I have this nailed down a little bit more.  I ran the following:
IBMtapeutil -f /dev/IBMtape1 inquiry 80
and
IBMtapeutil -f /dev/IBMtape2 inquiry 80
Then I rebooted this Linux on i5 lpar (hosted underneath an i5/os lpar). I
ran the IBMtapeutil commands again and the serial numbers flipflopped
between the two.  Of course, TSM doesn't like it when path names change. I
am thinking the possible solutions are either to get Linux to stop
flipflopping the serial numbers or to tell TSM not to give a rip about the
serial numbers.  Trouble is, I can't figure out either way.

[ADSM-L] TSM loses tape drives (again and again and again...)






Seems pretty consistent that when we IPL our Linux partition on our
iSeries TSM will no longer talk to the tape drives.

I do NOT see the serial number.  Am I looking in the wrong spot?
