There is a commerical version of a changer software that I use for Solaris
platform from HIARC.  They have a product called jukebox driver.  That will
work on almost any changer.  It worked well for me because chg-scsi doesn't
work for me.  I'm using Dell Powervault 120 changer (from ADIC vendor)
running on a Solaris Intel box.  But the downside to using the commerical
driver is that it costs us $479.  You can download it and test it with one
week demo license key.  That is what I did.  If you plan on using it, let
me know and I'll send you a changer script for use with amanda to interact
with HIARC jb driver.  

HIARC have a website at http://www.hiarc.com.  According to their website,
the following known jukebox devices that the driver works on:

* ADIC
* ATL
* Breece Hill Technologies
* Exabyte
* IBM
* M4 Data
* Overland Data
* Plasmon
* QualStar
* Spectra Logics
* Storage Tek
* StraightLine
* Sun
* Tandberg Data

And the following optical jukeboxes:

* DISC
* Fujitsu
* HP
* IBM
* Maxoptix
* Plasmon
* Sony

Like what Gary said, if you already got the jukebox, test it out with
chg-scsi and if it does not work then try stctl, which is another free
product that the U of MN use for their amanda backup on a Sun Jukebox (I
can't remember the model number but its from Sun) on a Sun Enterprise
E450.  stctl can be found at http://www.cs.pdx.edu/~eric/stctl/.  So if
neither works, then try mtx or chio.  If not, then you can use hiarc's jb
driver as a last resort like I did for my Dell Powervault 120.  Since it's
a commerical product, it is more likely that it will be supported.

Good luck,
Josh
