Cluster Lock disks

Ian Killer_1 — Thu, 25 Jul 2002 15:14:03 GMT

Hi I restored two nodes of a cluster recently. Using tape created by make_tape_recovery. This is a 10.20 cluster. It appears that the recovery didn't write the cluster lock, but the cluster is up and running. SO I'm getting the "cluster lock is missing" message in syslog. I don't have vgcfgbackup files. Does anyone know how to manipulate the bad block relocation table bit that holds the lock?

Halt the cluster, activate the clusterlock vg, re-apply the cluster with the cmapplyconf command, or contact your local HP RC and request the cminitlock unsupported utility

Well,

Try this.

Halt the cluster.

De-activate cluster VG

vgchange -a n

Then re-activate then

vgchange -c n

followed by
Cmcheckconf and then cmapplyconf.

Hi,

Maybe you could try stopping the cluster and then de-activating the shared volumegroup by vgchange -a n (probably not necessary). Disable its cluster awareness with vgchange -c n and then re-enable it again, so it writes the bit again.
vgchange -c y
This should work , I think.

halt the cluster then start again. that's all

in case required do cmhaltcl

vgchange -a n your_vg
vgchange -c n your_vg
vgchange -c y your_vg
start cluster

Good luck!
