Adding Board-Level Modules

Adding or replacing board-level modules such as SIMMs and CPUs involves both software and hardware procedures.

How to Add Board-Level Modules

1. Stop Sun Cluster on the node that is to receive the board-level module.

   In this example, phys-hahost2 will be the first to receive the board-level module.

   phys-hahost2# scadmin stopnode

2. Halt the node.

   phys-hahost2# halt

3. Power off the node.

4. Install the board-level module using the instructions in the appropriate hardware manual.

5. Power on the node.

6. Perform a reconfiguration reboot.

   ok boot -r

7. Start the cluster software on the node.

   # scadmin startnode

8. Repeat Step 1 through Step 7 on the other Sun Cluster nodes that need a similar hardware upgrade.

9. Switch each logical host back to its default master, if necessary.

   If manual mode is not set, an automatic switchback will occur.
