NOTE:
Administrator or Continuous Access Journal write access to the Remote Web Console Java
applet program is required to perform these operations. Users without Administrator or
Continuous Access Journal write access can only view Continuous Access Journal information.
If the RAID Manager computer is not installed, contact your HP account team for information
on Continuous Access Journal configuration services.

RAID Manager

RAID Manager can be used to perform the same operations as the Remote Web Console GUI.
The operations can be run with RAID Manager using scripts.

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 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 25) for more information.
