I am using SONY SDT 9000 tape drive for backups. Recently, I have started facing one strange problem - Whenever I inserts the tape disk in tape drive, sometimes, it is detected and sometimes I got the error message:
/usr/local/backup/backup.script: line 81: 18611 Broken pipe tar -czf $device usr >>$logfile 2>&1
/dev/st0: Input/output error
mt: The device is offline (not powered on, no tape ?)..
I changed the tape disk but still I am getting this message. It seems I need to replace the tape drive. Since it would be a little expensive affair, so, I want to troubleshoot tape drive first and if I am right, can anyone share info. about the manuals and troubleshooting techniques for this tape drive?
