Serviceguard error trying to rename a cluster.

[mpua]

Hi,

I created a new ServiceGuard cluster but I forgot to give it a proper name so I decided to change the default name "cluster1). I did the following steps:

1) cmhaltcl
2) cmdeleteconf
3) cmapplyconf -v -k -C /etc/cmcluster/mycluster/cluster.ascii

Im stuck at this since I cant apply the new configuration file with the new name, receiving this error message:

Defaulting MAX_CONFIGURED_PACKAGES to 300.
Checking nodes ... Done
Checking existing configuration ... cmapplyconf : Command can not be executed remotely.
Addition of node sdppapl1 to cluster PRUEBA-NFS is possible only when
command is issued from a node which is already a part of the cluster.
Please login to one of the cluster member nodes of cluster PRUEBA-NFS
and reissue the command.

Any way to fix this?

I tend to build my clusters by simply starting with one node.

It's just a suggestion, but you might try rebuilding your new cluster, with just the one node.
Then once it builds, add the other node.

Just a quick thought,

We don't know if the content of /etc/cmcluster/mycluster/cluster.ascii is valid.

Use cmquerycl -C new.ascii -n -n ...

Include all nodes that will be in the cluster.
This will create a fresh cluster configuration ASCII file. Then modify the cluster name in the file and other parameter values as needed, then use cmapplyconf.

HI

revert to original configuration.

halt the cluster cmhaltcl -f

1) cmdeleteconf -P to remove package conf

2) cmdeletconf -c <> to remove the cluster config

halt the cluster cmhaltcl -f
3) edit the cluster config file for new cluster name

4) cmchekconf and applyconf
5) cmruncl
6) add packahes using cmcheckconf -P <> and cmapplyconf -P <>

regards

Hi!

Problem solved. What happened was that I was trying to rename the cluster with the same name of another cluster in the same subnet so I got that error, simply changed the named to whatever and it worked.

Thanks folks!
