Hitachi TrueCopy for IBM z/OS User and Reference Guide (T5211-96001, June 2007)

3-2 Preparing for TrueCopy for z/OS Operations
Hitachi Universal Storage Platform V TrueCopy for IBM z/OS User’s Guide
System Requirements
TrueCopy for z/OS operations involve the USP V MCUs and RCUs containing
the main and remote volumes, the remote copy connections between the
MCUs and RCUs, the zSeries
®
and S/390 host(s) at the main and remote sites,
and the TrueCopy for z/OS software. The TrueCopy for z/OS system
requirements are:
• MCU: USP V storage system with TrueCopy for z/OS installed by using
license code. Note: For information on remote copy operations using the
TagmaStore USP/NSC storage system as an MCU, please refer to the Hitachi
TagmaStore USP/NSC TrueCopy for z/OS User and Reference Guide
(MK-94RD214).
Note: For important information about proper configuration for your
operational environment, refer to Appendix C.
• RCU: USP V storage system with TrueCopy for z/OS installed by using
license code. Note: TagmaStore USP/NSC storage system with TrueCopy for
z/OS installed can be used as an RCU connected to a USP V MCU. For
assistance with mixed storage system configurations, please contact your
Hitachi representative.
Note: TrueCopy for z/OS can coexist with TrueCopy (all copy modes) in
the same USP V storage system. Full fibre-channel support will allow
concurrent fibre-mode TrueCopy and TCz operations.
Note: The USP V storage systems may have additional installation
requirements (e.g., system option modes, DKC-F510I-32FS2, DKC-F515I-
MIX2, additional cache, etc.). For information on system option modes for
TrueCopy for z/OS, refer to Table 2-2.
• zSeries and S/390 host: MVS/DFP 3.2.0 + PTF, or VM/ESA
®
2.1.0 + PTF.
– Optional error recover procedure (ERP) functions require MVS/DFP 3.2.0
or later.
– ICKDSF R16 + PTF functions require VM/ESA 2.1.0 or later.
– If the primary and/or secondary system consists of several CPU
complexes, a SYSPLEX timer is required to provide a common time
reference for the host I/O time-stamping function.
• Remote copy connections – fibre channel:
– Multimode or single-mode optical fibre cables are required at both the
MCU and RCU.
– For distances from 0.5 km to 1.5 km (1,640 to 4,920 feet), multimode
shortwave fibre channel interface cables with up to two switches are
required.
– For distances from 10 km to 30 km (6.2 to 18.6 miles), single-mode
longwave fibre channel interface cables with up to two switches are
required.
