Re: !!!! My tape drive is not working, it has cost me several days
I'm not sure what is happening here. /tmp is not a great directory to try to back up since the system is changing it all the time. If you're just running some tests, I would try backing up /etc rather than /tmp. When it hangs when you try to extract from the tape does the entire system hang? Are you able to Ctrl-C the command and get back to a prompt? I was a little confused as to whether you were extracting into /tmp or into a different directory. Try extracting into a different directory other than /tmp if you didn't do that before.

Re: !!!! My tape drive is not working, it has cost me several days
Whoa, whoa, whoa. Before you guys get too carried away, how do you know that nothing has been written on the tape? /dev/st0 will automatically rewind after access is completed so everytime you complete writing to the device the tape will rewind to the beginning and it will look like the tape hasn't moved. Try to untar from the tape to a temporary directory and see if there is anything there or simply cat from the tape to a tar file, or do a 'tar tvf /dev/st0' and see if there is a table of contents on the tape. If it's really important that the tape not rewind after writing to it then use device /dev/nst0 instead of /dev/st0. Do a 'man st' for more information about SCSI tape devices. Hope this helps.

Re: !!!! My tape drive is not working, it has cost me several days
Thank you for your advice. mt -f /dev/st0 status and mt -f /dev/st0 rewind both work. how can I make sure that I have permission to write to /dev/st0? how can I check that /dev/st0 are seen from dmesg ?

How about trying to use some of the mt commands, such as mt -f /dev/st0 status or mt -f /dev/st0 rewind These commands are part of the mt-st rpm and should at least tell you if you can talk to the drive. Are you sure that you have permission to write to /dev/st0 and that /dev/st0 are seen from dmesg ? -- R.

!!!! My tape drive is not working, it has cost me several days
I have IBM iseries 230 sever with ridhat linux 7.1on it. I recently boutgh a new tape drive for IBM (20/40GB DDS/4 4mm Internal tape dirve) I think I have setup the tape drive in the server. the server can detect the tape drive now. But when I try to use linux command to back up a small diretory to the tape, it does not work. The tape does not even wind. I used the commamd tar cvzf /dev/st0 /home/jianping I could see the tape-drive activity indicator and Catridge presence indicator on. But When the process finished, I found nothing had been done. the tape did not even wind(it was still in the original status). What counld be the potential problem? Any suggestion will be greatly appreciated!!
