HP Hitachi ShadowImage for Mainframe User Guide (T5213-96032, November 2011)

If you use the HP 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. In
this case, data in the encrypted S-VOL will be copied as non-encrypted data in the non-encrypted
T-VOL.

Feature Highlights
CTGs. For XP disk array storage systems, the ShadowImage for Mainframe software
consistency-group function allows a user-defined group of ShadowImage for Mainframe volume

method creates a consistent point-in-time copy of an entire system, database, or any related sets
of volumes—a technique that can replicate data between a primary system and secondary systems
anywhere in the world, with full data integrity.
