I have an L11000 with 16 drives.

10 of these drives go to a slave server

when i kick off backups the backup can run on 6 drives
but as soon as i try and use a seventh drive (can be any of the 10) it fails 
with a status Code 83

i have logged the bptm and here is what the log looks like

******************************************************

i have checked the tpconfig and sgscan and all the
devices match... 

Any Help would be greatly appreciated

Thanks
