Table 8 describes Continuous Access XP Journal suspension conditions and indicates which CU detects the
condition and which pairs are suspended. See ” Displaying the History Operation pane ” on page 128 for
troubleshooting information for Continuous Access XP Journal suspension conditions.
Continuous Access XP Journal operations requirements and restrictions
System requirements
Continuous Access XP Journal operations involve XP10000/XP12000 primary and secondary disk arrays
containing the primary and secondary volumes, the remote copy connections between the primary and
secondary disk arrays, the hosts at the primary and remote sites, and the licensed Continuous Access XP
Journal. The Continuous Access XP Journal system requirements are:
• Primary disk array: local disk array with Continuous Access XP Journal installed
• Secondary disk array: local disk array with Continuous Access XP Journal installed
NOTE: Continuous Access XP Journal can coexist with Universal Replicator for z/OS in the same
local disk array.
• Remote copy connections: fibre channel (see ” Remote copy connections ” on page 21)
• Multimode or single-mode optical fibre cables are required at the primary and secondary disk
arrays.
• For distance up to 0.5 km, multimode optical shortwave fiber cables are required between the
primary and secondary disk arrays.
• 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 longwave fiber cables are required between the primary
and secondary disk arrays.
• 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.
• For distances greater than 30 km (18.6 miles), approved third-party channel extender products and
telecommunications lines are required. Long-distance Continuous Access XP Journal solutions are
provided based on user requirements and workload characteristics.
• Host platforms
The XP10000/XP12000 supports Continuous Access XP Journal operations for a variety of
UNIX-based and PC server platforms, including HP-UX 11.0, HP-UX 11i, Sun® Solaris® 9, Windows®
