I have a new 5.1.5 test server running on Linux that puts up mount requests for
migrations to a set of 4mm manual drives and the server is never acknowledging 
that
the tape is mounted and therefore never starts the migration.  I noticed that 
when
I was doing manual labeling that the first few requests were not being serviced 
but
they magically started acknowledging the tape in the drive and the labeling 
process
continued as normal.

I've checked the device class, path, drive and all of the other relavent things 
and
they all look clean.  Proof of this to me is that the labels were put on the 
tapes
just fine.  Now, when I test migration the drives never acknowledge the tapes.

I'm thinking that there is some switch or setting that I need to toggle to make
this work.

Any ideas?
