Conditions for copy pair operations (basic versus advanced)

Available copy pair operations depend on the storage system type and volume status.

Basic operations

The following operations and storage system configurations are not supported for basic operations:

•

A create or delete operation for a copy group defined in a device group.

•

The storage system type is XP24000/XP20000 or HP StorageWorks P9500 and the copy pair is
a HAM copy pair.

NOTE:

For mainframe systems, basic operations require HP StorageWorks P9000 for Business Continuity
Manager Software (not P9000 mainframe agent).

Advanced operations

For open systems, the following storage system configurations support advanced operations:

•

The storage system is HP P9500, the target is not a copy group defined in a device group, and
the copy type is either Continuous Access Synchronous or Continuous Access Journal.

•

The storage system is XP12000/XP10000/SVS200 or XP24000/XP20000 and the copy type is
either Continuous Access Journal or Continuous Access.

For mainframe systems, change pair status operations might not be possible depending on volume
status.

•

Before performing a split operation, confirm that I/0 to the primary volume is not in progress. If
I/0 is in progress, the data on the secondary volume might be incomplete.

•

During a planned stop (when the primary and secondary volumes are being switched), a delete
operation cannot be executed.
