Hello,
I run an Adaptec 2940 UW controller under Linux 2.0.35 and the Adaptec AIC7xxx
driver version: 5.0.19/3.2.4. The SCSI tape stuff is compiled as a module.
I have several UW disks attached and a SCSI DLT tape drive which is also an UW
device.
The tapedrive can write 35 GB to a tape at a speed of more than 200 MB/sec.
When I write to the tape I get the following messages
Feb 7 23:51:11 hostname kernel: Detected scsi tape st0 at scsi0, channel 0, id
13, lun 0
Feb 7 23:54:42 hostname kernel: (scsi0:0:13:0) Data overrun detected in
Data-Out phase, tag 29;
Feb 7 23:54:42 hostname kernel: Have seen Data Phase. Length=65536, NumSGs=1.
Feb 7 23:54:42 hostname kernel: sg[0] - Addr 0x400000 : Length 65536
Feb 7 23:54:42 hostname kernel: st0: Error 27070000.
and tar responds to this with:
Prepare volume #2 for /dev/nrmt0 and hit return:
After I hit return (without changing the tape) it continues properly.
What is this error message about ?
On another box where I have almost the same configuration but the tape connected
to a seperate controller I dont get this message and I can write non-stop to the
tape.
Any suggestions are welcome. :-)
Harry
