Use this procedure to remove a cluster node from the list of potential primaries of a VERITAS Volume Manager (VxVM) disk device group (disk group).
Verify that the node is still a member of the group and that the group is an VxVM device group.
Device group type VxVM indicates a VxVM disk device group.
phys-schost-1% scconf -pv | grep '(global-galileo)' (global-galileo) Device group type: VxVM (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% |
Become superuser on a current cluster member node.
Execute the scsetup(1M) command.
# scsetup |
The Main Menu is displayed.
To reconfigure a disk device group, type 4 (Device groups and volumes).
To remove the node from the VxVM disk device group, type 5 (Remove a node from a VxVM device group).
Follow the prompts to remove the cluster node from the disk device group. You will be asked for information about the following:
VxVM device group
Node name
Verify that the node has been removed from the VxVM disk device group(s).
# scconf -p | grep Device |
This example shows removal of the node named phys-schost-1 from the dg1 VxVM disk device group.
[Determine the VxVM disk device group for the node:] # scconf -p | grep Device Device group name: dg1 Device group type: VxVM Device group failback enabled: no Device group node list: phys-schost-1, phys-schost-2 Device group diskset name: dg1 [Become superuser and execute the scsetup utility:] # scsetup Select Device groups and volumes>Remove a node from a VxVM device group. Answer the questions when prompted. You will need the following information. You Will Need: Example: VxVM device group name dg1 node names phys-schost-1 [Verify that the scconf command executed properly:] scconf -r -D name=dg1,nodelist=phys-schost-1 Command completed successfully. Quit the scsetupDevice Groups Menu and Main Menu. [Verify that the node was removed:] # scconf -p | grep Device Device group name: dg1 Device group type: VxVM Device group failback enabled: no Device group node list: phys-schost-2 Device group diskset name: dg1 |
