HP-UX 11.00, Omniback 3.10, autochanger problems -schgr

[Jeff Patrick]

I recently installed Omniback A.03.10 on one of my servers, and upon adding my robotic library (A4853A) and 2 DLT 7000 tape drives within OB, I cannot successfully scan tapes using the robotics. I got errors such as 'can not unload auto exchanger medium (medium not present)'

I loaded patch PHSS_21643, which sounded like it would fix the problem, but it didn't. I loaded patch PHSS_22167, and since then I can't even get into the 'devices' screen, I just get a red bug with the word 'Error'. Using uma from the command line, I can successfully move the tapes from the drives to the slots & vice versa, provided I take the tape drive offline prior to unloading the drive. I'm using driver 'schgr'. Any ideas? Do I need to load 'spt0' into the kernel (it's not currently). Previous successful server instances I have use /dev/picker and spt, while this one uses /dev/rac/c3t6d0 & schgr. But they also have different types of autochangers. Thanks in advance for any help.

The document ID of the instructions is
KBAN00000190.

This will provide you a document that contains the info in the previous reply.

Hi Rick,

I currently have a problem with my D-class and a DDS3 autoloader. Your posts so far have helped me a great deal.

You continue to refer to documentation "KBAN00000190"

Thankfully this document is included with the post I am currently replying to. I was wondering how I would normally access this documentation directly (getting to this particular post involved doing a google search on KBAN00000190).

Reading through this documentation I have still hit a brick wall though.
I am running on a D-class with ext_bus being a c720.
I am currently running with all required drivers (sctl, schgr etc).
The picker still doesn't appear in an ioscan.

Hi,

A tumb rule for drivers:
Which driver to use for the picker:
ext_bus= c700; C720 use sctl
Otherwise spt.

If tape drive is stape, then picker should be sctl.
If tape drive is tape2, use spt.

Glenn, did you try the following command:
insf -e.

Jeff have you tried the following:
mc -p /dev/picker -s S1 -d D1 # Move tape from slot1 to device 1

Good luck

I pressed the submit button by excident.

The schgr driver is just for diagnostics and ioscan, it's not for controling the picker.

Do you have the driver specified in the kernel e.g:
driver 8/5.7.0 sctl

Testing OBII with the autochanger, use uma:
/opt/omni/lbin/uma -ioctl /dev/picker
move S1 D1
move D1 S1

Have Fun

Jeff,
The following error will accur if you assign the wrong device file to INDEX (medium not present)'
If you can move tape from slot to slot or slot to drive robatic is working.

Thanks to all for your help on this issue...in my case, I found the resolution in the 'SCSI Reserve/Release (drive)' setting under the tape drive's advanced properties in the Omniback software. Once this field was marked, my autochanger worked properly without the addition of any drivers or patches. (from the command line with uma it had already been working properly, just not in Omniback) Thanks again to all who responded.
