For best results, store metafiles in a volume belonging to an SQL Server resource group so that, even
if an SQL Server cluster resource fails over, the metafiles are failed over with the resource group.
The following figure shows a sample location for metafiles in an active/standby (or active/passive)
cluster configuration.

Using a cluster configuration
Do not register the service resources of multiple SQL Server instances into a single cluster group.
Software that should not be used during replica operations
There are several tools and applications that can interfere with replica operations and should not be
run while performing backups and restores. Applications that use the primary or secondary volumes
can prevent P9000 RAID Manager from operating properly, interfere with mount/unmount operations,
and cause data inconsistencies. Such applications include:
Disk management tools
CHKDSK command
Disk de-fragmentation tools
Performance logging
Anti-virus programs
Programs that track directories and files in the drive (Index service, DLC service, and so on.)
Applications that carry out disk operations (backup products other than Application Agent, and
so on)
Veritas Enterprise Administrator
These applications might be executed from services in the background. Please adjust the startup times
so that processing of these applications does not conflict with replica operations.
