Description and corrective actionsPath Status
LU paths settings may have been changed by LUN Manager. Either change the settings back
to the values used when the volume was mapped, or perform the Delete LU and then Add LU

If the volume is a pair volume, it may be protected because of the pair status. If this is the case,
change the pair status or delete the pair.

Response error
Cannot detect port
• There is a problem with connection to the external storage system. The possible causes are:
- Make sure the fibre cable is connected correctly.
- The setting of the topology may not match between the external port and the target port.
Make sure that the Fibre Channel ports are set properly using LUN Manager.
- If the external storage system is connected through switches, make sure that the switch
settings are correct.
• LUN security may have been enabled by LUN Manager. If so, disable it.
