3.3.13 How to Add a Node to a Disk Device Group (VERITAS Volume Manager)

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

1. Become superuser on a node of the cluster.

2. Enter the scsetup(1M) utility

   The Main Menu appears.

   # scsetup

3. To work with VxVM disk device groups, enter 3 (Device groups and volumes).

   The Device Groups Menu appears.

4. To add a node to a VxVM disk device group, enter 4 (Add a node to a VxVM device group).

   Follow the instructions and enter the device group and node names.

5. Verify that the node has been added.

   Look for the device group information for the new disk displayed by the following command.

   # scconf -p

3.3.13.1 Example--Adding a Node to a VERITAS Volume Manager Disk Device Group

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.

# scconf -a -D type=vxvm,name=dg1,nodelist=phys-schost-3
# scconf -p 
...
Device group name:                              dg1
   Device type:                                 VXVM
   Failback enabled:                            yes
   Node preference list:                        phys-schost-1, phys-schost-3
