Subject: [IBM-MAIN] QUESTION ON VATLIST

Hallo To All,
 
My question is about the VATLIST.  I am not sure if I am using the proper 
terminology.  This member is found in SYS1.PARMLIB and is scanned by the system 
to verify the disk status after an IPL is performed.  What I would like to know 
what the fields represent.  I have fair idea but I would like a confirmation.  
I GOOGLED for VATLIST but the search gave me results that I am not looking 
for.  Here is an example to better explain my question VATDEF IPLUSE(PRIVATE) 
SYSUSE(PRIVATE)
AGIA* ,0,2,3390    ,N
CTUI* ,0,2,3390    ,N
DBI0* ,0,2,3390    ,N
TMCI* ,0,2,3390    ,Y
WORK1*,0,0,*      ,N

The first field is the VOLSER, I  think that the "2" represents that the volume 
is mounted as PRIVATE.  The "0" (in the second field) means that the volume is 
mounted as STORAGE.  I am not sure what the "0" in the first field indicates 
and what the "N" or "Y" in the last field signifies.

I welcome all your input.  Also, for the future could someone tell me where I 
can find this information..
 
Thanks in advance for your help.
