Hi. I wish to use the su device, which is configured into my kernel via the 'pseudo-device' line. MAKEDEV doesn't handle creating entries for this. I can't find any documentation anywhere as to the correct value for the minor device number. The man page states: The su driver provides support for a process to address arbitrary locations on the scsi bus. Minor numbers are mapped 1:1 to bus:target:lun. The lowest three bits being LUN and the next three bits being TARGET. Re- maining bits are the bus number. So, this leads me to think that the following should work (for bus 0, target 2, lun 0): mknod /dev/su0-2-0 c 18 16 But any attempt to get a response via scsi(8) returns the "Device not configured" message (the same command works fine if I link the su0-2-0 file to the rdevN.ctl file and run the command again). Any suggestions/comments? TIA, AS To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
