Disabling Automatic Switchover

In clusters providing HA data services, automatic switchover can be set up for the situation where a node fails, the logical hosts it mastered are switched over to another node, and later the failed node returns to the cluster. Logical hosts will automatically be remastered by their default master, unless you configure them to remain mastered by the host to which they were switched.

If you do not want a logical host to be automatically switched back to its original master, use the -m option of the scconf(1M) command. Refer to the scconf(1M) man page for details.

To disable automatic switchover for a logical host, you need only run the scconf(1M) command on a single node that is an active member of the cluster.

# scconf clustername -L logicalhost -n node1,node2 -g dg1 -i qe0,qe0,logaddr1 -m
