14 Hitachi TrueCopy z/OS for HP XP12000/XP10000 and SVS 200 storage systems
Other data duplication Features
In addition to TC390, the XP12000/XP10000 storage system provides several other data duplication
features that are described below. For more information about these features, contact your HP account
support representative.
HP XP Business Copy and Hitachi ShadowImage z/OS (SI390)
You can use HP StorageWorks XP Business Copy (BC) Software and SI390 data duplication features to set
up and maintain multiple copies of logical volumes within the same XP12000/XP10000. BC operations
for zSeries and S/390 data are performed using the SI390 through XP Command View Advanced Edition
Software or XP Remote Web Console and can also be managed using the TSO and/or ICKDSF
commands. BC operations for UNIX/PC server-based data are performed using the licensed BC software
through XP Command View Advanced Edition Software or XP Remote Web Console or the XP Raid
Manager software on the UNIX/PC server host.
The RAID-protected SI390 duplicates are created within the same XP12000/XP10000 at hardware
speeds. SI390 can be used in conjunction with TC390 to maintain multiple copies of critical data at your
primary and/or secondary (remote) sites. For more information on combining TC390 and SI390
operations, see ” Combining TrueCopy and ShadowImage ” on page 62.
Hitachi Extended Remote Copy
The Hitachi Extended Remote Copy (HXRC) feature of the XP12000/XP10000 is functionally compatible
with the industry-standard IBM Extended Remote Copy (XRC) host software function and is provided as a
program product. HXRC is also compatible with the DFSMS data mover that is common to the XRC
environment. HXRC operations are performed in the same manner as XRC operations, by issuing XRC TSO
commands from the host system to the XP12000/XP10000.
This chapter provides disk array-specific HXRC information (for example, SVP system option modes), but
does not cover XRC operations.
SVP option modes: For important information on XP12000/XP10000 SVP system option modes for HXRC,
see Table 3 on page 18.
16 session support: The XP12000/XP10000 must be configured with 3990-6E emulation (no 3380 LVIs)
and 256 LDEVs/SSID for 16 session (per disk array) support. APAR OW36948 must be applied. A disk
array power cycle is required when the SSID boundary is changed (64 => 256).
Device blocking, load balancing: For important information on HXRC device blocking support and load
balancing control, see ” HXRC device blocking and load balancing ” on page 216.
Changing from 3990 to 2105 or 2107: For important information and instructions on changing from 3990
to 2105 emulation for disk arrays with existing HXRC volumes, see ” CU emulation types ” on page 21.
HXRC operations, as well as TC390A operations, use additional cache to store the sidefile queue of
asynchronous recordsets. If you are maintaining HXRC pairs and TC390A pairs, verify that your
XP12000/XP10000 has adequate cache installed and available to support both asynchronous remote
copy workloads. Contact your HP account support representative to determine how much cache will be
needed for your disk array configuration.
NOTE: If the ANTX5123W console message is displayed during the RESUME operation for HXRC pairs,
the operation might be unsuccessful. In this case, you must perform the XDELPAIR operation to delete the
pairs, and then perform the XADDPAIR operation to create the pairs again.
NOTE: If the ANTA5107E (RC=9014, REAS=604, or REAS=608) console message is displayed
during the XADDPAIR operation, the HXRC PP option may not have been installed. Verify that the HXRC PP
option is installed and if not, install the HXRC PP option.
