Storage system conditions for pair configuration definition

” on page 148.

TIP:

Use the latest versions of the storage system's microprogram and P9000 RAID Manager.

CAUTION:

While a copy pair configuration definition is being created, do not use storage system operation
management software, such as Device Manager, P9000 RAID Manager, Remote Web Console, or
HP StorageWorks P9000 for Business Continuity Manager Software, to perform concurrent operations
on a volume, copy group, or copy pair specified in that definition. Using this software may cause
errors when Replication Manager executes tasks.
