Well, I just answered my own question. I removed the 3480 definations on
my sandbox LPAR. I then tried to reference a tape dataset which was
catalogued on a 3480. I got a JCL error:

IEF210I TSH009A2 STEP020 SYSUT1 - UNIT FIELD SPECIFIES INCORRECT DEVICE
NAME

<JCL>
//STEP020  EXEC  PGM=IEBGENER,
//             REGION=4096K
//SYSPRINT DD  SYSOUT=*
//SYSUDUMP DD  SYSOUT=*
//SYSIN    DD  DUMMY
//SYSUT1   DD  DISP=SHR,DSN=TSH009.BADTAPE
//SYSUT2   DD  SYSOUT=*
//
</JCL>
