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 london.
Assumptions:
These examples assume that the Primary seattle and Secondary london have a disk group named hrdg with enough free space to create the VVR objects mentioned in the example.
Examples 1, 2, 3, 4, and 5 assume that the Primary data volumes have been set up and contain data.
The examples assume that the /etc/vx/vras/.rdg file on the Secondary host contains the Primary diskgroup ID. Ensure that each disk group ID entry in the .rdg file appears on a separate line. A Secondary can be added to an RDS only if the /etc/vx/vras/.rdg file on the Secondary host contains the Primary disk group ID. Use the vxprint -l diskgroup command to display the disk group ID of the disk group hrdg, which is being used.
Consider the following in each example:
In the examples, each data volume is 4 GB; the Primary and Secondary SRL are 4 GB each.
