Hi Eric,
That's funny, I've been told by Veritas Support that Veritas does not
support nodes in the same Cluster running at different Solaris patch
levels, no less different versions of Solaris.

Re: [Veritas-ha] best way for
patching of cluster servers

Hi Upen,
My guess is you spoke with Sun sales when you asked this question. Try
rephrasing your question to your Sun contact. Ask him/her if they will
support a collection of systems running Solaris 9 running at different
patch levels, without regard to them being clustered. That you’re running
VCS on these systems isn’t Sun’s support problem, it’s ours, and we
unequivocally support mixing not only different patch levels but different
Solaris versions in the same cluster. We do this so you can leverage the
cluster as an operational support tool to enable rolling upgrades of the OS
with a minimum of application down time.
The response you got sounds like it came from someone interested in selling
Sun Cluster. Just because THEY won’t support different patch levels and
Solaris versions in the same cluster doesn’t mean WE won’t. :-)
Cheers!
Eric

Thanks Eric
One question,
Does Veritas/symantec provide support for Patching Sun servers involved in
Veritas -ha cluster. I contacted Sun for support (we have valid gold
contract) but they still refused to support as machines are part of veritas
cluster.
I am not having Veritas contract number but I know that our contract was
renewed and I have valid contract. Is there anyway I can find out from
symantec/veritas what is my contract number if I am able to give them
necessary information-machine serial and company info. I don't know
whosoever renewed contract at work place does not seem to be of much help
in term of contract number information ...
I am not able to see the site properly on my linux machine and may be I am
not looking at proper place..if anyone can give me some contact of
veritas/symantec where I can find this information about my contract
details and support for patching sun after this..
Thanks

The typical approach to applying OS patches in a clustered environment is
to patch an idle server, let it reboot and rejoin the cluster, and make
sure it's running OK. If it is, use the cluster software to switch
application(s) from an active server to the one you just patched, and if
the app comes up successfully there, apply the patch to the server that's
now idle. Keep doing this until all nodes in the cluster have been
patched.

Hi
when it is patching of Sun stand alone servers I can patch them and I know
after reboot everything will be fine.
I wanted to how to patch Veritas-ha clustered Sun OS 5.9 Machines. Right
now the cluster service and application services are running on Server 2. I
am not sure after patching if something messes the cluster or applications
running. Please let me know best practices to update patches on Cluster
servers so that machines will have least down time. We are running
Veritas-ha with blackboard application services which includes apache +
oracle applications too.
Please let me know if any more details are required to help..
Thanks in advance
