CVM master node needs to assume the logowner role for VCS managed VVR resources

If you use VCS to manage RVGLogowner resources in an SFCFSHA environment or an SF Oracle RAC environment, Veritas recommends that you perform the following procedures. These procedures ensure that the CVM master node always assumes the logowner role. Not performing these procedures can result in unexpected issues that are due to a CVM slave node that assumes the logowner role.

For a service group that contains an RVGLogowner resource, change the value of its TriggersEnabled attribute to PREONLINE to enable it.

To enable the TriggersEnabled attribute from the command line on a service group that has an RVGLogowner resource

On any node in the cluster, perform the following command:
```
# hagrp -modify RVGLogowner_resource_sg TriggersEnabled PREONLINE
```
Where RVGLogowner_resource_sg is the service group that contains the RVGLogowner resource.

To enable the preonline_vvr trigger, do one of the following:

If preonline trigger script is not already present, copy the preonline trigger script from the sample triggers directory into the triggers directory:
# cp /opt/VRTSvcs/bin/sample_triggers/VRTSvcs/preonline_vvr /opt/VRTSvcs/bin/triggers/preonline
Change the file permissions to make it executable.
If preonline trigger script is already present, create a directory such as /preonline and move the existing preonline trigger as T0preonline to that directory. Copy the preonline_vvr trigger as T1preonline to the same directory.
If you already use multiple triggers, copy the preonline_vvr trigger as TNpreonline, where TN is the next higher TNumber.
