4.2.3 How to Halt a Sun Cluster Node

Shut down any Sun Cluster node by using the halt(1M) command or the uadmin(1M) command.

If the membership monitor is running when a node is shut down, the node will most likely take a "Failfast timeout" and display the following message:

panic[cpu9]/thread=0x50f939e0: Failfast timeout - unit 

You can avoid this by stopping the membership monitor before shutting down the node. Refer to the procedure, "4.2.2 How to Stop Sun Cluster on All Nodes", for additional information.
