To remove a quorum witness, you must first stop it; see

“Stopping a Quorum Witness” (page 266)

.

Then issue the remove command:

# setrcopytarget witness remove

You can also tunnel the remove command to the other HP 3PAR OS using the –remote option:

# setrcopytarget witness remove –remote

Auto Failover Policies

A volume group must have the auto_failover policy set if it is to be valid for automated and
transparent failover. Issue the following command on each group that is to have auto failover
functionality:

# setrcopygroup pol auto_failover

NOTE:

This command can be issued only on a group that is in the source role. The policy is also

assigned to the target group when issued on the source.

To remove the auto_failover policy from a group, set the group policy to no_auto_failover:

# setrcopygroup pol no_auto_failover

NOTE:

Setting the group policy to no_auto_failover will exclude the group from the auto

failover feature, and it will not fail over in a disaster situation.

To show the quorum status qualifier, issue the showrcopy command with the –qw (quorum witness)
option. The quorum status is shown in the Q-Status-Qual field. For example:

# showrcopy -qw targets
