Missing Tape Autochanger

[Keely Jackson]

Hi

I have a quantum DLT4500 with autochanger attached to a 11.0 machine but when I do an ioscan the autochanger is showing as uknown and unclaimed. I have added the spt driver (the same one as used by another autochanger on another machine) in to the kernel and rebooted but the autochanger os still not recognised. How do I get it to be claimed and known?

Many thanks

Keely

Hi,

Is autox0 and other exchanger related kernel drivers in an "IN" state? You can use sam to check.

Check also that you have this patch (for HP-UX 11.00) or a superceding one:

PHKL_15955 1.0 autox0 cumulative patch.

Hope this helps. Regards.

Hi again

Thanks. I added the autoX driver (patch is installed) into the kernel and I can now see the autochanger and the device file /dev/rac/c2t5d1 has been created. Is this ok as on the other machine the device driver is the spt driver and the associated device file is /dev/scsi/cxtxdx?

I added the autochanger and dlt into omniback ok but I am unable to get it to access the drive, I tried scanning a tape and it failed.

Any sugesstions gratefully received?

Hi,

Can you try this to see if the picker works:

# /opt/omni/lbin/uma -ioctl /dev/c2t5d1
/dev/rac/c2t5d1> stat

Regarding configuration and whether you need spt or sctl, this document will help:

If the tape drive driver is stape, then the picker driver is sctl.
If the tape drive driver is tape2, then the picker driver is spt.

Hope this helps. Regards.

Hi Keely,

Enable the "schgr" driver in the kernel. REbuild the kernel and reboot the system. If you do a ioscan after this, you should see the autochanger as claimed and the device files named as /dev/rac/cxtydz for the autochanger.

Hope this helps.
