HP XP P9500 Storage - Manual (Page 13)

NOTE:
•
Storage Administrator (Remote Copy) role access to the Remote Web Console Java applet
program is required to perform operations. Users without Storage (Remote Copy) role write
access can only view (Remote Copy) role information.
•
If the RAID Manager computer is not installed, contact HP Technical Support for information
on Continuous Access Journal Z configuration services.
Business Continuity Manager
Business Continuity Manager provides management of Continuous Access Journal Z software in
mainframe environments. Business Continuity Manager software automates Continuous Access
Journal Z operations (as well as operations for Business Copy Z and Continuous Access Synchronous
Z). Access to system performance metrics and thresholds provides problem avoidance and optimum
performance.
Overview of copy operations
The following sections describe initial and update copy operations including the underlying
operations, such as journal processing and differential data management.
Initial copy operation
The initial copy is executed when the primary storage system copies all the data in sequence in
the P-VOL directly to the S-VOL. Though journal volumes are not used during the initial copy, the
copy data in this operation is referred to as “base journal data.”
•
Creating pairs independently of journal activity results in the base journal data being copied
to the respective S-VOLs one at a time. This extends the time required for multiple initial copies.
•
An initial copy operation can be performed to establish the Continuous Access Journal Z pair
relationship — with no data copied between the volumes. This can be done when data in the
P-VOLs and S-VOLs are the same.
•
A volume pair can also be created using a Continuous Access Synchronous initial copy
operation. See
“Planning pair volumes” (page 27) for more information.
