Prerequisites for a fire drill in a Volume Replicator environment
Before you run the Fire Drill Wizard make sure that you meet both the general requirements and the specific requirements for your replication environment.
General requirements are covered separately.
Make sure that the following additional prerequisites are met before configuring and running a fire drill in a Volume Replicator environment:
-
The primary and secondary sites must be fully configured with Volume Replicator replication and the global cluster option.
-
The secondary system where you plan to run the fire drill must have access to the replicated volumes.
-
On the secondary site, empty disks must be available with enough disk space to create snapshot mirrors of the volumes. Snapshot mirrors take up the same amount of space as the original volumes. In addition, two disk change object (DCO) volumes are created for each snapshot mirror, one for the source volume and one for the snapshot volume. The two DCO volumes must be on different disks. Allow 2 MB additional space for each DCO volume.
The empty disks must be in the same disk group that contains the RVG. If the disk group does not have empty disks available, you must use the VEA to add the disks to the disk group before you run the wizard. The secondary system must have access to the disks or LUNs.
-
All disk groups in the service group must be configured for replication. The Fire Drill wizard does not support a Volume Replicator configuration in which disk groups are excluded from replication. However, you can exclude individual volumes within a disk group from replication.
