Re: Ultrium 3-SCSI Issue on Centos 5
You can't hang that tape drive on a raid controller. The connection is right, but the card can't talk properly to the drive.
The drive needs a dedicated scsi controller.
I ran into the same problem on an rx6600 running HP-UX.
The drive showed up but did not work right.

Re: Ultrium 3-SCSI Issue on Centos 5
In fact this problem happens to me on time. If I try another tape, I can read and write with "tar" on it without problems.
If the problem you enter on the other link, I would not work with any tape.
I've been searching google, but problems with this type of Ultrium, are solved by adding the following lines to / etc / rc.d / rc.local:
for x in / proc / driver / cciss / cciss [0-9] *
do
echo "engage scsi"> $ x
done
This makes sense?. They do not understand these lines.

Re: Ultrium 3-SCSI Issue on Centos 5
The behavior on Centos is different than HP-UX.
The raid card may be the exact same card if your box is built by HP.
These Ultrium tape drives DO work much better on a dedicated scsi connection. Give it a try, the card is not outrageously expensive.

"
for x in /proc/driver/cciss/cciss[0-9]*
do
echo "engage scsi" > $x
done
"
in /etc/rc.d/rc.local ?
