Examples of Recovery Procedure

Path Status

There is a problem with connection to the external array.
The following are possible causes:

Cannot detect port

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 appropriate.

Check if the fibre cable is connected properly, and then
set the Fibre Channel port properly using XP LUN
Configuration and Security Manager Software.

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 (page 157)

, 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 (page 157)

, 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 Name found on the EVA array. You can identify the EVA array's logical
volume by this World Wide LUN Name.
