3.3.15 How to Remove a Node From a Disk Device Group (VERITAS Volume Manager)
Use this procedure to remove a cluster node from an existing cluster disk device group (disk group) running VERITAS Volume Manager (VxVM).
-
Determine the disk device group of which the node to be removed is a member.
# scstat -D
-
Become superuser on a current cluster member node.
-
Execute the scsetup utility.
# 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:
# scconf -p | grep Device
3.3.15.1 Example--Removing a Node From a Disk Device Group (VxVM)
This example shows removal of the node named phys-schost-4 from the dg1 VxVM disk device group.
[Determine the disk device group for the node:] # scstat -D -- Device Group Servers -- Device Group Primary Secondary ------------ ------- --------- Device group servers: dg-schost-1 phys-schost-1 phys-schost-2 [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-4 Command completed successfully. Quit the scsetup Device 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-3 Device group diskset name: dg1 |
