Continuous Access Journal Z - HP StorageWorks P9000 User Manual

Access Synchronous Z M-VOL may take extra time depending on the time for copying process
of the Business Copy Z pair.
The Quick Restore operation can be performed on a Business Copy Z pair when the Continuous
Access Synchronous Z pair is suspended.
NOTE: When using PPRC, you cannot distinguish between the Split status and the V-Split status.
If you use PPRC to perform operations on volumes shared by Continuous Access Synchronous Z
and Business Copy Z, you need to do one of the following:
Specify MPS00 for the PRIM parameter of the CSUSPEND command to perform Steady Split.
In this case the pair status will not be V-Split.
Use the Remote Web Console to confirm whether the pair status is Split or V-Split.
For details, see the section on sharing volumes with Business Copy Z in the HP StorageWorks
P9000 Continuous Access Synchronous for Mainframe Systems User Guide.

When you query pair status for Business Copy Z and Continuous Access Journal Z shared
volumes using PPRC, the system reports Business Copy Z status. Use Business Continuity

A Continuous Access Journal Z secondary volume that is also the Business Copy Z source
volume can be configured so that Business Copy Z backup copies are made at a specific time
using the At-Time Split operation. For more information, see "Using At-Time Split function when
combining Continuous Access Journal Z with Business Copy Z" in the HP StorageWorks P9000
Continuous Access Journal User Guide.
For more information, see Appendixes A and C in the HP StorageWorks P9000 Continuous Access
Journal for Mainframe Systems User Guide.
If you specify the S-VOL of Continuous Access Journal Z as the S-VOL of Business Copy Z, you can
configure the time to back up the S-VOL of Continuous Access Journal Z using the At-Time Split
function of Business Continuity Manager. This is called Split processing (see
The time at which you execute Split processing is called the Split time.
