The disk driver numbering situation is not as bizarre as it looks. Look at sd(4) and GENERIC. The scheme is there. Internal disks are sd2 and sd6. Why? sd 0/1 is the standard numbering in plain old sun shoeboxes, and they want you to be able to plug them in trivially. The 8 and 18 are the "slave" numbers, composed by (SCSI-ID*8)+SCSI-LUN. Now, if some of these Wren's and MaxStors would only come with LUN switches as well as ID switches, one could make a real disk farm.
