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
