Use this procedure to remove a cluster node from the list of potential primaries of a Solaris Volume Manager device group. Repeat the metaset command for each device group from which you want to remove the node.
Caution - Do not run metaset —s setname —f -t on a cluster node that is booted outside the cluster if other nodes are active cluster members and at least one of them owns the disk set.
The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.
This procedure provides the long forms of the Oracle Solaris Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical.
Device group type SDS/SVM indicates a Solaris Volume Manager device group.
phys-schost-1% cldevicegroup show devicegroup
# cldevicegroup status devicegroup
# metaset -s setname -d -h nodelist
Specifies the device group name.
Deletes from the device group the nodes identified with -h.
Specifies the node name of the node or nodes that will be removed.
If the command fails, add the –f (force) option to the command.
# metaset -s setname -d -f -h nodelist
The device group name matches the disk set name that is specified with metaset.
phys-schost-1% cldevicegroup list -v devicegroup
The following example shows the removal of the hostname phys-schost-2 from a device group configuration. This example eliminates phys-schost-2 as a potential primary for the designated device group. Verify removal of the node by running the cldevicegroup show command. Check that the removed node is no longer displayed in the screen text.
