Examples of Recovery ProcedurePath Status
The volume might have been set as a pair volume for data copy.
Check if the volume is set as a pair volume of XP Business Copy, XP Continuous Access, XP
Continuous Access Journal, or some other 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.
Response
error
XP LUN Security Extension might have changed the volume's access attribute.
Check the volume's access attribute. If the volume is protected by the access attribute, release
the protection.
There is a problem with connection to the external array. The following are possible causes:
• The fibre cable is not physically connected properly.
• The topology setting does not match between the external and target ports.
• If the external array is connected through switches, the switches' settings might not be ap-
propriate.
Check if the fibre cable is connected properly, and then set the Fibre Channel port properly
using XP LUN Configuration and Security Manager Software.
Cannot de-
tect port
XP LUN Configuration and Security Manager Software might have enabled LUN security.
Check if the LUN security is enabled or not. If LUN security is enabled, disable LUN security.
Connecting EVA arrays
System parameter settings for connecting EVA arrays
When you connect an EVA array as an external array, set the system parameters of the EVA array
according to the following table. For the system parameters that are not in the following table, see
the manuals of the EVA array and set the parameters appropriately for the connecting configuration.

Identifying logical volumes of EVA arrays (using Characteristic 2)
When the connected external array is an EVA array, LUNs are displayed as Characteristic in XP
External Storage's panes.
If you search for logical volumes by specifying the WWN that indicates EVA Port A in the configuration,
such as in Figure 69, 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 69, you can identify logical volumes by referring to Characteristic2 in
XP External Storage's panes. The first 32 characters of Characteristic2 indicate the World Wide LUN
