Replacing SBus Cards

Replacement of SBus cards in Sun Cluster nodes can be done by switching over the data services to the node that is functioning and performing the hardware procedure to replace the board. The logical hosts can be switched back to the default masters following the procedure.

How to Replace SBus Cards

1. Switch ownership of the logical hosts from the Sun Cluster node that needs an SBus card replaced.

   For instance, if the board is being replaced on the physical host phys-hahost2, enter the following:

   phys-hahost1# haswitch phys-hahost1 hahost1 hahost2

2. Stop Sun Cluster on the affected node.

   Run the scadmin(1M) command with the stopnode option on the host that has the failed SBus card

   phys-hahost2# scadmin stopnode

   .

3. Halt and power off the affected node.

4. Perform the hardware replacement procedure.

   Refer to the instructions in the appropriate hardware service manual to replace the SBus card.

5. Power on the node and start the cluster software on the node.

   # scadmin startnode

   The node automatically will rejoin the Sun Cluster configuration.

6. Switch the logical hosts back to the default masters, if necessary.

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