86 External Storage XP for the XP10000/XP12000
Description for Characteristic2
When the connected external disk array is an EVA disk array, LUNs are displayed as Characteristic in
External Storage XP’s panes.
If you search for logical volumes by specifying the WWN that indicates EVA Port A in the configuration,
such as in Figure 45 , logical volumes named LUN 1 and LUN 2 are found for both HostGroup-1 and
HostGroup-2. In this case, two different logical volumes with the same name, such as LUN 1 and LUN 2,
are found as logical volumes that can be connected from EVA Port A, but you can only tell which LUN 1
and LUN 2 belong to HostGroup-1 or HostGroup-2 by examining the Characteristic field.
In the configuration in
Figure 45 , you can identify logical volumes by referring to Characteristic2 in
External Storage XP’s panes. The first 32 characters of Characteristic2 indicate the World Wide LUN
Name found on the EVA disk array. You can identify the EVA disk array’s logical volume by this World
Wide LUN Name.

Adjusting volume capacity for copy pair setting
When creating a Flex Copy XP copy pair, the S-VOL’s capacity must be the same as the P VOL. To set a
copy pair’s desired volume, you might need to adjust the volume capacity. This section describes the
procedure to adjust the volume capacity.
Copying data from external disk arrays (using external volumes as P-VOLs)
For A, B, and C in the following description, see Figure 46 .
To adjust the volume capacity to create a pair:
1. Map the external volume (A) as an internal volume (B) of the disk array. Ensure that the volume’s
emulation type is OPEN-V.
