cisco HyperFlex Systems

Cisco UCS Central only supports inventory and monitoring of Cisco HyperFlex server nodes connected to a Cisco UCS Fabric Interconnect running a supported version of Cisco UCS Manager. The Cisco HX Data Platform Installer OVA currently creates and manages all required policy and service profiles locally via Cisco UCS Manager APIs and does not support global policies and service profiles. The Globalization feature of Cisco UCS Central 2.0 is not supported for Cisco HyperFlex Systems. Cisco recommends that you do not manually configure global service profiles and policies in Cisco UCS Central for Cisco HyperFlex as the upgrade functionality and procedures that are part of the Cisco HX Data Platform Installer will not work with any custom global configuration manually created through Cisco UCS Central.

When registering a Cisco UCS domain immediately after installation, you may see one of the following issues:

  • After installing Cisco UCS Central on RHEL 7.2 KVM, domain registration fails.

  • After installing Cisco UCS Central on VMware using the ISO image, domain registration may fail due to a time sync issue between Cisco UCS Manager and Cisco UCS Central.

If this issue occurs, regenerate the certificate manually from the CLI in Cisco UCS Central using the following commands:

# connect policy-mgr
# scope org
# scope device-profile
# scope security
# scope keyring default
# set regenerate yes
# commit-buffer

Excluding components from the host firmware package policy is supported in Cisco UCS Manager release 2.2.7 and above. When excluding components, you should be aware of the following:

  • The global-default host firmware package policy includes all components, but if you create a new custom host firmware package policy, the local disk component is automatically excluded.

  • Host firmware package policies created in Cisco UCS Central 1.3 or previous do not support excluding components. These policies are not changed when you upgrade to Cisco UCS Central release 1.5.

  • If you create your own custom host firmware package policy with excluded components, including the local disk component that is excluded by default, you cannot include that host firmware package policy in a service profile associated with a server running a Cisco UCS Manager version prior to 2.2.7. If you do, you will see the following error during service profile association:

    ucs domain does not have the matching server capabilities for this service-profile

If you have issues with your custom host firmware package policies that include excluded components, you can either remove all excluded components in the host firmware package policy, or upgrade your version of Cisco UCS Manager to release 2.2.7 or above.
