The serial number of the library in the database did not match the serial number of the library found using the device special file specified. UPDATE PATH cannot be used to change libraries, and thus, the new device must have the same serial number as stored in the database unless the serial number in the database is empty.
The command is not processed.
Reissue the command, and specify a valid DEVICE parameter value. If this is a new or different library with a different serial number, a new library and path should be defined with DEFINE LIBRARY and DEFINE PATH.
