Serviceguard Extension for RAC Version A.11.19 Release Notes (May 2010)

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, and 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, and 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 de-installed 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.

Removing Serviceguard Extension for RAC Without Removing Serviceguard

If you want to remove SGeRAC and return the cluster to use as a Serviceguard cluster, use the following

steps:

1. Halt the cluster.

2. Use swremove to remove SGeRAC 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. For cmgmsd, the core dump location

is in /var/adm/cmcluster/cmgmsd. By default, log messages from these daemons appear in /

var/adm/syslog/syslog.log.
