Hitachi TrueCopy z/OS for HP
XP12000/XP10000
and SVS 200 storage systems
Hitachi TrueCopy features
Hitachi TrueCopy (TC390) creates and maintains remote copies of the S/390 data stored on HP
XP12000/XP10000 and SVS 200 storage systems for data duplication, backup, and disaster recovery
purposes. TC390 provides synchronous and asynchronous copy modes to accommodate a wide variety of
user requirements and data copy/movement scenarios. TrueCopy Asynchronous (TC390A) provides a
superior hardware-based solution for data duplication, data migration, remote copy, and disaster recovery
tasks.
NOTE:
This manual refers to the z/OS operating system, but other operating systems are also supported.
Contact your HP account support representative for a list of supported operating systems.
NOTE:
In this chapter, the term TC390 refers to both TrueCopy Synchronous and TrueCopy Asynchronous
unless otherwise noted.
TC390 operations are nondisruptive, allowing the main (primary) volume of each TC390 pair to remain
online to all hosts for both read and write I/O operations. After operations have been established, TC390
operations continue unattended to provide continuous data backup. For serial interface connection, TC390
operations can be performed across distances of up to 43 km (26.7 miles) using standard ESCON
support. For Fibre Channel connection, TC390 operations can be performed across distances of up to
30 km (18.6 miles) using single-mode longwave optical fibre cables in a switch configuration.
Long-distance solutions are provided, based on user requirements and workload characteristics, using
approved channel extenders and communication lines. TC390 is a key component of HP solutions and
service offerings.
After hardware connectivity between XP12000/XP10000 (or between XP12000/XP10000 and other XP
disk arrays) is established, TC390 operations can be performed from XP Command View Advanced
Edition or XP Remote Web Console and/or from the zSeries and S/390 system software for maximum
usability:
•
TC390 running under XP Command View Advanced Edition Software or XP Remote Web Console
displays detailed TC390 information and performs all TC390 operations. In the event of a system
failure or disaster at the main site, the TC390 software also simplifies and expedites disaster recovery
procedures. For operating systems that do not support Peer-to-Peer Remote Copy (PPRC) or ICKDSF
PPRCOPY commands, TC390 operations are performed using XP Command View Advanced Edition
Software or XP Remote Web Console.
•
TC390 is functionally compatible with industry-standard IBM Peer-to-Peer Remote Copy (PPRC) host
software functions. PPRC TSO commands (or ICKDSF PPRCOPY commands) combined with disaster
recovery PTFs may be used to perform TC390 and disaster recovery operations on XP12000/XP10000
storage system. TC390 supports the PPRC/Dynamic Address Switching (P/DAS) host software function
so you can use TC390 to relocate volumes nondisruptively. TC390 also supports the PPRC CGROUP
TSO command, which is used with IBM’s Geographically Dispersed Parallel Sysplex (GDPS) service
offering.
TC390 can be performed in conjunction with ShadowImage (SI390) (see ”
” on page 14) to provide multiple internal copies of TC390 volumes. TC390 also supports the
Virtual LVI/LUN and Cache LUN XP features of the XP12000/XP10000, ensuring that all zSeries and
S/390 user data can be protected by TC390 remote copy operations. For more information on
combining TC390 with other data management features, see ”
