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

Setting up replication using VVR on the secondary

site

To create objects for replication on the secondary site, use the vradmin command

with the addsec option. To set up replication on the secondary site, perform the

following tasks:

■ If you have not already done so, create a disk group to hold data volume, SRL,

and RVG on the storage on the secondary site.

■ Create volumes for the database and SRL on the secondary site.

See “Creating the data and SRL volumes on the secondary site” on page 327.

■ Edit the /etc/vx/vras/.rdg file on the secondary site.

See “Editing the /etc/vx/vras/.rdg files” on page 328.

■ Use resolvable virtual IP addresses that set network RLINK connections as

host names of the primary and secondary sites.

See “Setting up IP addresses for RLINKs on each cluster” on page 328.

■ Create the replication objects on the secondary site.

See “Setting up the disk group on secondary site for replication” on page 329.

Creating the data and SRL volumes on the secondary site

Note the following when creating volumes for the data and SRL:

■ The sizes and names of the volumes must reflect the sizes and names of the

corresponding volumes in the primary site.

■ Create the data and SRL volumes on different disks in the disk group. Use the

vxdisk -g diskgroup list command to list the disks in the disk group.

■ Mirror the volumes.

To create the data and SRL volumes on the secondary site

In the disk group created for the application database, create a data volume

of same size as that in primary for data; in this case, the rac_vol1 volume on

the primary site is 6.6 GB:

# vxassist -g oradatadg make rac_vol1 6600M nmirror=2 disk1 disk2
