UNKNOWN DEVICE in IOSCAN

[Leandro Lucena.]

Hi Everyone,

Can someone please tell me what driver I need to install to satisfy
the unknown device listed below? I have a K460 (HP-UX 11.11) with an HP DLT surestore
4/40 Tape Library. Also, are there any
DLT Library patches that I should be aware of?

Thanks,
Leandro Lucena.

Well, the ioscan output shows that your library is connected to a HP-PB based SCSI interface. I'm sorry, but I doubt that you will get that working... the tape2 driver is not supported with DLT8000 drives (and does not work either).

On your K-Class you need to connect the drive to an HSC-based interface... then stape is responsible.

Best regards...
Dietmar.

Deitmar,

This Library was working fine on this same server, but on a 10.20 system. The issue is how to assing the schgr driver to this controler. That is the way it was working after. Do you know how to do this?

Thanks a lot for all!!

Note: The cable I'm using to connect it is a HVDS SCSI.

Thanks a lot for all!!

Is your schgr driver loaded in the kernel? If not load it through SAM. I don't think this driver is loaded by default in 11 & 11i.

[generic_1]

You need to load the driver into the kernel SAM is a very easy tool to do this with.

You must have the sctl and schgr drivers in the kernel.

See this posting. There is an attachment(s) that provide all of the information on setting up the robotics/kernel etc.

Sorry... but after reading the previous posts I feel there's some need for clarification. In the HP9000 world there are two families of drivers:

SIO: scsi3, disc3, tape2, spt, autox0, ...
WSIO: c720, sdisk, stape, sctl, schgr, ...

Since your bus is claimed by scsi3, you are in the SIO world. This is legacy stuff and no longer maintained... it's even removed from newer OS releases. Forget *all* about sctl and schgr... these are WSIO drivers which have *nothing* to do with your bus and your library. :-)

If you still plan to use the library on this bus then you need to think about the spt driver. Configure it into the kernel and add a line like this to /stand/system.

driver 10/4/12.0.0 spt

Rebuild the kernel an reboot. The you should see "spt" claiming the device.

Check now what major number spt uses:

# lsdev -d spt

Create a device file... in your case:

# mknod /dev/rscsi/c2t0d0 c 0x020000

You should now be able to use this device file with tools like mc(1) or Data protector.

# mc -p /dev/rscsi/c2t0d0 -q

But concerning the DLT... the latest DLT supported by tape2 is DLT7000. DLT8000 may work with tools like tar of cpio using a generic density... (not with fbackup or Data Protector, BTW). Have you ever tested if your DLT is really working at DLT8000 speed and density? One reason for not supporting HP-PB interfaces is the slow speed...

Best regards...
Dietmar.
