/* generic SCSI header file. We use the same minor number format
|
|
* as on SGI except that the flag bits aren't available because they
|
|
* are used as the board index.
|
|
*
|
|
* The minor number format is:
|
|
* FF UUU III (FFUU UIII)
|
|
*
|
|
* Where:
|
|
* FF is the board index
|
|
* UUU are the LUN
|
|
* III is the SCSI ID (controller)
