I have problems reading from my IDE-Streamer (Seagate STT20000A).
The device is recognized as /dev/st0. dmesg shows:
Attached scsi tape st0 at scsi0, channel 0, id 0, lun 0
st0: try direct i/o: yes (alignment 512 B), max page reachable by HBA
The device is primary slave (hdb), ide-tape is unloaded and ide-scsi is
loaded via /etc/init.d/boot.local (OSS 10.0, Kernel 2.6.13-15). Grub is
provided hdb=ide-scsi. Writing on the tape with tar apparently works
without problems as the streamer issues typical sounds and the
procedure lasts reasonably long. But when displaying, verifying or
restoring a backup the device starts doing something for some seconds
but in fact, nothing happened.
/proc/ide/hdb/settings says that UDMA is active and that the device
works in PIO write-only mode.
I upgraded from SuSE 9.3 where everything worked fine. Under 9.3 I had
to turn DMA off for a proper function, putting hdparm -d0 /dev/hdb.
Now, /dev/hdb no longer exists.
Can anyone help me?
