Connecting EVA disk arrays

Identifying logical volumes of EVA disk arrays (using Characteristic 2)

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
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
Examples of recovery procedures
The volume may have been set as a pair volume for data copy.
Check if the volume is set as a pair volume for Business Copy XP,
Continuous Access XP, or another copy program. If the volume is set as a
pair volume, the volume might be protected because of the pair status. If
the volume is protected, change the pair status or delete the pair.

Check if the volume is set as a pair volume for Business Copy XP,

the volume is protected, change the pair status or delete the pair.
There is a problem with connection to the external disk array. The following
are possible causes:
• The fibre cable is not connected properly.
• The topology setting between the external and target ports does not
match.
• If the external disk array is connected through switches, the switches'
settings might not be appropriate.
Check if the fibre cable is connected properly, and use LUN Manager to
set the fibre channel port properly.
Hitachi SANtinel may have set LUN security.
Check if LUN security is enabled. If LUN security is enabled, disable LUN
security.
49, logical volumes named LUN 1 and LUN 2 are found for both HostGroup-1 and
Figure 49, you can identify logical volumes by referring to Characteristic2 in
