on permitted copy types for copy pair configuration definitions for different storage system types, see

“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.

Copy pair configuration conditions

You can use the Pair Configuration Wizard to define a copy pair configuration that satisfies the

conditions listed in the following table. If the defined configuration does not satisfy these requirements

(or exceeds the documented limits), an error occurs during task execution, even if the wizard finishes

normally.
