Requirements and Restrictions for URz
URz has the following requirements and restrictions:
• System requirements (see the next section)
• Disk track format
• One-to-one volume copy operations
• Duplicate VOLSER
• Volume type
• Journal group
• Accessing URz primary data volumes and secondary data volumes
• Cache and NVS
• Duplicate volume
System Requirements
URz operations involve the USP V 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 storage system: USP V storage system with URz installed.
• secondary storage system: USP V storage system with URz installed.
Note: URz can coexist with UR in the same USP V storage system.
Note: The remote copy connection with the NAS interface is not supported.
• Remote copy connections – fibre channel (see section 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.
