scsi Sony dds3 tape problem

jdudeck · #1 24th March 2004, 05:56 PM

I have a Sony SDT-9000 drive on an SIIG scsi card with Fedora Core 1. When I put a tape in, and (as root) want to access it, for example with the command:

mt -f /dev/st0 status

I get :

/dev/st0: No such device or address

Now, if I give the command:

mt -f /dev/osst0 status

it thinks and clicks the drive for a moment and gives:

/dev/osst0: No such device

Now, if I give the first commmand again, it gives me the correct response from mt.

I get a similar sequence of results if I try to access the drive with dump or restore.

After this happens, then I can access the drive normally until the next reboot.

What gives?

Does

Code:

dmesg

show the card as being recognised before you run that command?

Yes, it is recognised. But after running the command 'mt -f /dev/osst0 status', it then adds some more lines to the dmesg output.

Before running the mt command:

After running the mt command, the following are added to the end of the output:

What kernel do you have?

Code:

uname -a

jdudeck · #5 24th March 2004, 08:27 PM

Linux prague.sim.org 2.4.22-1.2115.nptl #1 Wed Oct 29 15:42:51 EST 2003 i686
i686 i386 GNU/Linux

By the way, I have started an up2date running on this machine. The Fedora Core 1 I just installed is from a fairly early set of FC1 CD's that I bought from CheapBytes.com.

Yeah, give that a try. It should update your kernel too.

I finally managed to get up2date to complete on the machine. It appears to have resolved the problem with /dev/st0, which now behaves properly. Thanks for your help.

P.S. I had a terrible time with up2date -- the package downloads were very slow and had lots of errors. When I tried it on Monday morning it ran 5 times faster and finished without a hitch.

P.S. I have another problem, but I'll start a new thread.

Good to know.
