Adding tape drive

I have a HP tape drive (C2984A) that I want to add to my C360 running 11.0. I'm trying to use SAM to add this drive. Which of the following device drives do I need to add to the kernel for this drive to work?
cs80, disc1, hpib1, schgr,scsi1, spt, spt0, stape, tape1, tape2, target

Thanks,
Ron

Re: Adding tape drive

Just do a insf -e
it will automatically install the drivers for the attached tape drive.

Then do a
ioscan -fnC tape
to check whether it is CLAIMED.

Re: Adding tape drive

Ron,

I could certainly be wrong, but I though insf only installed device files, not drivers. Not being exactly sure what the C2984A is, I would say that one of the following should do it: stape, tape1, tape2. Try configuring those into your kernel and see which one your drive uses (in ioscan). You can always take the others back out of the kernel later.

Re: Adding tape drive

I agree with Pete. You can add them all to the kernel(it won't hurt) and then afterwards do an ioscan -fnkC tape and so which one is used and always remove the others not used later of just leave them in.

Re: Adding tape drive

Do a lsdev -C tape
to see what tape drivers
are already in your kernel.

After physically installing the device, do an insf -e
to install the device files.

Determine if the device is
claimed or not.
ioscan -fun -C tape.

You may need to add a driver
to the kernel or you may
be all set.

Re: Adding tape drive

It's a dds3.

add stape to kernel and reboot, then insf -e and then ioscan -fn

Re: Adding tape drive

tried the insf -e, then the ioscan. Tape drive didn't show up. The SCSI ID on the tape drive is set to 0. I would think that this ID is already taken. How do I see what SCSI ID are currently assigned on my machine?

Re: Adding tape drive

Ron,

You can tell the SCSI id from ioscan:

ioscan -kCtape
H/W Path Class Description
=================================================
0/0/1/0.0.0...... tape...... HP...... C1537A
0/4/0/0.6.0...... tape...... QUANTUM...... DLT8000


In this instance, the SCSI id's are 0 and 6.

Re: Adding tape drive


If you expect a SCSI conflict, then IMMEDIATELY take that tape drive off, or potentially suffer some SERIOUS data loss.

A SCSI ID is only pertinent to the BUS it is on (like a scsi card).

ioscan -fn >/tmp/ioscan_`hostname`.txt

then more /tmp/ioscan_`hostname`.txt

find the card the tape drive is on and look at the ID's on that PATH.

Re: Adding tape drive

hi,

I've got the same problem when I install the tape driver c1537A (DDS3 tape),I tried the ioscan, insf as well as adding the device and rebuild the kernel. However it does not show the tape.
I have disconnected the tape drive during the OS installation. Should I connect and power on the tape drive during installing OS ?I remember that it configures the tape drive and device files automatically.
What should I do ?

Re: Adding tape drive

There are 2 driver families... SIO and WSIO. SIO is only used by "older" server systems. The last one was the K-Class which actually is a SIO/WSIO switter.

All workstations and "more modern" servers use the WSIO familiy drivers. For supported tape drives this is the stape driver only (plus lower layered ones like c720/c8xx, td, etc).

The INSTALL kernel during cold installation contains all those drivers. Depending on the discovered hardware the final kernel is customized... so the stape is likely to be excluded, but may be added later without problems.

If we are talking about a K-Classe with an HP-PB interface then tape2 would be needed, probably along with scsi1/scsi3/target.

Best regards...
