This, unfortantly, takes me back to Andries Brouwer's listing of changes
to the internal SCSI structures. As you can see below, devfs does not
extend the number of partitions supported:
Partition check:
/dev/scsi/host0/bus3/target0/lun0: p1 p2 p3 p4 < p5 p6 >
/dev/scsi/host0/bus3/target0/lun1: p1 p2 p3 p4 < p5 p6 p7 p8 p9 p10 p11
p12 p13 p14 p15 >
When mounting /dev/scsi/host0/bus3/target0/lun1/disc via rawfs, I'm still
left with only 15 partitions which are visable.
I agree with Goswin Brederlow, that devfs provides the right foundations
for doing this. Also, the devfs FAQ [1] does bring up that 6 bits should
be set aside for SCSI partitions. However, it does not seem to be
actually implimented. Rather, the present 2.2.16 devfs patch appears to
just provide an alternative naming method to the same structures.
So, is there anyone already working on large devfs SCSI addressing
structures similar to the ones stated in the devfs FAQ?
Thanks.
