Serviceguard Extension for RAC Version A.11.19 Release Notes, October 2009 (T1907-90051)

8. If necessary, upgrade all the nodes in the cluster to the new Oracle (RAC, CRS,
Clusterware, OPS) release.
9. Restart Oracle (RAC, CRS, Clusterware, OPS) 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, there are slightly different steps. See section “Removing
Serviceguard Extension for RAC Without Removing Serviceguard”.
Use the following steps to remove the software from each node:
Online Node Reconfiguration:
1. Halt the cluster services on the node(s) to be removed. Edit the cluster ASCII file
to remove the nodes from which you removed SGeRAC, then re-apply the
configuration. The cluster remains up and running.
2. Issue the swremove command to remove the software.
Offline Node Reconfiguration:
1. Halt the cluster and remove the node from the configuration. If you intend to
continue running the SGeRAC cluster on the remaining nodes, edit the cluster
ASCII file to remove the nodes from which you removed SGeRAC, then re-apply
the configuration.
2. Optionally, restart the cluster on the remaining nodes.
3. Issue the swremove command to remove the software. If SGeRAC is being
deinstalled from more than one system, it should be removed from one system at
a time.
Optionally, after de-installing SGeRAC, you may use the swremove command to
de-install Serviceguard.
