Gill,
I suspect that the ce had the drive in service mode, either to swap the drive
for another one, or to run diag tests. The ce would have to take it out of
service mode. This can be done from the front panel of the library.
Or some cable is not plugged into the drive unit. Of course I would assume if
this is the case, there are library errors generated for this.

I've looking at the TS3500 Tape Library web console and for some reason
that drive says it is offline. I recycled the drive from there but that
hasn't changed anything.
I don't see a selection to put this online through the TS3500 library
manager or from the front panel. Is this something that is supposed to
happen automatically when the drive is powered up or through some other
process? I don't see how there is some function from an AIX standpoint
that needs to be done but, again, having never seen this either not
sure.
