Above error occurring in second step of job AXFFB01 which allows to fallback to previous release.
Environment:
z/os 2.2, CA Datacom/AD 15.0 falling back to 12.0
Cause:
PREVIOUS OPEN ERROR REQUIRES CLOSE   BEFORE NEW OPEN ATTEMPT       
                                           
After some of the open error conditions,   it is required that a close occur to ensure full cleanup of conditions.                
Resolution:
Adding the highlited CLOSE statement (job AXFFB01)  below resolved the case:

//SYSIN DD * 

COMM OPTION=CLOSE,DBID=601 
LINK DBID=601 
ACCESS STATUS=WRITE,DBID=601
