Could I change FIRST_CLUSTER_LOCK_PV?

[Carme Torca]

Hi,
I have this error in the syslog

Oct 20 10:37:52 hp9ges02 cmcld: WARNING: Cluster lock disk /dev/dsk/c4t1d0 has failed: I/O error
Oct 20 10:37:52 hp9ges02 cmcld: Until it is fixed, a single failure could
Oct 20 10:37:52 hp9ges02 cmcld: cause all nodes in the cluster to crash

This disk is the FIRST_CLUSTER_LOCK_PV, and now I haven't got this disk.... Could I change to another disk?, what I have to do?

Thanks!!
Carmen.

Here is a cookbook:

How to initialize the cluster lock disk(s) using cmapplyconf:
â ¢ Halt the entire cluster.
# cmhaltcl -f
â ¢ Perform the following command from all nodes in the cluster to remove the cluster
flag from cluster lock VG(s).
# vgchange -c n /dev/vgxxx
â ¢ Activate cluster lock VG(s) on one node only:
# vgchange -a y /dev/vgxxx
â ¢ Perform cmapplyconf on the node where you activated the cluster lock VG(s). The
cluster flag is added back to the VG automatically.
# cmapplyconf -C ........
â ¢ Perform vgcfgbackup to backup the cluster lock information:
# vgcfgbackup /dev/vgxxx
â ¢ Deactivate cluster lock VG(s):
# vgchange -a n /dev/vgxxx
â ¢ Run vgcfgbackup on all other cluster nodes also:
# vgchange -a r vgxxx
# vgcfgbackup vgxxx
# vgchange -a n vgxxx
â ¢ Restart the cluster:
# c

First check if the disk is OK?
(pvdisplay, diskinfo, vgdisplay)

Also use cminitlock command to check if there is anything wrong with the disk. If bad replace it with new one.
(run cminit in preview mode)

Use cminitlock to check it.
