trucluster patching

[edi_4]

What is the procedure to patch TruCluster 5.1b from patck kit1 to patch kit 5.
Is there any problem to expect?

First, there are two ways to patch TruCluster: rolling and non-rolling. Non rolling is simple to do and is much faster method but needs downtime of entire cluster. I had problems only with rolling upgrade method.
Procedure:
Unpack patch kit somewhere. Go to this directory (for example /usr/patche/patch_kit) and run ./dupatch.
Select option Check and install in multiuser mode. You MUST patch cluster in multiuser mode. Follow the instructions and patch the cluster. That may take a long time.
Backup the cluster before patching.

The downloaded patch file contains a directory that contains all the documentation for patching the system.

I heard that some people had problems installing PK5. You should always run a Patch Preinstallation Check / Patch Baseline Analysis/Adjustment.

edi,

I've only done non-rolling patch uprgades as well. This is how I do it

o Download the patch and unpack it into /var/adm/patch.
# cd /var/adm/patch
# tar -xf

o cd down to the patch_kit sub-directory and run ./dupatch

o Perform baslining (option 5) and review the output. Make any changes that's necessary.

o Perform pre-installation check only (option 1). Verify that no patches will fail.

o Shutdown all services like Oracle databases, etc. To prevent users from logging in touch /etc/nologin (remember to delete this file after you're done)

o Perform patch installation in muli-user mode. At one point all members in the cluster will reboot. Just about every time I've done this, one of our 5 cluster members fails to reboot with some type of panic. I just manually boot that member and everything is fine.

Hope this helps,
Vic

Thank anybody - Does it matter on which cluster member to run ./dupatch?
Thank you!

[Vladimir Fabecic]

I ussualy do it from "leading member", member that created cluster. But just for patching, it is not so important.

[Venkatesh BL]

Any member would do.

[Ivan Ferreira]

You can do it on any member.

I did installation without problems - thank to all.
