Chapter 1 21
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 Serviceguard Extension for RAC, then re-apply the
configuration.
2. Optionally, restart the cluster on the remaining nodes.
3. Issue the swremove command to remove the software. If
Serviceguard Extension for RAC is being deinstalled from more than
one system, it should be removed from one system at a time.
Optionally, after de-installing Serviceguard Extension for RAC, you may
use the swremove command to de-install Serviceguard.
Removing SGeRAC Without Removing Serviceguard
If you want to remove SGeRAC and return the cluster to use as an
Serviceguard cluster, use the following steps:
1. Halt the cluster.
2. Use swremove to remove Serviceguard Extension for RAC from each
node.
3. Reboot each node.
4. Edit the cluster configuration ASCII file to remove any
OPS_VOLUME_GROUP entries, then run the cmapplyconf command.
5. Restart the cluster.
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. Log messages from these daemons
appear in /var/adm/syslog/syslog.log.
