The problems are tha the sg? links doesn't correspond to the real
devices shown by /proc/scsi/scsi (Which matches the real situation)
sg0 matches the first disk, OK
sg1 matches the Medium changer, OK
sg2 matches nothing...... There is no target 2 on host1 !!!
sg3 matches the DLT tape drive
sg4 matches the DAT tape drive
The other problem is the st? links.
st0 is linked out into nothing ...
Seems like 3 host adapters is too much for devfs......
Do I need an upgrade ?
