Hi,
Thanks for the response. The Tape Drive Reset error message is gone now. I did pull the Tape Drive out of the socket and pushed it back in after 10 seconds while the system was up. I successfully did a backup. Can you believe it, it hadn't backup in 2 years? Though I've only been here 1.5 years, no one showed me how to do it until recently. Realized it is such an easy thing to do.
Thanks Ken and thanks to the Octel Technician who guided me over the phone.
