You don't see the second SCSI address because solaris (2.7) has no device
driver for robot devices. One way to solve this problem is either
upgrade to solaris 2.8, which has an so called sgen driver which can
be used to talk to the robot device, or the secondway is to try the
sst driver. You can find this driver in the contrib area of amanda.
There is an short description in the contrib directory how to install it
and some more notes are in docs/TAPE.CHANGERS.
With this dirver installed you can either use mtx or chg-scsi. chg-scsi
is included in amanda, mtx can be found on www.sourceforge.net i think.

mtx is an generic driver with no special things to drive special
features which some library have, chg-scsi is a driver which has
some things builtin which are special for some librarys, handling
of error conditions for example.

That is hardware. barcodes are small labels which you can stick on the
tapes, and an builtin reader can read this labels. Now the software
can create an relationship form the label to the volume name of the tape.
With this you can load very fast a requested volume and the software must not
search through the whole lib.

If your robot supoort this it's a nice feature and you should use it.

No problem, if you give chg-scsi a try you can contact in caase of
problems :-)
