Barcode script for tape lib

Craig A. Sharp — Mon, 16 Apr 2001 16:09:03 GMT

I am using a Surestore E 2x20 DLT8000 tape library.
The lib is able to read barcodes. I am looking for a script to read the barcode data and print it out to a file.
My plan is to have the data automatically sent to Informix. I can do the informix end but I have no clue on how to extract the barcode data from the library.

Thanks,

If you have OmniBack II check out the uma utility (man uma).
The script would be very similar to this:
ROBOT=/dev/robot/c2t3d0 # robotics device
echo "stat" > /tmp/controlfile
/opt/omni/lbin/uma -ioctl $ROBOT -barcode < /tmp/controlfile > /tmp/list

The output file /tmp/list should have the barcode as the fourth field of each output line.
I think that the uma utility is available from HP w/o purchasing OB2 (at least the man page hints at this.) If you can't get the uma utility you will probably have to write a c program to do a scsi inquiry.

You might also check out the 'mc' command though you would then have to install the autochanger driver and devices.
man 1m mc

execute the command "omnimm -repository_barcode_scan . This will do a barcode scan and produce a report of all tapes in the exchanger.

Hi all,

Thank you for your replies. We do not use Omniback. We had some serious problems that prevented us from using that solution.

I will checkout the MC command and see if that will do what I need.

Please let me know if there are any other ideas not usind Omniback.

Thanks

Craig

Ok Craig. I tried the mc command and here's what happened.
ROBOT=/dev/robot/c2t3d0 # SCSI pass-thru robotics device (set to your picker device)

mc -p $ROBOT -r S > /tmp/list.txt
The output looked like this
ST_slot_1 FULL 000107
ST_slot_2 EMPTY
ST_slot_3 FULL 000187

.
The 3rd field is the barcode. It appears that MC will dothe job.
