Replacement of I/O Cards
Chapter 4 211
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 by using Serviceguard Manager or 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 by using Serviceguard Manager or
the cmrunnode command.
