Getting a 970C_42CD allocation error when executing a CA Endevor processor. What is wrong?

C1A0010E  ALLOCATION ERROR RC=970C-42CD, DDNAME=C1INIT01.        
C1A0011E  IKJ56894I DATA SET USERID.COBRCGY.LINKCTL NOT ALLOCATED+.
C1A0012E  IKJ56894I STORAGE MANAGEMENT SUBSYSTEM DETECTED AN ERROR

970C is a Severe SMS VTOC service error.
42CD is a duplicate data set name exists in the catalog. 

Check the data set identified in the C1A0011E error message and determine if it is already allocated. 

Review the processor and if the processor is allocating and cataloging a file like this:

//INIT1    EXEC PGM=BC1PDSIN,MAXRC=0                        
//C1INIT01 DD  DSN=&LINKCTL,DISP=(NEW,CATLG),              
//             UNIT=&WRKUNIT,SPACE=(TRK,(2,2),RLSE),        
//             DCB=(RECFM=FB,LRECL=80,BLKSIZE=3200,DSORG=PS) 

Add a step to the processor to first delete the file before allocating it.
