Configuring the Router

2Select Mapping Mode press Enter.

The Mapping Mode screen displays. The current setting is marked with an * next to it.

3Select 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.

4Press Enter to return to the Address Mapping screen.

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.

For additional information about address mapping, see Appendix A, Address and Device Mapping.
