Connecting EVA arrays

Identifying logical volumes of EVA arrays (using Characteristic 2)

When the connected external array is an EVA 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
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
External Storage XP's panes. The first 32 characters of Characteristic2 indicate the World Wide LUN
Name found on the EVA array. You can identify the EVA array's logical volume by this World Wide
LUN Name.

Alternate path's behavior when an EVA array is connected

When an EVA array is connected, the alternate path's behavior differs depending on the EVA array's
microprogram version.
The alternate path's behavior differs between EVA arrays of the microprogram version shown below
and EVA arrays of earlier microprogram versions:
• Array type: EVA3000/5000
Examples of Recovery
Procedure
LUN Manager might have enabled
LUN security.
Check if the LUN security is
enabled or not. If LUN security is
enabled, disable LUN security.
69, logical volumes named LUN 1 and LUN 2 are found for both HostGroup-1 and
69, you can identify logical volumes by referring to Characteristic2 in
