clustername

Hello to all,

is there a way to change the clustername?

Regards, Alfons

With my crystal ball, I'm seeing that you are talking about Serviceguard yes?

The answer is yes, there is a way, but why do you want to do this?

The cluster name is directly associated with the unique cluster ID loaded into the VGDA (LVM structure) on each of the disks used by the packages in the cluster.  If the cluster name is changed, the cluster ID must be removed and replaced with the new ID associated with the new cluster name for all the volume groups in the cluster.

Which basically means saving the package and cluster configs to text files using cmgetconf, stopping the cluster using cmhaltcl, deleting the existing cluster config using cmdeleteconf, changing the cluster name in the cluster config text file, re-applying the cluster and package configs using cmapplyconf, and then restarting the cluster using cmruncl

Lots of work, for what is usually a cosmetic change - the only time you should really consider doing this is if you have a duplicate cluster name in the same subnet, or using the same quorum server.

Hello Duncan,

I think You don't need a crystall ball for that. It is the serviceguard section off the forum;)

If it would be easy,  I would think about changing the name.

Thanks for the answer.

D'oh! I still can't get used to these new forums! I miss ITRC!

No problem Duncan.

You are not the only one that misses ITRC......

Thanks, Uday.

I will try to find some offline time to change it.
