The following figure shows a typical setup of volumes for an failover cluster with Volume Replicator configuration with a database application. The example has one disk group for the application on each site.
If there are more application disk groups in your configuration, note that each disk group requires an additional Replicator Log volume. In the procedures described in this chapter, the Replicator Log volume will be created later; but you will need to allow sufficient disk space for the number of Replicator Log volumes required by your configuration.
The quorum volume is not replicated to the second site and is in a separate disk group. It has to be created on each site and functions only on that site. The minimum number of disks for the mirrored quorum is two disks. Veritas recommends using three disks for the mirrored quorum for additional redundancy.
Do not use the following types of volumes for the data and Replicator Log volumes; Volume Replicator does not support these types of volumes:
Storage Foundation (software) RAID 5 volumes
Volumes with the Dirty Region Log (DRL)
Volumes with a comma in their names
For the Replicator Log volume, in addition to the above types also make sure that the volume does not have a DCM.
