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 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.
