All has been working OK until now.
I have backups of my Sun servers on tapes #1 to #4.
I took these out, labelled new ones #11 to #14.
cart_ctl -l is OK - the changer locations are good.
Now when I back up, at the end of tape #11 I
get "illegal <storage-element-number>
argument 'Segmentation Fault - core dumped" - I think
the mtx command is being passed the tape number, not
the slot number.
