Unable to move, backup, or write labels to LTO-6 tape

#1

Hello, Arkeia is producing various, vague errors whenever I try to do anything with my LTO-6 tapes. I have already set my tape drives to LTO6 drives but the errors persist.

When I try to label an LTO-6 tape, it tells me:
“Cannot load tape from slot # to drive #”

It gives me the same error when I try to move the tape to the drive. It’s maddening! Whenever I move LTO5 tapes, they are fine. Anyone know what to do?
