Description Edward Grabczewski 2001-08-10 13:57:21 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)

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. 

How reproducible:

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. 

Additional info:

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 ?

Comment 2 Edward Grabczewski 2001-08-13 12:10:57 UTC
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.

Comment 3 Doug Ledford 2001-08-23 21:28:28 UTC
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
the bug tracker at: http://bugzilla.fedora.us/
