Hi all!
My SCSI DAT tape make some problems. It cannot "seek". Its
a Sony SDT-10000. - I detected the problems with "dds2tar"...
Here an example
[root@panorama /root]# mt seek 10000
/dev/tape: Input/output error
[root@panorama /root]# mt status
SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 512 bytes. Density code 0x13 (DDS (61000 bpi)).
Soft error count since last status=0
General status bits on (5010000):
WR_PROT ONLINE IM_REP_EN
[root@panorama /root]# mt rewind
Now again it is like newly inserted...
[root@panorama /root]# mt status
SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 512 bytes. Density code 0x13 (DDS (61000 bpi)).
Soft error count since last status=0
General status bits on (45010000):
BOT WR_PROT ONLINE IM_REP_EN
[root@panorama /root]# mt tell
At block 0.
[root@panorama /root]# mt fsr 10000
[root@panorama /root]# mt tell
At block 10000.
[root@panorama /root]# mt bsr 5000
[root@panorama /root]# mt seek 10000
/dev/tape: Input/output error
[root@panorama /root]# mt bsr 2000
[root@panorama /root]# mt tell
At block 3000.
[root@panorama /root]# mt status
SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 512 bytes. Density code 0x13 (DDS (61000 bpi)).
Soft error count since last status=0

I think that the bios from the tape is not capable to execute the
seek properly - fsr and bsr (and everything else) work fine.
The Drive is fairly new and the bios-revision is very young...
What do you think!?
[root@panorama init.d]# cat /proc/scsi/scsi
Attached devices:
... ... ...
Host: scsi0 Channel: 00 Id: 10 Lun: 00
Vendor: SONY Model: SDT-10000 Rev: 0101 <-----
Type: Sequential-Access ANSI SCSI revision: 02
Or is this a problem related to the controller?
[root@panorama init.d]# cat /proc/scsi/sym53c8xx/0
General information:
Chip sym53c875, device id 0xf, revision id 0x3
IO port address 0xb000, IRQ number 11
Using memory mapped IO at virtual address 0xc8823000
Synchronous period factor 12, max commands per lun 32
Many, many thanks for any help!
Bye,
Rob
