Before you configure the fire drill service group, ensure that the following pre-requisites are met:
Make sure the application service group is configured with a SRDF resource.
Make sure the infrastructure to take appropriate snapshots (mirror/clone/snap) is properly configured on the target arrays.
If you plan to run a fire drill on SRDF/A devices, you must have a TimeFinder/CG license.
When you use the Gold or Silver configuration, make sure TimeFinder for SRDF is installed and configured at the target array.
When you take snapshots of R2 devices, consider the following:
For TimeFinder/Mirror, BCV devices must be associated with and attached to the RDF2 device group or composite group, and fully established and synchronised with the R2 devices.
For TimeFinder/Clone, BCV or target devices must be associated with the RDF2 device group or composite group.
For TimeFinder/Snap, or space-optimized snapshots, the VDEV and SAVE devices must be associated with the device group or composite group for which you want to run the fire drill using space-optimized snapshots. Ensure that the SAVE pool that is defined in the SavePoolName attribute exists and that the SAVE devices are enabled in the SAVE pool.
When you take snapshots of non-replicated VxVM disk groups residing on Symmetrix devices, create a Symmetrix device group with the same name as the VxVM disk group. The device group must contain the same devices as in the VxVM disk group and additionally, have the same number of BCVs or target devices associated.
For non-replicated devices:
If you plan to run a fire drill using space-optimized snapshots, you must have a TimeFinder/Snap license.
Make sure that the VDEV devices and SAVE devices are associated with the device group or composite group for which you want to run fire drill using space-optimized snapshots.
Make sure that the SAVE pool as specified by SavePoolName attribute exists prior to running fire drill using space-optimized snapshots.
Make sure that the copy sessions are not created for the device or composite group prior to running fire drill with space-optimized snapshots.
Make sure that the SRDF mode of replication is set to Synchronous prior to running fire drill using space-optimized snapshots and clones. This is because EMC does not support creation of TimeFinder/Snap and TimeFinder/Clone copy sessions for RDF2 device, if the SRDF mode of replication is set to Asynchronous.
The secondary system where you plan to run the fire drill must have access to the replicated volumes.
