SCSI TAPE

[smg_atlas]

Hi

Is there anyone who can help me with the error message I receive in the HP9000 syslog:

Jan 15 12:52:27 assrvsapb1 vmunix: SCSI TAPE: dev = 0xcd0d5040 I/O error during
close
Jan 15 13:51:22 assrvsapb1 vmunix: SCSI TAPE: dev = 0xcd0d5040 I/O error during
close

You are having a problem with /dev/rmt/c0t13d0xxxx (or the short version of the device node name with the same minor device number). I/O error (EIO) indicates that some form of hardware error occurred but that is all the host computer can know. It could be a bad tape; the drive might require cleaning; or the drive itself may be failing. Are there any indicators on the drive itself?

No I dont see red light on the tape drive.
I could not rewind the tape earlier:
#/usr/bin/mt -f /dev/rmt/7mn rew
/dev/rmt/7mn: No such device or address
Some how I lost my device /dev/rmt/7mn and had to run
#insf -e
and
#insf -eH 0/0/4/1/0.5.0
and the result was:
crw-rw-rw- 2 bin bin 205 0x0d5040 Jan 15 12:51 7mn
crw-rw-rw- 2 bin bin 205 0x0d5040 Jan 15 12:51 c13t5d0BESTn
After that I have tried to use cleaning tape few times and was able to tar /home filesystem and rewind the tape.
But I can see the messages :

SCSI TAPE: dev = 0xcd0d5040 I/O error during close

Pls help me to rectify the problem.......

If you were able to use then cleaning tape a few times and then were able to write that is a definite indication of a hardware/media problem. My first cut at this would be another tape. Is there some reason that you are using a norewind device node? That normally is used when you want to put down multiple images on the same tape but it is fraught with danger as it is extremely easy to misposition the tape and overwrite a backup.

I/O errors on a tape drive usually indicates a bad drive.
You may consider to test the drive with LTT or a tool of your choice and finally get the drive replaced if needed.

Thanks very much for your support guys.
I managed to use cleaning tape and insert new data tape and it all works.
