Discovering OpenVMS Clusters

[James Yocum]

When doing an Advanced Find, I cannot discover any OpenVMS clusters. I have discovered the three nodes without a problem. How do I discover the cluster? Could there be a problem with the OpenVMS agents?

I'm not too sure what is happening with the VMS Agents, I just checked the other day and there doesn't seem to have been any developments for ages.

I've not really looked at our slowly shrinking VMS cluster since moving to HPSIM. But, it has not been recognised automatically as it was in CIM 7.

The agents I have date from March 2004. I've not really looked at any docs for OpenVMS and HPSIM. I might have a play if I get time.

What version of OpenVMS and agents?

I had a similar problem even after following the install steps.

In order for the cluster to be discovered, the WBEM$CLUSTER_NODE logical needs to be defined as the name of the cluster. The instructions tell you to edit the WBEM$LOGICALS.COM file to accomplish this task and the WBEM$LOGICALS.COM file is called during the agent startup. The problem was the timing of when the WBEM$LOGICALS.COM file was being executed.

After some work by HP support it was determined that the delivered WBEM$STARTUP.COM was calling this procedure after it had already started the agents that use it. After moving the call to this procedure to sooner in the startup procedure, my HPSIM was able to discover the cluster.

I had the problem with OpenVMS 7.3-1 and agent V3.0-36.

Terry, your suggestion did the trick! Thanks for your help.

The suggestion from Terry Bjerken worked. The global cluster logical was initialized and the OpenVMS agents restarted.
