Re: cluster lock failure
yes you are right. This is a storage LUN.
I am not able to see this PV/LUN on other side. but this PV is persent in the .asci file of cluster on affected node.
But on other node the entry of this PV is not available in .ascii file.
this error comming since last 2 months but nobody noticed this.

SolutionMay be that the LUN c16t0d1 has been removed from the cluster. You can re-configure the lock disk using the below steps.
- identify alternate LUN which is accessible to both the nodes
- Update the cluster ASCII file with the corresponding device files on each of these nodes as well as lock VG to point alternate LUN and VG
- Take down the cluster
- Apply the new configuration using cmapplyconf.
This would make the identified LUN as the cluster lock disk and then you should not be seeing those errors in the syslog.

Re: cluster lock failure
I had a word with storage team and got to know that they made some changes on storage.
Now I'll take the downtime from customer and correct the cluster's .ascii file.
Thanks to all for valuable time
