Barcode Reporting Mismatch Errors Unexpectedbehaviorcanoccurifthe
library’sbarcodereportingconfigurationdoesnotmatchthetypeof
barcodelabelsthatarebeingusedandwhatthestoragemanagement
softwareexpects.Themostcommonproblemsthatoccurare:
 Thelibraryisconfiguredtoexpectachecksumcharacterinbarcodes,
butthebarcodelabelsdonothaveachecksumcharacter.Inthiscase,
thebarcodereportedbythelibraryis“missing”theright‐most
character.Thisisbecausethelibrarytreatsthelastcharacterinthe
barcodeasachecksumcharacter,whichitdoesnotreport,whenthe
characterisactuallypartofthebarcode.
 Thelibraryisconfiguredtousebarcodelabelsthatdonotincludea
checksum,butthebarcodelabelsincludeachecksumcharacter.Inthis
case,thelibrarytreatsthechecksumcharacteraspartofthebarcode
andthereforereportsaseeminglyrandom“garbage”characterasthe
lastcharacterofthebarcode.
 Thelibraryisconfiguredtousebarcodesthatincludeachecksumand
performchecksumverification,butthebarcodelabelsdonothavea
checksumcharacter.Inthiscase,thelibraryreportsaverificationerror
oneverybarcodelabelbecausethecharacteritisusingtoperformthe
checksumverificationisnotachecksumcharacter.

Important
After the utility completes, the LCM reboots. After the library completes its
initialization, it rescans the barcode labels of all media in the library. This rescan
takes up to 45 minutes per frame to complete.
