The examples in this section explain how to use Veritas Volume Replicator (VVR) to set up a simple VVR configuration under different situations. The examples explain how to set up a VVR configuration with one Secondary and hence one RLINK; however, VVR enables you to configure and set up configurations with multiple Secondaries. The examples give the steps to replicate from the Primary host
seattle to the Secondary host
londonhave a disk group named
hrdgwith enough free space to create the VVR objects mentioned in the example.
rdgfile on the Secondary host contains the Primary diskgroup ID. Ensure that each disk group ID entry in the
.rdgfile appears on a separate line. A Secondary can be added to an RDS only if the
rdgfile on the Secondary host contains the Primary disk group ID. Use the
diskgroupcommand to display the disk group ID of the disk group
hrdg, which is being used.
Consider the following in each example:
The data volumes on the Secondary must have the same names and sizes as the data volumes on the Primary.
The name of the Storage Replicator Log (SRL) on the Secondary must be the same as the name of the SRL on the Primary.
The SRL must be created on disks that do not have other volumes on them.
The data volumes and SRL must be mirrored.
In the examples, each data volume is 4 GB; the Primary and Secondary SRL are 4 GB each.
The examples in this chapter use the following names:
