All,

We new to Amanda and are having an issue getting the bar code reader to work in our tape changer. We have an HP C7200 (2 LTO drives/20 media slots) connected to an N class HP Server (HP/UX 11i amanda-2.4.4).

The HP supplied utils (ltt tools) are able to read the barcode info from the tape silo, move the tapes, and inventory the robot with no known issues.

I have tried to configure the chg-scsi interface with marginal success. If I turn off the barcode reader (havebarcode 0) then I can get Amanda to run backups and amtape seems to act normal. If I understand correctly, this also means the system must do a linear search for the media in the silo, instead of using the barcode info.

Once I turn on the bar code reader (havebarcode 1) then I error messages from amtape and backups fail. When I try using the chg-scsi (chg-scsi -slot 3) command directly to move the media from slot n into the drive, it moves the media, but then reports an error:

BarCode == 1 and enubarcode == 1

with and exit status of 2

If I issue the same command again it returns success.

The other oddity I have noticed is if I issue the command to inventory the silo (chg-scsi -inventory) the label file grows very quickly to fill the disk.

Thank you in advance,
George Henson
