How to add an Iomega 1GB SCSI Jaz drive to a Sparc workstation

This works on a Sun Sparc Ultra 1 running Solaris 2.5.1.  Your mileage
may vary.

1. Shut down the workstation.

2. Connect the Jaz drive to the SCSI port.  The cable that comes with the
   Jaz drive works nicely.  Select a SCSI address.  I chose four, based
   on the output of dmesg(1M), as an unused SCSI address.  Insert a blank 
   Jaz cartridge in the drive.

   NOTE NOTE NOTE!!!!  You can NOT use the Tools Cartridge that comes with
   the drive.  This is because Jaz uses software write-protection, and
   the Tools Cartridge is write-protected to the nth degree.  So, run out
   and buy yourself a blank cartridge or two.  I bought ONE today at CDW
   for $135.00 with tax.  Ugh.

3. Boot the workstation and rebuild the devices (boot -r).

4. Check for the presence of the Jaz drive:
   # dmesg | grep -i jaz
   You should see the Jaz drive.  Also, be sure your other SCSI devices
   are all properly functional.  Bad Things[tm] will happen if you have
   a duplicate SCSI address on the chain (e.g. the CDROM drive and the
   Jaz drive have the same SCSI ID).

5. Edit /etc/format.dat and enter the following info for a Jaz drive.
   This info is used by format(1M).
   disk_type="Jaz 1GB"\
   	:ctlr=SCSI\
   	:ncyl=1018:acyl=2:pcyl=1020:nhead=64\
   	:nsect=32:rpm=3600:bpt=16384
   partition="Jaz 1GB"\
   	:disk="Jaz 1GB":ctlr=SCSI\
   	:2=0,2084864

6. Format your Jaz cartridge via format(1M).  Be sure to select the right
   drive!  Don't want to smoke your good drives, right?  I put the entire
   filesystem on slice 2.

7. Create a filesystem on your newly formatted Jaz cartridge.  Use:
   # newfs -v /dev/rdsk/c0t<your SCSI addr>d0s2.

8. Mount your new Jaz cartridge on a mount point of your choice.  I used
   /jaz.  REMEMBER:  Create the mountpoint via mkdir(1) BEFORE you attempt
   to mount the new Jaz filesystem.
   # mount /dev/dsk/c0t<your SCSI addr>d0s2 /jaz

Enjoy!
