Registering Cisco UCS Domains with Cisco UCS Central

Registering Cisco UCS Domains with Cisco UCS Central

This chapter includes the following sections:

Registration of Cisco UCS Domains

You can have Cisco UCS Central manage some or all of the Cisco UCS domains in your data center.

If you want to have Cisco UCS Central manage a Cisco UCS domain, you need to register that domain. When you register, you need to choose which types of policies and other configurations, such as backups and firmware, will be managed by Cisco UCS Central and which by Cisco UCS Manager. You can have Cisco UCS Central manage the same types of policies and configurations for all registered Cisco UCS domains or you can choose to have different settings for each registered Cisco UCS domain.

Before you register a Cisco UCS domain with Cisco UCS Central, do the following:

  • Configure an NTP server and the correct time zone in both Cisco UCS Manager and Cisco UCS Central to ensure that they are in sync. If the time and date in the Cisco UCS domain and Cisco UCS Central are out of sync, the registration might fail.
  • Obtain the hostname or IP address of Cisco UCS Central
  • Obtain the shared secret that you configured when you deployed Cisco UCS Central

Note


You cannot change or swap the IP addresses used by Cisco UCS Manager in a domain that is registered with Cisco UCS Central. If you need to change or swap that IP address, you must first unregister the domain from Cisco UCS Central. You can reregister the Cisco UCS domain after you have changed or swapped the IP address.


Policy Resolution between Cisco UCS Manager and Cisco UCS Central

For each Cisco UCS domain that you register with Cisco UCS Central, you can choose which application will manage certain policies and configuration settings. This policy resolution does not have to be the same for every Cisco UCS domain that you register with the same Cisco UCS Central.

You have the following options for resolving these policies and configuration settings:

  • Local—The policy or configuration is determined and managed by Cisco UCS Manager.
  • Global—The policy or configuration is determined and managed by Cisco UCS Central.

The following table contains a list of the policies and configuration settings that you can choose to have managed by either Cisco UCS Manager or Cisco UCS Central:

Name Description

Infrastructure & Catalog Firmware

Determines whether the Capability Catalog and infrastructure firmware policy are defined locally or come from Cisco UCS Central.

Date & Time

Power Supply Unit

Determines whether power supply units are defined locally or in Cisco UCS Central.

Registering a Cisco UCS Domain with Cisco UCS Central


Note


You cannot change or swap the IP addresses used by Cisco UCS Manager in a domain that is registered with Cisco UCS Central. If you need to change or swap that IP address, you must first unregister the domain from Cisco UCS Central. You can reregister the Cisco UCS domain after you have changed or swapped the IP address.


Before You Begin

Configure an NTP server and the correct time zone in both Cisco UCS Manager and Cisco UCS Central to ensure that they are in sync. If the time and date in the Cisco UCS domain and Cisco UCS Central are out of sync, the registration might fail.

Procedure
     Command or ActionPurpose
    Step 1UCS-A# scope system 

    Enters system mode.

     
    Step 2UCS-A/system # create control-ep policy ucs-central  

    Creates the policy required to register the Cisco UCS Domain with Cisco UCS Central.

    ucs-central can be the hostname or IP address of the virtual machine where Cisco UCS Central is deployed.

    Note   

    If you use a hostname rather than an IPv4 or IPv6 address, you must configure a DNS server. If the Cisco UCS domain is not registered with Cisco UCS Central or DNS management is set to local, configure a DNS server in Cisco UCS Manager. If the Cisco UCS domain is registered with Cisco UCS Central and DNS management is set to global, configure a DNS server in Cisco UCS Central.

     
    Step 3Shared Secret for Registration: shared-secret  

    Enter the shared secret (or password) that was configured when Cisco UCS Central was deployed.

     
    Step 4UCS-A/system/control-ep # commit-buffer 

    Commits the transaction to the system configuration.

     

    The following example registers a Cisco UCS Domain with a Cisco UCS Central system at IP address 209.165.200.233, and commits the transaction:

    UCS-A# scope system
    UCS-A /system # create control-ep policy 209.165.200.233
    Shared Secret for Registration: S3cretW0rd!
    UCS-A /system/control-ep* # commit-buffer
    UCS-A /system/control-ep #
    What to Do Next

    Configure policy resolution between Cisco UCS Manager and Cisco UCS Central.

    Configuring Policy Resolution between Cisco UCS Manager and Cisco UCS Central

    Before You Begin

    You must register the Cisco UCS Domain with Cisco UCS Central before you can configure policy resolution.
