2-12 About TrueCopy for z/OS Operations
Hitachi Universal Storage Platform V TrueCopy for IBM z/OS User’s Guide
USP V TrueCopy Software
The USP V program product includes TrueCopy for z/OS and TrueCopy. The
USP V Storage Navigator software communicates with the SVP of the USP V
via defined TCP/IP connections. For further information on USP V Storage
Navigator's operations, please refer to the Storage Navigator User's Guide
(MK-96RD621), or contact your Hitachi account team.
If you plan to use PPRC to perform TCzA operations, you must use the
TrueCopy for z/OS software to add the consistency groups and select the
desired group options and async options before you can add any TCzA pairs.
These functions can only be performed using the USP V Storage Navigator
software (or SVP*). Once the groups and async options have been configured,
PPRC commands can be used to establish and manage TCzA pairs.
If you will be using the USP V Storage Navigator software to perform TrueCopy
for z/OS operations (instead of PPRC), the MCU of each TrueCopy for z/OS pair
must be LAN-attached to the USP V Storage Navigator computer. You should
also attach all RCUs to a USP V Storage Navigator computer on a separate LAN
at the remote site. Having a separate LAN at the remote site enables you to
access the RCUs and TrueCopy for z/OS R-VOLs and perform TrueCopy for
z/OS operations at the remote site in the event that the main site is not
available (e.g., due to disaster). If you need to perform TrueCopy for z/OS
operations in the reverse direction from the remote site to the primary site
(e.g., disaster recovery), the TrueCopy for z/OS software at the remote site
simplifies and expedites this process.
*Note: For information on TrueCopy for z/OS Async configuration services,
please contact your Hitachi account team.
