I'm not sure which of these gave me re-probability, but...
ls /dev/*scsi*
crw------- 1 root wheel 18, 0 Nov 4 23:55 scsisuper
In my kernel config file:
# These are only for watching for bitrot in old SCSI code.
# also need to execute: ``(umask 077; mknod /dev/scsisuper c 18 0)''
pseudo-device su #scsi user
pseudo-device ssc #super scsi
Then run (assuming you didn't swap out your boot drive):
/sbin/scsi -f /dev/rsd0.ctl -r
And to test, do an inquiry of the device just added (say sd2):
/sbin/scsi -f /dev/rsd2.ctl -c "12 0 0 0 v 0" 0x40 -i 64 "s8 z8 z16 z4"
