Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

Modifying the VCS Configuration on the Secondary Site
The following are highlights of the procedure to modify the existing VCS
configuration on the secondary site:
■ Add the log owner and RVG service groups.
■ Add a service group to manage the application database and the supporting
resources.
■ Define the replication objects and agents, such that the cluster at the secondary
site can function as a companion to the primary cluster.
The following steps are similar to those performed on the primary site.
To modify VCS on the secondary site
1
Log into one of the nodes on the secondary site as root.
2
Use the following command to save the existing configuration to disk, and
make the configuration read-only while making changes:
# haconf -dump -makero
3
Use the following command to make a backup copy of the main.cf file:
# cd /etc/VRTSvcs/conf/config
# cp main.cf main.orig
4
Use vi or another text editor to edit the main.cf file. Edit the CVM group on
the secondary site.
Review the sample configuration file after the SFCFS installation to see the
CVM configuration.
In our example, the secondary site has clus2 consisting of the nodes mercury
and jupiter. To modify the CVM service group on the secondary site, use the
CVM group on the primary site as your guide.
5
Add a failover service group using the appropriate values for your cluster
and nodes. Include the following resources:
■ RVGLogowner resource. The node on which the group is online functions
as the log owner (node connected to the second cluster for the purpose of
replicating data).
■ IP resource
■ NIC resources
Example RVGLogowner service group:
