Serviceguard Extension for RAC Version A.11.18 Release Notes, 5th Edition, October 2008

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.

Troubleshooting Tips
The core dump locations for the cluster manager and shared logical volume manager daemons
are in /var/adm/cmcluster and /etc/lvmconf respectively. For cmgmsd, the core dump
location is in /var/adm/cmcluster/cmsgmsd. By default, log messages from these daemons
appear in /var/adm/syslog/syslog.log.
