Examples of the Recovery Procedure Path Status
Settings of the LU paths may have been changed by LUN Manager. Check the
settings of the LU paths. If the settings of the LU paths have been changed,
change the settings back to the ones when the volume is mapped. Or use XP
External Storage to perform the Delete LU operation and perform the Add LU
operation again.
The access attribute of the volume may have been changed by HP StorageWorks
XP LUN Security Extension. Check the access attribute of the volume. If the
volume is protected by the access attribute, release the protection.
External device setting
changed
The volume may 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 other copy program. If the volume is set as a
pair volume, the volume may be protected because of the pair status. When
the volume is protected, change the pair status or delete the pair.
The access attribute of the volume may have been changed by XP LUN Security
Extension. Check the access attribute of the volume. If the volume is protected
by the access attribute, release the protection.
Illegal request or
Response error
There is a problem with the connection to the external storage system. The
possible causes are:
•
The fiber cable is not physically connected in the proper way.
• The setting of the topology does not match between the external port and
the target port.
•
If the external storage system is connected through switches, the settings for
the switches may not be appropriate.
Make sure that the fiber cable is connected properly, and then set the Fibre
Channel port properly using LUN Manager.
The LUN security may have been enabled by LUN Manager. Check if the LUN
security is enabled or not. If the LUN security is enabled, disable the LUN
security.

HP StorageWorks EVA Storage System
System Parameters
When connecting an EVA storage system as an external storage system, set the system parameters
of the EVA storage system according to
Table 48 (page 146) . For the system parameters that are
not in Table 48 (page 146) , see the documentation for the EVA storage system and set the parameters
appropriately for the connecting configuration.

Identifying Logical Volumes (Using Characteristic2)
When the connected external storage system is an EVA storage system, LUNs appear as
Characteristic1 in the XP External Storage windows.
If you search for the logical volumes specifying the WWN indicating EVA Port A in the configuration,
as shown in
Figure 44 (page 147) , the logical volumes named LUN 1 and LUN 2 are found for
each of HostGroup-1 and HostGroup-2. In this case, two different logical volumes that have the
same name, such as LUN 1 and LUN 2, are found as the logical volumes that can be connected
from EVA Port A, but you cannot tell which LUN 1 and LUN 2 belong to HostGroup-1 or
HostGroup-2 only by Characteristic1.
