I am not having luck making a /dev/sd1a partition on a jaz
disk.  The FAQ for zip and jaz from the freebsd site does make
a jaz disk via the auto feature of disklabel.  An older FAQ on
making Jaz disks does work under 2.1.6 but not 2.2.1/2.2.2.

I'm looking for pointers here....below is some data from my 
previous attempts.
 
(I'm not actively reading the lists...can you e-mail replies and
I'll summerize back to list)

If you go to the Iomega site and look up the solaris-jaz connectivity
Iomega recommends a configuration like this....
