External CD-rom shared between 2 machines - bjames - 08-18-2018

This may be a dumb question, but can you connect 2 computers to a single external SCSI CD-ROM drive?

It would look like this:

Octane. —> CD-rom. ——> o2

I can do this with emu keyboard samplers have 2 on either side of the CD-ROM as the keyboards have built in termination. The only caveat is you can’t try to save from both machines at once. Emu allows you have have 2 masters on a SCSI chain.

I'm not aware of any way to share a SCSI device between two systems, but I used to hot-swap harddrives and CDROM drives a few years ago (probably not a good idea and not recommended).

Internal SCSI controller was bus 0, external SCSI controller was bus 1
I would have a HDD on my external SCSI bus, use it, etc etc. Then when I wanted to hotswap a CDROM drive on it I would unmount the external HDD, unplug the HDD, plug in the CDROM drive and as root:

Code:
scsiha -r 1
scsiha -p 1
ioconfig -f /hw

where the "1" is the scsibus to reset (-r) and probe (-p)

That's what I used to do to hotswap SCSI devices on a running Indigo2 and o2. I don't bother doing that today, I don't want anything blowing up
