You need to remap the tape drives with device tree. This problem might
occur if you reboot the server while one tape drive had issues, so the
mapping messed up on OS. It happened a couple of time in our environment.

Check that the /dev/rmt/* entries match the devices in the robot. You can
see if they do by inserting a tape into the drive and then issuing a mt -f
/dev/rmt/* status for the /dev/rmt/ number you have the drive configured to.
It should show a device is present, if not then you have a configuration
issue.
