Failure of One Server and One Multihost Disk Expansion Unit

If power is lost to one of the Sun Cluster nodes and one multihost disk expansion unit, a secondary node immediately initiates a takeover.

After the power is restored, you must reboot the node, rejoin the node to the configuration by using the scadmin startnode command, and then begin monitoring activity. If manual switchover is configured, use the haswitch(1M) command to manually return ownership of the diskset to the node that had lost power. Refer to "Switching Over Logical Hosts", for more information.

After the diskset ownership has been returned to the default master, any multihost disks that reported errors must be returned to service. Use the instructions provided in the chapters on your disk expansion unit to return the multihost disks to service.

The node might reboot before the multihost disk expansion unit. Therefore, the associated disks will not be accessible. Reboot the node after the multihost disk expansion unit comes up.
