Hi,
check the messages of the Linux system (/var/log/messages, but I am not sure) 
if you find some hints about access to the device, or about some hardware 
topics.
Did you install the latest version of 7.5 ? I know that there were some topics 
about cloning. Better to read the release supplements in EMC powerlink.
Check if the tape and the save sets are marked as suspect. If yes, try to 
relable the tape, properly the cartridge is defect, or the the device.

Regards
