Shutting Down a Clustered Configuration (BUI)
Use this procedure to shut down a clustered configuration.
-
From one of the peer controllers, go to Configuration > Cluster.
-
Determine the state of both controllers.
In the following figure, the active controller is
controller-a, and the standby controller is
controller-b.
Use the following table to determine the state of each controller.
|
|
|
Active
|
Active
|
Both controllers are running in a normal clustered
condition.
|
Active (takeover completed)
|
Ready (waiting for failback)
|
controller-a owns all of the resources
and is the active controller.
controller-b, is in standby mode and
has no resources. To limit the number of times a pool is
moved, shut down the standby controller first.
|
Active (takeover completed)
|
Rejoining cluster ...
|
controller-b is rebooting and
controller-a has all
resources.
|
Active (takeover completed)
|
Unknown (disconnected or restarting)
|
controller-b is powered off or
rebooting, all of its cluster interconnect links are down,
or clustering has not yet been configured.

-
Log in to the BUI of Controller B and click the power icon
on the left side under the masthead.
Note -
To limit the number of times a pool is moved, shut down the standby
controller first.
-
From the BUI of Controller A, go to Configuration > Cluster to confirm that
Controller B is powered off, with the cluster state: Unknown (disconnected or
restarting).
-
From the BUI of Controller A, click the power icon
on the left side under the masthead.
- (Optional)
To confirm that both controllers are powered off, log into the Oracle ILOM and
enter :
->show /SYS power_state
