In the example below, the state of controller B is AKCS_OWNER, with a description of "Active
(takeover completed)."
controller-b:> configuration cluster show
state = AKCS_OWNER
description = Active (takeover completed)
...
peer_state = AKCS_STRIPPED
peer_description = Ready (waiting for failback)
8.
Enter configuration cluster failback, and then enter y to change the cluster to an
Active/Active configuration.
This is not necessary if you want an Active/Passive configuration.
Note -
controller-b:> configuration cluster failback
Continuing will immediately fail back the resources assigned to the cluster
peer. This may result in clients experiencing a slight delay in service.
