Thanks to all who responded to my query. It turns out the problem was
"overthinking" on my part. What I had tried to do was the following:
- Jaz drive is sd3
- "newfs sd3c"
this appeared to work just fine
- "df /dev/sd3c"
this produced the error "not a UNIX filesystem", so I assumed I had
done something wrong.
The documentation from Iomega ("Using Iomega Drives on a Sun Workstation",
available from their fax-back line but apparently not available online)
simply states to run the newfs command and then to mount the file system.
I assumed that this would not work if the "df" command would not work
but I finally decided to just try it and lo and behold it works! Further
experimentation reveals that "df /dev/sd3c" works after you issue the
"mount" command but not before, and "df /dev/rsd3c" worked at all times.
Anyway, the final conclusion is that the drive works fine. Get the
"format.dat" file from the sun-managers archive, extract the entry for
the Jaz 1GB drive, label the disk cartridge using format, run the newfs
command, and then mount it. Voila, instant 1 gigabyte removable file
system. The only trick is figuring out how to allow users to do this
without compromising system security.
