Ahh, I bet that's what's going on here.  Thanks for the info..

We have two edl's and the problem is happening on both of them.  I'll
come in one morning and about 1/4 of the drives will be in service mode,
and some of the tapes will show up as "unlabeled". 

This morning I came in and all of my vcb proxy server drives were in
service mode..

Also, in my first post I meant to put that I have CDI off and not CDL..
:)

Yes that was definitely one issue we were experiencing.  Try having
EMC come and upgrade your EDL's software....  Nice free easy to
implement fix.

Its so annoying to recreate physical problems in the virtual world for
the sake of completeness.
