CA VM:Tape for z/VM

Issue/Introduction

I have a z/VM Version 6 Release 4.0, service level 1901 system running CA VM:Tape (TM) Version 02.0 RSU-1901.
 
The following statement is issued via my userid (FOSTER) authorized for VM:Tape:
 
VMTAPE MOUNT SCRATCH 181 DSN FOSTER.T0956 EXPDT 06/05/20 ( LABEL SL 
 
The following response is received:
 
VMTMNT0005I MOUNT '0181' request accepted.                         
Foster at TKEVM; T=0.01/0.01 08:57:18                             
Tape 0181 attached                                                 
08:57:18 VMTMNT0073I Volume 'OX0286' ready on 0181 (C292) R/W SL.  
08:57:18 VMTMNT1112I Ending command MOUNT with completion code 0.  
 
After writing to the tape successfully, a VMTAPE LIST is issued against the volser:
 
vmtape list OX0286                                                              
VOL=OX0286 OWNER=FOSTER  EXPDT=2020/158  LABEL=SL  CUNIT=C292       36/ENHXF    PWD=NONE
           LASTUSER=FOSTER  LDATE=2020/155 LUNIT=C292 COUNT=104                
           FILESEQ=0001 CRTDT=2020/155 CTIME=08:57 DSNAME=FOSTER.T0956.EXPDT.06/05/20
           TMUSER=Y0000000000000000 TMUSED=Y TMUSEDH=E8                         
           TMBYTES=0000000000000000        
 
Notice the DSNAME= information; the DSN information via MOUNT SCRATCH (FOSTER.T0956) has been concatenated with the EXPDT information (06/05/20).
 
Is this normal behavior or a bug?

Cause

Using incorrect format of MOUNT command.

Environment

Release : 2.0

Component : CA VM:Tape for zVM

Resolution

EXPDT is an option and needs to be in parenthesis and the date format is
yyyy/ddd
,


Specify this instead:

VMTAPE MOUNT SCRATCH 181 DSN FOSTER.T0956 (EXPDT 2020/157 LABEL SL


and verify with a VMTAPE LIST after.
