Cluster lock disk

[sosel]

All,

We had to change the cluster lock disk last week and did all cmhaltcl, cmcheckconf, cmapplyconf etc.. etc

But error msg started to pop in the syslog as follows:

"Sep 28 04:39:59 turner cmcld: WARNING: Cluster lock on disk /dev/dsk/c7t5d7 is missin
g!
Sep 28 04:39:59 turner cmcld: Until it is fixed, a single failure could
Sep 28 04:39:59 turner cmcld: cause all nodes in the cluster to crash"

Has any one had the same sort of problem even after the configuration of new cluster lock disk?

Regards
Sosel

Did you remove the cluster lock VG from the cluster before changing the disk using

vgchange -c n and then reactivating it normally .

Also when you did a cmapplyconf was you cluster lock VG active . It has to be activated so that the SG recognises it as cluster lock vg/pv when creating the binary files .

Hi,

We have had the problem before, the cluster lock disk was removed completely from the volume group before removing and once it was added back in the cluster lock info was missing.

We had to halt the cluster & run a cmapplyconf to reapply the binaries, and the problem did go away.

Regards,

Hilary

We followed all the steps except vgchage -c n before cmapplyconf
