You run strings on the binary to figure out what strings it has built in.
You truss/strace/whatever the binary to see if you can find what flags or
files it's looking for.
You feed the binary something like
--help
or
-h
or
-?
on the command line, to try get it to spit out what it wants.
Basically, all the standard stuff you do with any UNIX program that
is under-documented.
$sudo /etc/LGTOuscsi/sjiinq -?
-?: No such device
Aha, it's looking for a device. Since you know that NetWorker often
uses ``scsidev AT bus.target DOT lun'' for it's scsi device access, you could
do something like:
/etc/LGTOuscsi/sjiinq [email protected]
(use your own bus/target/lun).

Absolutely not.

If it's loaded an online in a drive, use need something like
mt -f /path/to/drive rewind
mt -f /path/to/drive offline
or
mt -f /path/to/drive rewoffl
if your UNIX supports it.
If it's not loaded and online in a drive, you don't need use any other
commands before moving. You just need to understand that you need to
be careful, because if you don't move it back to where NetWorker expects
it to be (or update NetWorker's knowledge of where it is), NetWorker is
going to get confused.

Depends on your jukebox capabilities.
>4. What's the difference between 'movemed' and 'sjimm'? 'movemed'

It's the address you use to talk to the component of the jukebox that
corresponds to the robot(s) / hand(s) / whatever. You get this
information using something like `sjirdtag':
sjirdtag [email protected]
[lots of stuff about slots deleted]
Elem[238]: tag_val=0 pres_val=1 med_pres=0 med_side=0
Tag Data for [email protected], Element Type MEDIA TRANSPORT:
Elem[001]: tag_val=0 pres_val=1 med_pres=0 med_side=0
That last bit is the hand/robot in our 9710.
>Would greatly appreciate any help here?
BTW, I highly recommend the `mtx' program, which is available on
Sourceforge. It works on Linux, Solaris, and others, and is a documented
media-changer utility.
