Path Status Examples of Recovery Procedure

External device

setting changed

Settings of the LU paths may have been changed by LUN Management. 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

Universal Volume Manager to perform the Delete LU operation and perform the

Add LU operation again.

The access attribute of the volume may have been changed by LUN Security XP

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

The volume may have been set as a pair volume for data copy. Check if the

volume is set as a pair volume of Business Copy XP, Continuous Access XP,

Continuous Access XP - Journal, or some 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 LUN Security XP

Extension.

Check the access attribute of the volume. If the volume is protected by the

access attribute, release the protection.

Cannot detect port There is a problem with connection to the external storage system. The possible

causes are:

 The fibre 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 fibre cable is connected properly, and then set the fibre

channel port properly using LUN Management.

The LUN security may have been enabled by LUN Management. Check if the

LUN security is enabled or not. If the LUN security is enabled, disable the LUN

security.
