hi

we installed amanda on our debian sarge server to backup it's data on a
sony lib-81 ait2-tape-library.

as changer script, we use the well documented chg-zd-mtx script.

all configurations are stored in /etc/amanda/neurochirurgie, where we
also put the chg-zd-mtx script with it's chg-zd-mtx.conf configuration
data.

so far everything worked well, but now, as we would like to update the
barcode database (like descripted in chg-zd-mtx), we receive the
following output:

neurochirurgie:/home# amtape neurochirurgie update
amtape: scanning all 7 slots in tape-changer rack:
slot 1: reading label: Input/output error
slot 2: reading label: Input/output error
slot 3: reading label: Input/output error
slot 4: reading label: Input/output error
slot 5: reading label: Input/output error
slot 6: reading label: Input/output error
slot 7: reading label: Input/output error

the update takes very long time, as if the barcode-reader in the
tape-library would make reading errors.

funnily enough, the reader doesn't seem to have problems with reading
the tags:

neurochirurgie:/home# mtx -f /dev/sg2 status
 Storage Changer /dev/sg2:1 Drives, 8 Slots ( 0 Import/Export )
Data Transfer Element 0:Empty
     Storage Element 1:Full :VolumeTag=A05RSH
     Storage Element 2:Full :VolumeTag=A05RSJ
     Storage Element 3:Full :VolumeTag=A05RSK
     Storage Element 4:Full :VolumeTag=A05RSL
     Storage Element 5:Full :VolumeTag=A05RSM
     Storage Element 6:Full :VolumeTag=A05RSN
     Storage Element 7:Full :VolumeTag=A05RSP
     Storage Element 8:Full :VolumeTag=A05RU8

we didn't label the tapes with amlabel. we just put the stickers which
came with the library on the tapes. could this be the error?

thanks a lot for your help.

cheers, christian
