How Do I Move HA groups to a new cluster?
Hi - I have an existing cluster on hardware that is being decommissioned. We've built a new cluster independent of the old one (unique cluster number, main.cf, heartbeat network, fencing luns, etc) and zoned the disks to both clusters.
I'd like to know if there is an easy way to move the groups from the old to the new cluster without installing anything new like Global Cluster.
I'm concerned that manually adding the service groups will leave lots of room for error. Can I dump the config in a way that can then be fed to ha commands on the new cluster? Might something like that work in this case with a little tweaking of the output file?
I'd also be okay with a simple cut and paste from the main.cf if it's really that simple. I'd like to know if I could simply change node names or are there more changes required.
- solaris 10 all around
- vcs ha cfs clusters running software version 5.1mp3
- 3 nodes in each cluster
- only filesystems and underlying disk groups are moving, no ip's or other resources
Thanks in advance for any help. I need to pull this off on Saturday and figured I'd ask for any help I can get. I'm also asking support via a case we have open just in case. I'll report my results in the end.
