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.
