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

The LUN security may have been set by LUN Manager. Check if the LUN security
is set or not. If the LUN security is set, remove the setting of the LUN security.

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
Universal Volume Manager to perform the Delete LU operation and perform
the Add LU operation again.
The volume may have been set as a pair volume for data copy. Check if the
volume is set as a pair volume of ShadowImage, TrueCopy, 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.
