In case of an L1 pair, you can use 0, 1, or 2 as an MU number. In case of an L2 pair, you
can use 1 or 2 as an MU number.
•
Number of S-VOLs per one P-VOL
You can assign up to three S-VOLs to one P-VOL when creating an L1 pair. When creating
an L2 pair (leaf pair), you can assign up to two S-VOLs to one P-VOL. However, you cannot
assign two or more P-VOLs to one S-VOL.

Maximum number of pairs
Up to 16,384 XP Business Copy pairs can be created (when P-VOLs and S-VOLs are in a
one-to-one relationship). If the LUSE volumes are included in XP Business Copy pairs, the
maximum number of pairs decreases.
If the above requirements are fulfilled, the following volumes cannot be used for creating XP Business
Copy pairs.

XP Business Copy Software Requirements
To use XP Business Copy, all storage system hardware, microcode, and software required for XP
Business Copy operations must be installed and enabled. You also need to purchase a license key
for XP Business Copy and install it on the storage system. For detailed information about the license
key and software installation, see the HP StorageWorks XP24000/XP20000 Remote Web Console
User Guide.
Note that you must operate Remote Web Console in modify mode to perform XP Business Copy
operations. Users in view mode can only view XP Business Copy information, but they cannot
create new pairs or change the pair status. For information about how to set up and use the Remote
Web Console computer, see the HP StorageWorks XP24000/XP20000 Remote Web Console
User Guide.
License Requirements
XP Business Copy license capacity will be required for XP Business Copy P-VOLs, S-VOLs, and
reserved volumes. In addition, P-VOLs and pool volumes that are used by XP Snapshot will require
the XP Business Copy license capacity. You need to make sure that the XP Business Copy license
capacity will be larger than the total capacity of these volumes when you decide the XP Business
Copy license capacity.
When a volume is used for multiple purposes, only the capacity of this volume is added to the total
volume capacity. There is no need to multiply the capacity of this volume by the number of purposes
it is used for. For example, if you specify a volume as an S-VOL, and use it as a reserved volume
