Serviceguard Extension for RAC Version A.11.19 Release Notes (May 2010)

In addition, all the limitations for non-rolling upgrades listed in Appendix A of Using Serviceguard
Extension for RAC also apply to non-rolling upgrades using DRD. You should also read the section
on “Non-Rolling Software Upgrades” in that Appendix before you proceed.
Steps for a Non-Rolling Upgrade Using DRD
Use the following steps for a non-rolling software upgrade using DRD:
1. Create a clone root disk for each node.
2. Upgrade each clone disk to the new HP-UX release (if necessary), including Serviceguard (using
drd runcmd update-ux), or upgrade Serviceguard alone (using drd runcmd swinstall).
3. Upgrade each clone disk to the new release of SGeRAC.
4. Halt Oracle (RAC, Clusterware) on all nodes in the cluster.
5. Halt all nodes in the cluster:
cmhaltcl -f
6. Reboot the nodes from their updated clone root disks.
7. Restart the cluster:
cmruncl
8. If necessary, upgrade all the nodes in the cluster to the new Oracle (RAC, Clusterware) release.
9. Restart Oracle (RAC, Clusterware) on all nodes in the cluster and configure the
Serviceguard/SGeRAC packages and Oracle as needed.
10. Verify that the cluster is healthy, the packages can run, and applications are functioning properly.
If the cluster is not healthy or the packages and applications are not functioning properly, and you
cannot fix the problems, you can revert to the original (pre-upgrade) cluster by halting the cluster
(cmhaltcl), rebooting each node from its original (pre-upgrade) root disk, and restarting the cluster
(cmruncl).
CAUTION:
You must reboot all the nodes from their original disks before restarting the cluster. Do not try to restart
the cluster with some nodes booted from the upgraded disks and some booted from the pre-upgrade
disks.
Removing SGeRAC
To remove your software, run the SD-UX swremove command.
NOTE:
If you are removing SGeRAC and wish to continue using the cluster as an Serviceguard cluster. The
steps are slightly different. See section “Removing Serviceguard Extension for RAC Without Removing
Serviceguard” on page 20.
Use the following steps to remove the software from each node:
