HP Ultrium Tape Drive 960, errors out when backing up linux compressed files or big files

Hi,

We've been unsuccessful in our backups so far
everytime we backup linux compressed files (.tgz) or folders containing big files.

The following error message comes out:

mptscsi: ioc0: attempting task abort! (sc=c23ae640)
scsi0 : destination target 3, lun 0
command = Write (6) 00 00 28 00 00
mptscsi: ioc0: task abort: SUCCESS (sc:c23ae640)
st0: Error with sense data: Current st0: sense key unit Attention
Additional sense: Scsi bus reset occurred
tar: /dev/st0: Cannot write: Input/output error
tar: Error is not recoverable: exiting now

We're using RedHat Linux AS 4.0 on a HP Proliant ML110 G4 server.

The bios can detect the tape drive and we
have installed the latest driver from HP website for the Ultrium 960.

If the folder to be backedup is relatively small, backup is successful..however, if
the files in the folder are quite large or
if there are several folders to be backed up
we encounter the error mentioned above.

We have cleaned the tape drive, inserted new tapes and so far still no success.

Hope anyone can help us solve this problem.

Thanks in advance,

Olegna

Hi,

By the way we used this command to backup:

tar -cvf /dev/st0 bkup.tgz
