Somewhere (I have since tried to find the source, but have failed) I have a CPCONFIG EXEC that automates much of the maintenance of CF1 and CF3. It includes maintaining previous generations of SYSTEM CONFIG:
cpconfig DMSVML2060I MAINT CF1 linked MR as 0CF1 file mode I The following "*SYSTEM CONFIG" files exist on the I(CF1) disk now: FILENAME FILETYPE FM FORMAT LRECL RECS BLOCKS DATE TIME -1SYSTEM CONFIG I1 F 80 271 6 2010-02-16 07:58:27 -2SYSTEM CONFIG I1 F 80 271 6 2010-01-12 09:04:29 -3SYSTEM CONFIG I1 F 80 270 6 2009-11-06 17:37:29 -4SYSTEM CONFIG I1 F 80 270 6 2009-11-06 17:37:29 -5SYSTEM CONFIG I1 F 80 261 6 2009-10-28 13:52:38 -6SYSTEM CONFIG I1 F 80 246 5 2009-09-11 10:18:11 -7SYSTEM CONFIG I1 F 80 246 5 2009-08-25 07:37:17 -8SYSTEM CONFIG I1 F 80 240 5 2009-08-24 09:39:30 -9SYSTEM CONFIG I1 F 80 239 5 2009-07-30 07:37:17 SYSTEM CONFIG I1 F 80 271 6 2010-03-03 13:00:37 Do you want an automatic copy/rename of them as a backup before starting?

Understanding how SERVICE and PUT2PROD silently update the CF1 and CF2 disks is important. I prefer to think of CF2 as a resource to be used only if CF1 gets trashed (my human, hardware, or any other error). : : _____________________________________________________ This message contains information which is privileged and confidential and is solely for the use of the intended recipient.
