This procedure adds a node to a disk device group using the scsetup(1M) utility.
The prerequisites to add a node to a VxVM disk device group are:
Superuser privilege on a node in the cluster
The name of the VxVM device group to which the node will be added
The name or node ID of the nodes to add
Become superuser on any node of the cluster.
At the prompt, type the scsetup command.
To work with VxVM disk device groups, type 4 (Device groups and volumes).
The Device Groups Menu is displayed.
To add a node to a VxVM disk device group, type 4 (Add a node to a VxVM device group).
Follow the instructions and enter the device group and node names.
Verify that the node has been added.
Look for the device group information for the new disk displayed by the following command.
# scconf -p
The following example shows the scconf command generated by scsetup when it adds a node (phys-schost-3) to a VxVM disk device group (dg1), and the verification step.
# scsetup scconf a D type=vxvm,name=dg1,nodelist=phys-schost-3 # scconf -p Device group name: dg1 Device group type: VXVM Device group failback enabled: yes Device group node list: phys-schost-1, phys-schost-3
