Stunning. That's the answer. On z/OS 1.13 (and z/OS 1.12 by your note), SYSLIB does not qualify as anyname, while on z/OS 1.11 it does. Ironically, ANYNAME qualifies as anyname on either level.

While you would think SYSLIB would qualify as anyname apparently it dose
not.

12.4.1.3 anyname DD Statement


A DD statement must be included for each permanently mounted or mountable
volume referred to in the job step. These DD statements are used to
allocate devices: they are not true data definition statements.
Concatenated DD statements are not allowed.

Because IEHLIST modifies the internal control blocks created by device
allocation DD statements, these DD statements must not include the DSNAME
parameter. (All data sets are defined explicitly or implicitly by utility
control statements.)

The DD statement can be entered:


       //anyname DD UNIT=xxxx,VOLUME=SER=xxxxxx,DISP=OLD



The UNIT and VOLUME=SER parameters define the device type and volume
serial number without requiring that a real data set be allocated on the
volume.

Subject:        IEHLIST LISTVTOC inconsistency
Sent by:        IBM Mainframe Discussion List<IBM-MAIN@bama.ua.edu>



I just ran into a situation where IEHLIST is providing different results
for the same volume depending upon whether it is run from a z/OS 1.11
system or a z/OS 1.13 system.

The JCL looks like this:

//jobname JOB etc.
//*
//LIST    EXEC PGM=IEHLIST
//SYSPRINT DD  SYSOUT=*
//SYSLIB   DD  UNIT=3390,VOL=SER=DSKAA9,DISP=SHR
//SYSIN    DD  *
    LISTVTOC VOL=3390=DSKAA9
/*

Under z/OS 1.11, IEHLIST lists the VTOC as expected. Under z/OS 1.13,
IEHLIST issues the following message and quits:

IEH106I UNAVAILABLE DEVICE TYPE OR VOLUME I.D. SPECIFIED

The JCL is identical and the job is being run against the same volume in
both cases. The volume is available to both systems. I haven't been able
to find any relevant hits. Has anyone else seen the same symptom?
