Installing patches in a 2 node Service Guard cluster

[EJ Stremler]

I ran the analysis for the June 2005 patch bundles for HPUX 11.11. These systems that I would like to patch are in a 2 node Service Guard cluster. The analysis gives one Error:
------------------------------------------
* Reading source for file information.
ERROR: Cluster must be halted on current node in order to swinstall ERROR: The "checkinstall" script for "PHSS_29053" failed (exit code "1"). The script location was "/var/tmp/BAAa26323/catalog/PHSS_29053/pfiles/checkinstall".
* This script had errors and the execution of this product cannot proceed until the problem is fixed. Check the above output from the script for further details.
-----------------------------------------
I do have an ample downtime window for these 2 systems in the cluster. So, should I do a cmhaltcl first to take down the cluster, then install the patches. And also make sure /etc/rc.config.d/cmcluster shows AUTOSTART_CMCLD=0 so the cluster does not start up automatically?, because the patch bundle installation will re-boot the system.

You don't need to halt the entire cluster... only the node you are installing it on... unless you plan to patch both nodes simultaneously. See the Special Installation Instructions in the patch text.

BTW, this appears to be an old patch that's been superceded by PHSS_32727. Search patch/firmware database on ITRC for further information.

I do plan to install the patches on these 2 systems simultaneously. These systems are npar'd, HP needs to come in after to do some back plane work, so i have to take the whole complex down anyway. Why they set up a HA cluster on the same piece of hardware? who knows... But i probably will halt the packages first, (cmhaltpkg), then do a cmhaltcl... Sound reasonable? Just wanted to put this out here first to see what other folks say...

[Jeff_Traigle · Accepted solution]

Sounds good. You don't even really need to halt the packages first since cmhaltcl will do that automatically for any packages that are running, but it never hurts to do so.

[Jeff_Traigle]

Assuming you use the -f option on cmhaltcl. Without the -f option, cmhaltcl will fail if there are running packages.
