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. Halt the node by using
Serviceguard Manager or the cmhaltnode command. Packages should fail over normally to other
nodes. 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. Using SAM, select the option to do an on-line replacement
of an I/O card. Remove the defective I/O card. 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. In SAM, select the option to attach the new I/O
card. Add the node back into the cluster by using Serviceguard
Manager or the cmrunnode command.
