Troubleshooting Your Cluster
Replacement of I/O Cards
Chapter 8330
Replacement of I/O Cards
After an I/O card failure, you can replace the card using the following
steps. It is not necessary to bring the cluster down to do this if you are
using SCSI inline terminators or Y cables at each node.
1. Halt the node. In Serviceguard Manager, select the node; from the
Actions menu, choose Administering Serviceguard -> Halt node. Or,
from the Serviceguard command line, use the cmhaltnode command.
Packages should fail over normally to other nodes.
2. Remove the I/O cable from the card. With SCSI inline terminators,
this can be done without affecting the disks or other nodes on the
bus.
3. Using SAM, select the option to do an on-line replacement of an I/O
card.
4. Remove the defective I/O card.
5. Install the new card. The new card must be exactly the same card
type, and it must be installed in the same slot as the card you
removed.
6. In SAM, select the option to attach the new I/O card.
7. Add the node back into the cluster. In Serviceguard Manager, select
the node; from the Actions menu, choose Administering Serviceguard
-> Move node. Or, from the Serviceguard command line, issue the
cmrunnode command.
