About changing copy pair status

Replication Manager allows you to change the copy pair status in open and mainframe systems. Pair
status change operations may be necessary to resume copy operations after recovery from an error
or unexpected pair status changes.

For open systems, you can perform the split, resync, restore, create and delete operations when the
storage system type is XP12000/XP10000/SVS200 or XP24000/XP20000. You can perform the
split, resync, and restore operations when the storage system is XP12000/XP10000/SVS200,
XP24000/XP20000, or XP1024/XP128.

For mainframe systems, you can perform the delete, split, resync and restore operations when the
storage system type is XP12000/XP10000/SVS200 or XP24000/XP20000. The create operation
is not supported. The above copy pair status change operations can be performed only when HP
StorageWorks P9000 for Business Continuity Manager Software is used. These operations cannot
be performed when P9000 mainframe agent is used.

The pair status conditions where the current pair status can be changed differ depending on the copy
type and the copy pair state when the operation is specified. They also differ depending on whether
the target is a single or multiple copy pairs and whether the target is a copy group. For information,
see the following:

• Pair status transitions (when the target is a single or multiple copy pairs)

, page 218

• Pair status transitions (when the target is a copy group)

CAUTION:

While a copy pair configuration definition is being edited, 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. Doing so may cause errors when
Replication Manager executes tasks.
