Path Status
Examples of Recovery Procedure
External device setting
changed
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 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 Data Retention
Utility.
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, Continuous
Access, Continuous Access 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 Data Retention
Utility.
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
following are possible causes:
•
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.
Check if the fibre 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.
