CBR3601I Entry of volume volser into library library-name1 rejected. Duplicate in library library-name2.
Explanation
Volume volser could not be successfully entered into library library-name1. There is already a volume record in the tape configuration database for this volume indicating that it is in library library-name2.
System action
The volume is scheduled for ejection.
System programmer response
Determine if the volume is in library library-name2 (an audit of this volume may be necessary or try entering the cartridge into library-name2). If it is, duplicate volsers are not allowed. If it is not, the volume record pertaining to this volume can be updated using IDCAMS to indicate library-name1 or deleted entirely so that the cartridge can be entered into this library.
