Hello all,
I had StorageTek come in and replace the robotic MPCL card in the L700
library but that didn't fix the problem. It turned out to be a bad
communications/signalling cable on the drive chassis that houses the
tape drives. It's the cable that the library uses to communicate with
the drives. They ganked the old one out and put in a new one and all my
drives came back up "empty" :)
Cheers,
- Mike
