Does anyone know what I need to do to correctly adress such a drive?

I have the modules "usb_storage" and "st" loaded but I don't get any
/dev/(n)stX ...

Kernel 2.6.31-gentoo-r10 ... hmm

Do I have to add my own udev-rules ??

Thanks for any pointers, Stefan

Forgot to mention: it is connected via USB ... internally ...

I see it via

but you do get /dev/sgX devices?
You have multiple lun support compiled in?

Yes.

Looks like the four SATA-disks, one cdrom and the tapedrive (recognized
as CDROM?):

# ls -l /dev/sg?
crw-rw---- 1 root disk 21, 0 3. Mär 2010 /dev/sg0

Yes, I do.

After a reboot, with a tape inserted, I get:

# ls -l /dev/sg?
crw-rw---- 1 root disk 21, 0 3. Mär 2010 /dev/sg0
crw-rw---- 1 root disk 21, 1 3. Mär 2010 /dev/sg1
crw-rw---- 1 root disk 21, 2 3. Mär 2010 /dev/sg2
crw-rw---- 1 root disk 21, 3 3. Mär 2010 /dev/sg3
crw-rw---- 1 root cdrom 21, 4 3. Mär 2010 /dev/sg4
crw-rw---- 1 root tape 21, 5 3. Mär 2010 /dev/sg5

and also

# ls -l /dev/st0*
crw-rw---- 1 root tape 9, 0 3. Mär 2010 /dev/st0
crw-rw---- 1 root tape 9, 96 3. Mär 2010 /dev/st0a
crw-rw---- 1 root tape 9, 32 3. Mär 2010 /dev/st0l
crw-rw---- 1 root tape 9, 64 3. Mär 2010 /dev/st0m

# ls -l /dev/nst0*
crw-rw---- 1 root tape 9, 128 3. Mär 2010 /dev/nst0
crw-rw---- 1 root tape 9, 224 3. Mär 2010 /dev/nst0a
crw-rw---- 1 root tape 9, 160 3. Mär 2010 /dev/nst0l
crw-rw---- 1 root tape 9, 192 3. Mär 2010 /dev/nst0m

I am able to write and read a tape, yes.

But dmesg still looks ugly!

Not very trustworthy?
