Removing a CMC

Removing a CMC


Remove a central management console (CMC) if it has failed.



Determine whether the CMC to be removed is active or standby.

  • If the standby CMC has failed, remove it directly.
  • If both the active CMC and the standby CMC have failed, replace them as follows:
    1. Observe the indicators of both CMCs to identify the active and standby CMCs.
    2. Replace the standby CMC.

      After you replace the standby CMC and the health indicator of the standby CMC is steady green, wait for 5 minutes until data is synchronized from the active CMC to the standby one.

    3. On the active CMC, run the smmset [-l smm] -d failover -v 1 command to perform an active/standby failover.
    4. Replace the current standby CMC (original active CMC).

Do not remove two CMCs at the same time.


No data preparation is required for this operation.
