Preparing for Continuous Access XP operations

System requirements

Continuous Access XP operations involve MCUs and RCUs containing primary and secondary volumes,
remote copy connections between MCUs and RCUs, UNIX and/or PC server hosts at primary and remote
sites, and Continuous Access XP. You can use the Command View XP management station or XP Remote
Web Console to manage MCUs and RCUs. Continuous Access XP system requirements are:
• MCU: Disk array with Continuous Access XP installed.
• RCU: Disk array with Continuous Access XP installed.
• UNIX-based and/or PC server platforms: The disk array supports Continuous Access XP
operations for a variety of UNIX and PC-server platforms, including the Sun® Solaris®, IBM®
AIX®, HP-UX®, and Windows NT® platforms. Contact your HP account support representative
for the latest information on array platform support for Continuous Access XP.
• Remote copy connections – Fibre Channel:
• Multimode optical fibre cables at both the MCU and RCU
• For distances from 0.5 km to 1.5 km (1640 to 4920 feet), multimode shortwave Fibre Channel
interface cables with up to two switches are required (tor 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, approved third-party channel extender (or DWDM) products
and telecommunications lines
NOTE:
All fibre-channel remote copy activities between two XP/SVS200 subsystems (i.e., Continuous
Access XP Sync and Async, remote replication for z/OS® Sync and Async) can share the same
remote copy connections.
• Command View XP management station or XP Remote Web Console: Web-based GUI for
Continuous Access XP and license keys. You can access XP Remote Web Console directly from
the disk array or through Command View XP.
• About the license of HP StorageWorks Continuous Access XP Asynchronous: If you want to use
HP StorageWorks Continuous Access XP Asynchronous, you must install not only a license for
HP StorageWorks Continuous Access XP Asynchronous but also a license for HP StorageWorks
Continuous Access XP . Also, the license capacity of HP StorageWorks Continuous Access XP
and the license capacity of HP StorageWorks Continuous Access XP Asynchronous must satisfy
the following equation: License capacity of HP StorageWorks Continuous Access XP
capacity of HP StorageWorks Continuous Access XP Asynchronous
NOTE:
You must operate Command View XP or XP Remote Web Console in Modify mode to perform Continuous
Access XP operations. In view mode, you can only view Continuous Access XP information.

Requirements and restrictions

Continuous Access XP has the following requirements and restrictions:
• One-to-one volume copy operations
• Logical unit (LU) type (also called device emulation or type)
• Consistency groups
• Accessing Continuous Access XP P-VOLs and S-VOLs
