2 Preparing for External Storage XP operations
This chapter describes requirements, preparations, and notes for External Storage XP. This chapter also
describes the HP StorageWorks products you can use with External Storage XP.
System requirements
External Storage XP operations involve the local array, a storage array used as an external array, and the
licensed External Storage XP feature enabled on Command View XP or XP Remote Web Console. System
requirements for External Storage XP are:
• Local array (first array)
Install and enable all hardware and microcode required for External Storage XP operations in the
local array.
CAUTION: Before installing and enabling the hardware and microcode, see ”Managing cache
with external storage” on page 45 for instructions.
NOTE: Currently only an XP12000/XP10000/SVS200 can be used as a local array.
• External array (second array)
You also need a second storage device, called an external array in this user guide. For more
information, see ”Storage arrays that can be connected as external arrays” on page 15.
• HP StorageWorks Command View XP (running on a user-supplied Windows®-based PC) or XP Remote
Web Console
For instructions on installing and using Command View XP or XP Remote Web Console, see the
HP StorageWorks Command View XP user guide for XP Disk Arrays or the HP StorageWorks XP Remote
Web Console user guide for XP12000/XP10000/SVS200.
NOTE: You must run Command View XP or XP Remote Web Console in Modify mode to perform
External Storage XP operations. In View mode, you can only view External Storage XP information.
• External Storage XP
Enable the licensed External Storage XP feature in Command View XP or XP Remote Web Console.
Storage arrays that can be connected as external arrays
Table 2 lists storage arrays that can be connected as external arrays. Notes about the appearance of each
storage array in this document and in External Storage XP panes are also listed.

Storage array Notes
HP StorageWorks XP12000 Disk Array • In External Storage XP panes, the array appears as
“12000”.
• Alternate paths are in Multi mode (meaning that
dynamic load balancing across multiple active paths
is enabled).
HP StorageWorks XP10000 Disk Array • In External Storage XP panes, the array appears as
“10000”.
• Alternate paths are in Multi mode.
