Cisco UCS Domains and Cisco UCS Central
Cisco UCS Central provides centralized management capabilities to multiple Cisco UCS domains across one or more data centers. Cisco UCS Central works with Cisco UCS Manager to provide a scalable management solution for a growing Cisco UCS environment.
Cisco UCS Central does not reduce or change any local management capabilities of Cisco UCS Manager, such as its API. This allows you to continue using Cisco UCS Manager the same way you did before Cisco UCS Central. This also allows all existing third party integrations to continue to operate without change.
Registering Cisco UCS Domains
You can use a Fully Qualified Domain Name (FQDN) or IP address to register Cisco UCS domains in Cisco UCS Central.
To manage Cisco UCS Manager through Cisco UCS Central, you must register the Cisco UCS domains in Cisco UCS Central. You can register a Cisco UCS domain as a part of a domain group or as an ungrouped domain. When you have a domain group, all registered domains in the domain group can share common policies and other configurations.
Note |
During the initial registration process with Cisco UCS Central, all of the active Cisco UCS Manager GUI sessions are terminated. |
Before registering a domain in 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. You cannot use the same hostname for both Cisco UCS Central and Cisco UCS Manager. For standalone mode, use individual VM IP address.
-
Obtain the shared secret that you configured when you deployed Cisco UCS Central.
Note |
|
Warning |
You must upgrade to Cisco UCS Manager Release 2.1(2) or greater before registering with Cisco UCS Central. If you try to register earlier versions of Cisco UCS Manager, the registration will fail. |
Registering a Cisco UCS Domain with the CLI
You can register a Cisco UCS Manager domain to any Cisco UCS Central system. However you can only register the Cisco UCS Manager domain to one Cisco UCS Central system at a time.
Procedure
Command or Action | Purpose | |||
---|---|---|---|---|
Step 1 |
UCSC# connect resource-mgr |
Enters resource manager mode. |
||
Step 2 |
UCSC(resource-mgr) # scope system |
Enters into the system. |
||
Step 3 |
UCSC(resource-mgr) /system # create policy-control-ep UCSM domain IP address admin |
|
||
Step 4 |
UCSC(resource-mgr) /system # Domain Admin Password: password |
|
||
Step 5 |
UCSC(resource-mgr) /system/policy-control-ep # set srcaddrfmt ipv4 { hostname | ipv4 | ipv6 } |
Sets the address format for the domain. |
||
Step 6 |
UCSC(resource-mgr) /system/policy-control-ep # commit-buffer |
Commits the transaction to the system and registers the Cisco UCS Manager domain to Cisco UCS Central. |
||
Step 7 |
UCSC(resource-mgr) /system/policy-control-ep # show detail |
Displays the status of the Cisco UCS Manager domain. |
Example
The following example shows how to register a Cisco UCS Manager domain with Cisco UCS Central:
UCSC# connect resource-mgr
UCSC(resource-mgr)# scope system
UCSC(resource-mgr) /system # create policy-control-ep 10.193.01.01 admin
UCSC(resource-mgr) /system # Domain Admin Password:
UCSC(resource-mgr) /system/policy-control-ep* #
UCSC(resource-mgr) /system/policy-control-ep # set srcaddrfmt ipv4
UCSC(resource-mgr) /system/policy-control-ep # commit-buffer
UCSC(resource-mgr) /system/policy-control-ep # show detail
hostname or ip address: 10.193.190.130
Registration Status: Registered
Cleanup Mode: Localize Global

Unregistering a Cisco UCS Domain with the CLI
Caution |
If you want to unregister any registered Cisco UCS domain in a production system, contact Cisco Technical Support. |
When you unregister a 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 polices still remain local.
Procedure
Command or Action | Purpose | |
---|---|---|
Step 1 |
UCSC# connect resource-mgr |
Enters resource manager mode. |
Step 2 |

Enters into the system. |
Step 3 |
UCSC(resource-mgr) /system # scope policy-control-ep UCSM domain IP address |
Creates a policy control for the UCSM domain. |
Step 4 |
UCSC(resource-mgr) /system/policy-control-ep # set actionevent unregister |
Prepares to unregister the domain. |
Step 5 |
UCSC(resource-mgr) /system/policy-control-ep # commit-buffer |
Commits the transaction to the system and unregisters the Cisco UCS Manager domain from Cisco UCS Central. |
