plug it in, turn it on and do an ioscan.

oops

didn't mean to hit submit...

turn off server
plug in SCSI drive (assuming it's differential so best to turn stuff off).

boot server.

wait while it thinks.

do an ioscan -fnC tape

look for new DLT 8000 drive.

Should be there.

look at device files.

If you don't like the names of the device files, then remake them.

Hi Dave,

Basically you need to install the 'stape' driver into your kernel. Once you have generated a new kernel you should be able to use the drive. After you have rebooted your system you should be able to use the drive.
You can use 'sam' to generate the kernel should you choose.

Hi,
How do i remake the special files?
mksf?
i tried 'mksf -d stape -H
but i get an error (couldnt find driver matching argument)
next...
how do i do that via sam, i also tried creating default drivers via sam but the device is still unknown when i tried using it with TAR

btw, ioscan says device is claimed, device drivers are present except for /dev/rmt/#m files, /dev/rmt/c#t#d#BEST files are the ones present,
Thanks again

Hi Dave,

To create the device files, one of the
easiest ways to do this is:

# cd /dev
# ioscan -fn >/tmp/ioscan.out1
# insf -e
# ioscan -fn >/tmp/ioscan.out2
View the files and compare.

We saw exactly that problem when we attached some DLT 8000's to an HP-PB card on a K-class server. It ioscaned and create device
files OK -- but the DLT's in fact don't work with that type of card, and returned the error you mention.

Moving the DLT's to an HSC-style SCSI card fixed it right up. I think we could tell on the system whether a card (or internal bus externalized) would work by looking at the driver that was associated with the card. scsi3 was no good, but one that used the c720 driver was OK. Note that this was on the adapter card -- I believe the tape driver that it would associate with the discovered tape driver would also be different, but don't still have the info handy. I think stape was good, and there was some other driver (tape2? tape3?) that was wrong. Attaching it correctly automatically assigned the right driver.
