Description of problem:
Following an upgrade to RH 7.1 Professional, the Tandberg DLT 8000 tape
drive fails to work. This seems to be down to the /dev/st0 device, which
does not appear to be configured correctly. During the installation the
DLT device was switched off. Following installaton I powered it up so that
KUDZU would recognise the device but no screen appeared. The DLT is
attached to an Adaptec 29160 SCSI controller on an ASUS CUV4X-D
motherboard (which does not use an Intel 440GX chipset as far as I can
tell from the manual.
This setup works on RH 7.0 and 6.2 for that matter.
Steps to Reproduce:
1.Install RH 7.1
2.Login and open a terminal window
3. dump -0a -b 10 -f /dev/st0 /usr
Actual Results: DUMP: <usual information>
DUMP: write error 20 blocks into volume 1: Invalid argument
DUMP: Do you want to rewrite this volume? (C?es or no)
Expected Results: The drive would have dumped /usr to tape.
This works with RH 7.0 and 6.2. Seems to be a 7.1 bug.
Neither cpio or tar are happy either - which points to the device.
I have tried different tapes but similar problems occur.
Doug: is this the "odd length" issue ?
I have attached the DLT tape drive to my RAID SCSI controller and the TAR
command works, so it seems to be a driver problem for the 29160.
I don't actually have any confirmed "odd length" issues that I can point at. As
far as this is concerned, I would need to see the Identify information for the
tape device (from a dmesg output) and then I might have a clue what's going on.
I suspect that the card and tape are having problems in negotiation due to the
fact that the card is a 160 capable card.
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
