Use this procedure to remove a cluster node from the list of potential primaries of a Solstice DiskSuite/Solaris Volume Manager disk device group. Repeat the metaset command for each disk device group from which you want to remove the node.
Verify that the node is still a member of the disk device group and that the disk device group is a Solstice DiskSuite/Solaris Volume Manager disk device group.
Device group type SDS/SVM indicates a Solstice DiskSuite/Solaris Volume Manager disk device group.
phys-schost-1% scconf -pv | grep '(global-galileo)' (global-galileo) Device group type: SDS/SVM (global-galileo) Device group failback enabled: no (global-galileo) Device group node list: phys-schost-1, phys-schost-2 (global-galileo) Diskset name: global-galileo phys-schost-1% |
Determine which node is the current primary for the device group.
# scstat -D |
Become superuser on the node that currently owns the disk device group that you want to modify.
Delete the node's hostname from the disk device group.
# metaset -s setname -d -h nodelist |
Specifies the disk device group name.
Deletes from the disk device group the nodes identified with -h.
Removes the node from the list of nodes that can master the disk device group.
The update can take several minutes to complete.
If the command fails, add the -f (Force) option to the command.
# metaset -s setname -d -f -h nodelist |
Repeat Step 4 for each disk device group from which the node is being removed as a potential primary.
Verify that the node has been removed from the disk device group.
The disk device group name matches the disk set name that is specified with metaset.
phys-schost-1% scconf -pv | grep devicegroup Device group node list: phys-schost-1, phys-schost-2 |
The following example shows the removal of the host name phys-schost-2 from a disk device group configuration. This example eliminates phys-schost-2 as a potential primary for the designated disk device group. Verify removal of the node by running the scstat -D command. Check that the removed node is no longer displayed in the screen text.
