Open VMS cluster issue

[Hakan Zanderau ( Anders]

The "Cluster Shutdown" option is a cool cat.

I have never used it working as sysman, but when I teach The OpenVMS Cluster course I show how it works.......suddenly the whole classroom silences.

Back to Nirukshithas problem.

As Robert said.."Check the parameters", just be be sure everything is correctly set.

$ MCR SYSMAN
$ SET ENV/CLU
$ PARAMETER SHOW VOTES
$ PARAMETERS SHOW EXPECTED_VOTES
$ PARAMETERS SHOW DISK_QUORUM

It should read "Votes = 1"
"Expected_votes = 3"
"Disk_Quorum = "diskname""

The CLUSTER SHUTDOWN is ONLY used when shuting down all members. It will only affect the node execting shutdown. It will not leave the cluster until ALL members have reached the same level, wich can be thought of as "hanging".

In a two-node cluster ( with quorumdisk ) you don't have to use REMOVE NODE either.
Quorum will be 2 anyway.

However if you want to shutdown both node at the same time, use SYSMAN...

$ MCR SYSMAN
$ SET ENV/CLU
$ SHUTDOWN /CLUSTER

This will shutdown all nodes in the cluster.

A minor correction to Hakan's post...

To shutdown the entire cluster use:

$ MCR SYSMAN
SET ENVIR/CLUSTER
SHUTDOWN NODE /CLUSTER

Hi Dave

The Problem is other node doesn't come to certain point. It remains without shutting down.I think shutdown doesn't sense to other node.

You have 2 nodes, 1 shelf containing the quorum disk. The question is: how is this shelf connected to the cluster? What are your settings of VOTES and EXPECTED_VOTES for each node and the quorum disk?

Just an idea.
In case the shelf is connected to one system, and shutting down that one, will cause the other node to hang because quorum is lost once the quorum watcher is down.

Nirukshitha,

you do issue the @SYS$SYSTEM:SHUTDOWN ... CLUSTER shutdown on both nodes, do you ?

What happens, if you shut down the 'other' node first ? There could be a problem in SYSHUTDWN.COM preventing/hanging the shutdown of the other node.

What are the last messages shown on the console of BOTH systems ?

Volker.
