Select the option you want and press Enter:
AUTO—lets the router assign the FC LUN to each device anytime you power up the
router.
FIXED—tells the router to keep the same FC LUN as currently assigned for each
device. This reserves the same FC LUN for each device, even when you power down
and power up the router. The router retains the FC LUN, even if the device is no
longer connected.
The system confirms that the changes are made.

Changing Device Addresses (FC LUNs)
You can change the FC LUN for any device connected to the router. You can only change
the FC LUNs when the address mapping mode is set to FIXED. As long as you stay in
FIXED mode, all FC LUNs you change will be retained even if the device or router is
powered off and back on or if the device is removed and reconnected.
You can set the FC LUN for devices to any number between 00 and 63 by selecting the FC
LUN that you want the device to map to. You cannot select the same FC LUN as the
router’s LUN.
When in FIXED mode, the router will discover any new devices or existing devices that
were removed and reconnected to a different location. These newly discovered devices
will be in AUTO mode and will be assigned an FC LUN by the router. You can change
these FC LUNs by following the steps below.
If you assign an FC LUN that is already in use, the FC LUNs for the two devices are
swapped. For example, if device A has LUN 01 and device B has LUN 03, and you assign
03 to device A, the LUN for device B becomes 01.
