Desale,

Are you sure there isn't a tape stuck in a drive or in the picker?  The
last entry from the log shows "Changer failure".

Our 3583 experienced numerous failures, mostly due to the picker not
grabbing the tape properly and leaving it stuck in the drive.  At that
point everything is out of sync - the library, TSM, etc.  You should take
the library offline, open the door, and look inside.  Ensure that what TSM
thinks is happening in the library matches its physical state.

There is an engineering change that adds some small springs to the LTO
drives to improve tape ejection.  Also, the latest firmware for the
library tells the picker to extend farther when grabbing a tape to help
prevent "drops".

The 3583 does not have a window through which to examine the inner
workings of the library, so you have to take it offline and open the door
to see what's happened.  Because of that we've removed the screws that
hold the top panel on the library.  Now, if we have to look inside it, we
just remove that panel and peek in.  This is not recommended if you live
in an area prone to earthquakes.  We don't.
