OS Upgrade from 11.23 to 11.31 with MC Service Guard Cluster

Hi Experts..

 

I had done the OS Upgrade from 11.23 to 11.31 on Standalone Server..

 

Now the next phase of upgradation of OS with cluster.

 

We are using MC Service Guard Cluster, Please share any suggestion while upgrading the OS from 11.23 to 11.31 with MC Service Guard Cluster.

Re: OS Upgrade from 11.23 to 11.31 with MC Service Guard Cluster

There is much guidance about upgrades in the User Guide for Serviceguard - 'Managing Serviceguard'.  Look at the version of Serviceguard you are using located here:

 

www.hp.com/go/hpux-serviceguard-docs -> HP Serviceguard -> User Guide (http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c03252991/c03252991.pdf)

 

For example, HP Managing Serviceguard A.11.20 - (March 2012) has Appendix D Software Upgrades.  You can update the OS Fusion version (using update-ux) and optionally also update the Serviceguard version at the same time. You can do this with Serviceguard Rolling Upgrade (keep the cluster running and update each Serviceguard node at a time); Or you can do an offline upgrade which means shutdown the cluster, upgrade the nodes (OS fusion and/or Serviceguard), then bring the cluster back up again.

 

In either case, Dynamic Root Disk Utilities are recommended because they allow you to do the upgrade on a cloned boot (inactive) disk.  Overall, this can make the upgrade go quicker, and also give you a safe path back to the original starting point, if something doesn't work as expected.

 

[Please note that now we write: "Serviceguard", rather than "Service Guard", or "ServiceGuard"]

If you are not sure about the MC Service guard upgradation then i would suggest that divide the activity in 2 phase, dont do it parelle. First upgrade the OS with the same MC Serviceguard version and later upgrade MC Serviceguard.
