We have an absolutely huge number of DASD (many thousand) and on 2 CU's of 
2048 devices each we can have a mix of 3390-03, 3390-09 and 3390-27 (STK 
Equiv. - 32760 cyls).

We know by address where each size is but  the labelling conventions have 
other meanings so we cant easily tell the size from the volser (unless we 
specify each one).

Each volume will have an extent defined to userid SYSPACKS that will be 
the true size of the DASD (specific extent - not 0-END). 

In our DIRMAINT EXTENT CONTROL file we have the following under defaults 
:-

:DEFAULTS. 
  3390                 3339 DECLARE ALL 3390'S AS MODEL 3. 
  3390-01              1113 
  3390-02              2226 
  3390-03              3339 
  3390-04              4959 
  3390-09             10017 
  3390-27             32760 

However, when the VCONTROL files are created we get the following (this is 
an example of a Mod 27 volume with the ACPMAINT entry defines as 1-END) ;-

DEVTYPE= 3390 
MAXBLK= 3338 
ARCH= CKD 
ENTRY= 1 3338 ACPMAINT 2090 * 
EXCLD= 0 32759 SYSPACKS D7D8 * 

Is there any easy way to get the 1-END entries to recognise the size of 
the DASD based on the largest extent defined? Because SYSPACKS is in the 
EXCLUDE LIST this is mainly so that DIRMAP could recognise overlaps 
correctly.
