Topic: Error with sense data on Seagate STT20000A

[Todd Pearsall]

I've read a bunch of messages on this error, but can't seem to find a definative solution (or one that works for me at least).

Here's what I see at boot up:
Jan 21 18:35:24 house2 kernel:     ide1: BM-DMA at 0x1488-0x148f, BIOS settings: hdc:DMA, hdd:DMA

When running a backup I get:
Jul  1 03:00:01 house2 kernel: st0: Error with sense data: [valid=0] Info fld=0x0, Current st09:00: sense key Illegal Request
Jul  1 03:00:01 house2 kernel: Additional sense indicates Invalid command operation code
...

I tried setting the backup device to ide:
# /sbin/e-smith/db configuration setprop backup Device /dev/nht0
# /sbin/e-smith/signal-event conf-backup
# /sbin/e-smith/backup
Backup aborted: No tape loaded


Any recommendations?

Thanks,
Todd

AFAIK, /dev/nht0 is the _IDE_ tape device.
You try using /dev/nst0
(the _SCSI_ tapedevice)
ALso, ide-scsi module must be loaded

Thanks for the respone.

That's what I understood, but when I use that is says no tape loaded.  Go figure.

ide-scsi is loaded, but looks like it is not in use:

Is there any configuration I should be playing with?

For the archives...

Strangely enough, after the upgrade to 5.5 /dev/nst0 is no longer the tape device, but /dev/nht0 is.  So far it looks like the "Error with sense data" problem has gone away, but I'm still testing.
