Abstract
This guide explains how to use Hitachi ShadowImage™ for Mainframe to create nondisruptive, high-speed copies of information
stored by mainframe hosts on HP StorageWorks XP24000/XP20000 Disk Arrays. Topics include preparing for, performing,
and troubleshooting ShadowImage for Mainframe operations using the Remote Web Console web client, PPRC host functions,
and XP for Business Continuity Manager Software. The intended audience is a storage system administrator or authorized
service provider with independent knowledge of HP StorageWorks XP storage systems, Remote Web Console, and mainframe
host software.

If you use the HP StorageWorks DKA Encryption License Key, you can create a ShadowImage for Mainframe pair by using an encrypted volume and a non-encrypted volume. For example, you can create the pair specifying an encrypted volume as the S-VOL and a non-encrypted volume as the T-VOL.

    Figure 3 Update Copy Operation CAUTION: Even if the copy operation is completed without any host I/O, the data in the S-VOL and the data in the T-VOL may not be the same. Whether the S-VOL and the T-VOL have the same data depends on the condition of the storage system.

    The operation for splitting all the pairs in the same CTG is similar to the operation for splitting pairs when a copy group is specified by using XP for Business Continuity Manager Software™. However, the operation for splitting pairs in a CTG works in Quick Split, so you cannot specify Steady Split.

Figure 7 Backward Pairresync Operations The S-VOL remains fully accessible during a normal/quick resync operation, but becomes inaccessible to all hosts during a reverse copy or quick restore operation. When reverse copy or quick restore is in progress, you cannot perform, add, split, or resync pair for any other pair that shares the same S-VOL (delete pair and suspend pair are allowed).

    T-VOL to the S-VOL. This ensures that the S-VOL and T-VOL are properly resynchronized in the desired direction, and also greatly reduces the time needed to resynchronize the pair. Pairresync for suspend pair When a normal/quick resync operation is performed on a suspended pair, the XP storage system copies all data on the S-VOL to the T-VOL, since all S-VOL tracks were flagged as difference data when the pair was suspended.
  • Page 21 Figure 8 ShadowImage for Mainframe Pair Status Transitions If a volume is not assigned to an SIz pair, its status is simplex. Select the simplex volumes for S-VOL and T-VOL to create an SIz pair. When you create an SIz pair, the initial copy operation starts. During the initial copy operation, the status of the S-VOL and T-VOL changes to pending.
