HP Serviceguard Version A.11.20 Release Notes, April 2011

Serviceguard for instructions in this case. See “About Device Special Files (DSFs)” (page 32) of
these Release Notes for more information about agile addressing.
Upgrading from an Earlier Release if You Are Not Using Rolling Upgrade (Non-Rolling
Upgrade)
If your cluster does not meet the requirements for a rolling upgrade, or you decide not to use rolling
upgrade for some other reason, you must bring down the cluster (cmhaltcl) and then upgrade
Serviceguard and HP-UX on the nodes. See Appendix D of the Managing Serviceguard manual.
You can perform a non-rolling upgrade (that is, an upgrade performed while the cluster is down)
from any HP-UX/Serviceguard release.
Uninstalling Serviceguard
To uninstall the Serviceguard software, run the SD-UX swremove command. Before removing
software, note the following:
1. Serviceguard must be halted (not running) on the node from which the swremove command
is issued.
2. The system from which the swremove command is issued must be removed from the cluster
configuration. (If the node is not removed from the cluster configuration first, swremove will
cause the current cluster to be deleted.)
3. The swremove command should be issued from one system at a time. That is, if Serviceguard
is being de-installed from more than one system, it should be removed from one system at a
time.
If a zero-length binary configuration file (/etc/cmcluster/cmclconfig) is left your system
you should remove it.
