HP Serviceguard A.11.20 Release Notes, September 2012

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.
