We follow Jim’s suggestion and keep our kernel patch level the same in our clusters.  The only time they are different is in between the secondary node being patched and the primary being patched, usually 2-3 weeks.  However, we do have a sandbox setup which runs one node running Solaris 10 and the other node running Solaris 8, no issues with that setup, works fine but we wouldn’t do that in a production environment due to best practices.

VCS supports any release and patch level that the version of VCS supports within a single cluster.

So you do not need identical patch levels, or even same OS release.

best practice would be to keep same, but we can easily support multiple versions during upgrades.

Subject: [Veritas-ha] HA nodes Patch levels

Hello colleagues,

We have two nodes for HA cluster installation. They has identical OS version (Solaris 5.9), but different kernel patch level 118558-30 vs. 118558-25.

Is it admissible configuration of cluster or even patch level must be identical?

 

Thanks, Sergey
