[comp.sys.dec] Sony R/W Optical on DS3100

devin@boulder.Colorado.EDU (Yampalimardilor) (03/14/90)

Does anyone have any clues on how to bring up a Sony Read/Write Optical
on a DECstation 3100?  I added it to scsi_data.c and it is recognized
but I can't really do anything to it - rzdisk, mkfs, and such don't work.
Thanks.

P.S. if you're reading this on comp.unix.ultrix, make sure you mail me or
follow up to comp.sys.dec as I don't read c.u.u.  Thanks.
P.P.S I CAN do a low level (from the boot prom) scsi format on it.

How do you do this?   I don't see anything in my manuals about
formatting SCSI stuff from the boot proms.  I have tried rzdisk on a
SCSI floptical without luck.

Its not documented, but if you do
scsi ?
at the boot prompt, you see lots of interesting options, including
formatting a device.
scsi pb
will Probe the Bus,
scsi rs
will reset the bus.  All of this is quite useful.

>> scsi fm <unit #>
This procedure takes several minutes...
<Grind Grind> ~30-40 mins for our floptical.
