Our Storagetek L80 tape library (yes, the infamous one that you're tired
of hearing about) does not support the moving of media via the LED
panel. Our ATL tape libraries do. We would like to be able to move tapes
in and out of drives outside the purview of NetWorker. I know this will
require having to use some of the utilities under /etc/LGTOuscsi like:

movemed
sjimm
ldunld

but I'm not sure if we would all of these and or the differences between
sjimm and ldunld. I thought I heard somewhere that the mt command was
also required at some point, e.g. to first unload the tape before using
the movemd, but can't remember.

Can someone provide me with an example of how to move a tape from slot
30 into drive 1 (/dev/nst0) so as to have the tape available for use
with tar utility and an example of how to unload the tape and move it
back after tar completes?

Here's the info from the inquire output:

/dev/sg0
[email protected]:SEAGATE ULTRIUM06242-XXX1522|Tape, /dev/nst0
[email protected]:SEAGATE ULTRIUM06242-XXX1522|Tape, /dev/nst1
[email protected]:SEAGATE ULTRIUM06242-XXX1522|Tape, /dev/nst2
[email protected]:SEAGATE ULTRIUM06242-XXX1522|Tape, /dev/nst3

Would appreciate this.

Thank you

george
