I have an LTO-3 as described in the subject. I've installed lin_tape and lin_taped RPMs for RHEL 5 but still it doesn't work.

/var/log/lin_tape.trace has:

/dev/IBMtape opened. lin_taped Tue Dec 16 15:53:18 2008 Failed to detect any tape drives. lin_taped Tue Dec 16 15:53:18 2008 Failed to detect any changer devices. IBMtapeDevDriver Tue Dec 16 15:53:18 2008 lin_tape_add_class_device() entry lin_tape_add_class_device() entry lin_tape_add_class_device() entry lin_tape_add_class_device() entry

How can I solve it?

Thanks in advance
