3 Requirements and Restrictions for Universal Replicator
z/OS Operations
This chapter describes URz operations involving the XP disk array primary and secondary storage
systems, the remote copy connections between the primary/secondary storage systems, and the
host(s) at the primary and secondary sites, as well as the licensed URz remote console software.
System Requirements
URz operations involve the XP disk array primary storage systems and secondary storage systems
containing the primary and secondary data volumes, the remote copy connections between the
primary storage systems and secondary storage systems, the host(s) at the primary and secondary
sites, and the licensed URz remote console software. The URz system requirements are:
• primary subsystem: XP storage system with URz installed.
• secondary subsystem: XP storage system with URz installed.
Notes:
• URz can coexist with HP StorageWorks XP Continuous Access Journal in the same XP storage
system.
• The remote copy connection with the NAS interface is not supported.
• Remote copy connections − fibre channel (see Setting up Remote Copy Connections):
Multimode or single-mode optical fibre cables are required at both the primary storage
system and secondary storage system.
◦
◦ For distance up to 0.5 km, multimode optical shortwave fiber cables are required between
the primary storage system and secondary storage system.
◦ 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 distance up to 10 km, single optical long wave fiber cables are required between
the primary storage system and secondary storage system.
◦ For distances from 10 km to 30 km (6.2 to 18.6 miles), single-mode long wave Fibre
Channel interface cables with up to two switches are required.
◦ For distances greater than 30 km (18.6 miles), approved third-party channel extender
products and telecommunications lines are required. Long-distance URz solutions are
provided based on user requirements and workload characteristics.
• Supported mainframe host operating systems (OS):
XP disk array supports the following mainframe host operating systems (OS):
◦ MVS, OS/390, z/OS, VOS3, MSP-EX
◦ Optional error report communications (ERC) function requires MVS/DFP 3.2.0 or later.
◦ If the primary and/or secondary systems consist of several CPU complexes, a SYSPLEX
timer is required to provide a common time reference for the host I/O time-stamping
function.
Please contact your HP account team for the latest information on platform support for URz.
• A computer that runs XP Remote Web Console (XP Remote Web Console computer):
The XP Remote Web Console remote console software is required for XP URz operations. The
URz remote console software is a component of the XP Remote Web Console software. The
URz license key(s) are required to enable the URz option(s) on the XP storage system (see
Enabling the URz Option(s)). Separate license keys are required for each XP storage system.
