We do this:

*
* CMS 23 disks at 1st Level
*
 MDISK 2390 3390 2184 107 VMRESB RR ALL      CMS23A   190
 MDISK B390 3390 0282 107 VMRESB RR ALL      CMS23B   190
 MDISK 2393 3390 1664 200 VMRESA RR ALL      CMS23    193
 MDISK 239D 3390 1864 300 VMRESA RR ALL      CMS23    19D
 MDISK 239E 3390 1007 250 VMRESA RR ALL      CMS23    19E
 MDISK B39E 3390 3139 200 VMRESB RR ALL      CMS23B   19E

Of course we use the CMS IPLER.

Subject: Re: How comments treated by DIRMAINT


These block comments don't solve the problems of deleted minidisks. (I
reverted to that too when we started with DIRMAINT).  Nor do they help
when working like me with two alternating runtime minidisks.  Eg MAINT
190 and 490 have two different CMS levels.  When switching levels
(forward or backout), I swap the addresses in the directory.  I don't
use DDR, address swapping can often be done in flight: old users go one,
new users get the new stuff, impossible with DDR (for CSM I have
different saved segments). With comments on the MDISK card itself, it
also always clear which is which, even if a phone call interrupts your
thoughts in the XEDIT session used to swap the addresses (did or didn't
I swap this one already? In the day preceeding this trick, I often
encountered this in real life and QQUIT was often the only safe way to
go on). Standard example:
  MDISK 0490 3390 2362 107 VTERES RR ALL WMAINT MMAINT
  MDISK 0493 3390 1433 167 VTERES RR ALL  WMAINT MMAINT
  MDISK 019D 3390 681 146 VTEBKP RR ALL  WMAINT MMAINT
  MDISK 049E 3390 2687 190 VTERES RR ALL  WMAINT MMAINT
  MDISK 0190 3390 399 107 VTE52R MR ALL  WMAINT MMAINT
  MDISK 0193 3390 0001 167 VTE521 MR ALL  WMAINT MMAINT
  MDISK 019E 3390 1735 190 VTE521 MR ALL WMAINT MMAINT
When looking at this, you don't know which is the newest copy (the
volsers are different in this case, and might help here, but this is
from my test system, on other systems these CMS minidisks might be all
located on the same volser, a matter of chance/malchance).
