error regarding cluster lock disk

sbb — Sun, 15 Jun 2008 08:42:24 GMT

Jun 14 00:23:23 KBXSBUP cmcld: WARNING: Cluster lock on disk /dev/dsk/c5t0d0 is missing!
Jun 14 00:23:23 KBXSBUP cmcld: Until it is fixed, a single failure could Jun 14 00:23:23 KBXSBUP cmcld: cause all nodes in the cluster to crash

The above error I am getting after replacement of mirror disk which is in cluster.
cluster log vg is VG02 and cluster log disk is c5t0d0. I replaced the disk c5t0d0.

Hi

could you submit following outputs

vgdisplay -v vg02
pvdisplay /dev/dsk/c5t0d0

Best Regards

Hi

Most probably your ioscan output is good about c5t0d0 and you are saying these errors came after replacement of disk

Did you check frdump with cmfmtfr

/usr/contrib/bin/cmfmtfr frdump.cmcld.8

Best Regards

Hi,

if you can take the cluster down, try rebuilding the cluster binary with cmcheckconf and cmapplyconf.

Kenan.

Hi sbb:

I'm in agreement with Keenan. Cluster lock disks have no concept of mirroring. And only one is needed during cluster formation and not two. You can't mirror the cluster lock disk.

From what you've described you've performed a vgcfgrestore, but this restore is probably before the cmquerycl, cmapplyconf, etc. So this restore doesn't know that its a cluster lock disk. It has no cluster ID.

Another cmapplyconf must be performed with the cluster halted to reestablish
the disk listed in the cluster ASCII file as the clusterlock disk.
