Hi,
The VCS 5.0 statement below doesn't address the issue of nodes in the same
Cluster running on different patch levels of Solaris.
It also doesn't seem to address whether nodes in a Cluster can run
different Solaris versions (ie. nodeA has Solaris 8 and nodeB has Solaris
9).
Seems to me the intent of the statement is to say that VCS 5.0 Cluster runs
on Solaris 8 or Solaris 9 or Solaris 10. It doesn't seem directed toward
the mixing of different patch levels or versions on nodes within any given
Cluster.
But this would be a good issue to understand much better. We're actually
starting to do Solaris patching on our VCS Clusters much more frequently.
And it might be helpful if we're all working with the same definition of
"supported", which seems to me can have many different meanings.
Does "support" mean that Veritas has tested the combinations and they
worked?
And that if a customer finds a problem due to a certain combination, that
Veritas will provide a bug fix for the problem?
Another is whether we're saying that installing Solaris patches on one
node, then bringing the node into the Cluster, check, and then installing
Solaris patches on the next node is what's ok. Or whether installing on one
node, bringing it into the Cluster, failing Production over to it, ... and
then leaving the one node with Solaris patches and the 2nd node with NO
Solaris patches for a few days, say, before installing patches on the 2nd
node is what we're saying is ok.
I think part of the concern about nodes with differences is in the llt and
gab protocols, which operate at a lower level.
If you can help us all with this, it would be appreciated...

RE: [Veritas-ha] best way for
patching of cluster servers
It's likely that this is a hold over from earlier support statements.
>From the VCS 5.0 Release Notes:
Supported software for VCS cluster nodes
Solaris 8, 9, and 10 (32-bit and 64-bit) SPARC platforms
For each platform, we recommend applying the latest Solaris operating
system patches available from Sun. See the following site:
http://sunsolve.sun.com
But we've supported mixed Solaris versions and patch levels for several
releases of VCS.

We will get that resolved (Eric and I).

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.

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
