Adding Serviceguard Extension for RAC to an Existing Cluster
If you have already installed Serviceguard and are running a Serviceguard cluster, use
the following steps to add SGeRAC:
NOTE: All nodes in the cluster must be either all SGeRAC nodes or Serviceguard
nodes. SGeRAC cluster must have SGeRAC software installed on all nodes.
1. Halt the cluster.
2. Use swinstall to install SGeRAC on each node.
3. Modify the cluster configuration ASCII file as necessary for RAC use, add
OPS_VOLUME_GROUP if required, then run the cmapplyconf command.
4. Reboot each node.
5. Restart the cluster.
Removing SGeRAC
To remove your software, run the SD-UX swremove command.
NOTE: If you are removing SGeRAC and wish to continue using the cluster as an
Serviceguard cluster, there are slightly different steps. See section “Removing
Serviceguard Extension for RAC Without Removing Serviceguard”.
Use the following steps to remove the software from each node:
Online Node Reconfiguration:
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
