Thanks for all replies. Our SPACE command also uses DCE to determine model
number. Two points:
1. The reason I'd like to display a 'meaningful' model number is not for
ordinary allocation but for volume-to-volume activities like copy
(ADRDSSU) or mirroring. In such cases, it's important that the target
volume match the source volume. Of course total capacity is the key, but
an eyeball indicator would be helpful. We've had cases where a mismatched
'Mod-9' was incorrectly selected as target for a full-volume operation.
For such purposes, all Mod-9s are not equal.
2. I tried DS P on one of our 'Mod27' volumes. It's reported as a Mod-9
rather than Mod-A:
UNIT DTYPE M CNT VOLSER CHPID=PATH STATUS
RTYPE SSID CFW TC DFW PIN DC-STATE CCA DDC CYL CU-TYPE
0149E,33909 ,A,000,R13DLB,A0=+ BF=+ C3=+ AE=+ A5=+ B7=+ C0=+ C4=+
2107 1400 Y YY. YY. N SIMPLEX 9E 9E 30051 2107
************************ SYMBOL DEFINITIONS ************************
This volume has a capacity of 3,0050 cylinders. But it's not EAV.
3. The SPACE command is very handy for day to day operations. As a TSO
command, it can be issued at READY or anywhere a command line is
available. No special authorization or environment is required.

As Dale McCart points out, a "Mod6" volume (smaller than Mod9) is also
shown as
Mod9 by the DS,P command:

Cheryl Watson looked this up for me in the SHARE requirements system. The
SHARE
requirement number is SSMVSS12002. It contains the following. Don't shoot
the
messenger. :\
