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

Create the volume for the SRL, using the same name and size of the equivalent

volume on the primary site. Create the volume on different disks from the

disks for the database volume, but on the same disk group that has the data

volume:

# vxassist -g oradatadg make rac1_srl 1500M nmirror=2 disk4 disk6

Editing the /etc/vx/vras/.rdg files

Editing the /etc/vx/vras/.rdg file on the secondary site enables VVR to replicate

the disk group from the primary site to the secondary site. On each node, VVR

uses the /etc/vx/vras/.rdg file to check the authorization to replicate the RVG on

the primary site to the secondary site. The file on each node in the secondary site

must contain the primary disk group ID, and likewise, the file on each primary

system must contain the secondary disk group ID.

To edit the /etc/vx/vras/.rdg files

On a node in the primary site, display the primary disk group ID:

# vxprint -l diskgroup

.....

On each node in the secondary site, edit the /etc/vx/vras/.rdg file and enter

the primary disk group ID on a single line.

On each cluster node of the primary cluster, edit the /etc/vx/vras/.rdg file

and enter the secondary disk group ID on a single line.

Setting up IP addresses for RLINKs on each cluster

Creating objects with the vradmin command requires resolvable virtual IP

addresses that set network RLINK connections as host names of the primary and

secondary sites.

To set up IP addresses for RLINKS on each cluster

For each RVG running on each cluster, set up a virtual IP address on one of

the nodes of the cluster. These IP addresses are part of the RLINK.

The example assumes for the cluster on the primary site:

■ The public network interface is lan0:1

■ The virtual IP address is 10.10.9.101
