You're lucky -U didn't work, the path you listed would correspond to
partition #5 on SCSI ID #3 (quite possibly your boot drive).
SysV disk ordering is pretty easy:
c = controller (0 is usually onboard SCSI)
t = target (SCSI ID)
d = drive (LUN)
s = slice (partition number)
So your SCSI floppy would be c0t5d0s[0-7] for the different partition
entries.
fdformat is designed for use with S/WD interfaced floppies, such as the
builtin interfaced floppy drives on sun4c systems. The boot PROM sees
SCSI floppies as just another SCSI drive, so to boot off of it you will
probably have to lay down a partition table and write fixed-disk style
boot blocks to it.
This is all from memory which may be in error, the last time I dealt with
SCSI floppies was on a 3/280 running SunOS 4.1.1. Never tried to boot
from one.
