The prerequisites to add a node to a VxVM 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
Start the clsetup utility.
The Main Menu is displayed.
The Device Groups Menu is displayed.
To add a node to a VxVM device group, type the number that corresponds to the option for adding a node to a VxVM device group.
Follow the instructions and type 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.
# cldevicegroup show devicegroup
The following example shows the scconf command generated by clsetup when it adds a node (phys-schost-3 ) to a VxVM device group (dg1 ), and the verification step.
# clsetup cldevicegroup add-node -n phys-schost-3 dg1 # cldevicegroup show dg1 === Device Groups === Device Group Name: dg1 Type: VxVM failback: yes Node List: phys-schost-1, phys-schost-3 preferenced: no numsecondaries: 1 diskgroup names: dg1
