WebManager and the failover group successfully stops
• The cluster is stopped by the clpcl command or WebManager and the failover group
successfully stops
• The server fails and there is no failover group to perform failover from the failing server
to another server
(including when the failover group is not activated in the failing server)
� Forced stop is performed when the server is failing and there is a failover group to perform
failover from the failing server to another server
