Hi All,

When can we see these messages in the syslog.

We have service guard cluster software installed on hpux 11iv3 servers.
We were able to see the below error so many times in our syslog messages

cmdisklockd[4490]: Unable to convert device to I/O tree node: I/O tree node does not exist.

What is the meaning of this error, how to analyse the problem.

Thanks,

Looks like a problem with lock disks.
You might also want to check the cluster log under /etc/cmcluster/packagename/

Run cmviewcl -v to confirm.

If the state is unknown, then run ioscan -fnC disk , and identify the disk in question, and troubleshoot further (check SAN etc.)
You want a CLAIMED for disks you are using.

If you changed the layout of cluster (added new disks or hosts), you will need to run ioscan on all nodes of the cluster.

Hi,

Thanks for your help.
Mistakenly we unassingned the disks, that's why we got those errors.
