   phys-hahost1# scadmin stopnode

2. Add or remove the network adapters.

   Use the procedures described in "6.4 Adding and Removing Network Interfaces".

3. Run the pnmset(1M) command to reconfigure backup groups.

   Use the pnmset(1M) command to reconfigure backup groups as described in Step 4 of the procedure "6.2.1 How to Set Up PNM".

   phys-hahost1# pnmset

4. Restart the Sun Cluster software on the node.

   Restart the node by running the following command from the administrative workstation:

   phys-hahost1# scadmin startnode

5. Repeat Step 1 through Step 4 for each node you want to reconfigure.
