Address and Device Mapping

SCSI devices attached to the router are discovered during power on. The router defaults to AUTO mapping mode, which automatically maps the SCSI devices at each power on. The router maps devices sequentially as it scans the channels and discovers the devices (devices are discovered by channel, lowest SCSI ID and LUN first). Devices are mapped to FC LUNs, starting from LUN 0 to LUN 63 (64 LUNs are supported, including an optional router LUN).

You can select the FIXED mapping mode to lock the current device mapping so that it doesn’t change during subsequent power cycles, even if devices are added, moved, or removed. FIXED is recommended for environments where device configuration may change and a fixed mapping from the application to the target devices is required. Devices added after selecting FIXED will be automatically mapped to an available FC LUN. See Changing the Mapping Mode (AUTO or FIXED) on page 3-24.

Figure A-1 on page A-2is an example of how the router will map SCSI devices (SCSI channel:target:LUN) to FC LUNs.
