This topic describes how to change which server in the SAN File System cluster serves as the master.
You must have Operator or Administrator privileges to perform this task.
This task can be performed only at the administrative command-line interface. You may need to convert a subordinate server to the master server in the event of an irrecoverable loss of the original cluster master server. Such a loss might be due to hardware failures, software failures, or partitioned networks.
After issuing the setmaster command, you must manually edit the tank.properties file on the subordinate server that will become the master and set the IsMaster property to true.
