Media Manager status code: 167

Message: ADAMM GUID is not unique in the database

Explanation: A volume entry that was added to or changed in the EMM database had a specified ADAMM GUID. It was a duplicate of the ADAMM GUID for another volume already in the EMM database. All volumes in the EMM database must have an ADAMM GUID that is either unique or null. (ADAMM is Advanced Device and Media Management, and a GUID is a Global Unique Identifier.)

Examine command output (if available) and the daemon and reqlib debug logs for a more detailed message on the error.
From the daemon debug log file, determine the volume that has an ADAMM GUID conflict with the volume entry that is added or changed.
