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 Cisco UCS Central to manage a Cisco UCS domain, you need to register that domain. When you register, you must choose which types of policies and other configurations will be managed by Cisco UCS Central and Cisco UCS Manager. Cisco UCS Central can manage the same types of policies and configurations for all registered Cisco UCS domains. You can also choose to have different settings for each registered Cisco UCS domain.
Perform the following before registering a Cisco UCS domain with Cisco UCS Central:
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 was configured when Cisco UCS Central was deployed.
