OK, being at the office and sitting in front of an xterm pointing at my NIM server does wonders for that old brain of mine ...

Here it is: you can get a list of all NIM objects of a certain type. In this case you are interested in the resources of type "mksysb". Do yourself a favour and, when you take the mksysb with NIM means, give it a proper name. In my case this means: hostname plus a suffix. Issue:

Code:
root@nim-server # lsnim -t mksysb | more
aix71_04_02                     resources       mksysb
system_1_mksysb                 resources       mksysb
system_2_mksysb                 resources       mksysb
system_3_mksysb                 resources       mksysb
[...]

If you work your NIM-server like me you perhaps have some installation-images as mksysbs which you use to instll new systems (see above, the aix71_04_02) and the images of the various installed LPARs you take regularly (the others in the list above). Now filter out all the installation images so that only the systems are left and cycle through them, using the -l command line option of lsnim to see the details:

Code:
# lsnim -l system_1_mksysb
system_1_mksysb:
   class         = resources
   type          = mksysb
   creation_date = Sat Oct 15 21:10:56 2016
   source_image  = system_1
   arch          = power
   Rstate        = ready for use
   prev_state    = unavailable for use
   location      = /export/mksysb/sys.mksysb
   version       = 7
   release       = 1
   mod           = 3
   oslevel_r     = 7100-03
   oslevel_s     = 7100-03
   alloc_count   = 0
   server        = master

For instance, a (quick and dirty) code fragment that lists the systems and the creation date of their respective mksysbs, supposing your naming convention is like mine, would be (remove the comments to actually run it):

Code:
lsnim -t mksysb | grep -v '^aix' |\                 # filter out install-images
while read MKSYSB junk ; do                         # read only the mksysb-names
     lpar="${MKSYSB%%_mksysb}"                      # cut off trailing "_mksysb"
     cdate=$(lsnim -l $MKSYSB |\                    # trim o/p to creation date
             sed -n '/creation_date/ s/^.*= //p' \
            )
     print - "$lpar  $cdate"                        # print results
done

I am aware that this is only the sketch of a solution, but it should be fairly straightforward to implement that into a script.

I hope this helps.

appres

APPRES(1)						      General Commands Manual							 APPRES(1)

NAME

       appres - list X application resource database

SYNOPSIS

       appres [class [instance]] [-1] [toolkitoptions]

DESCRIPTION

       The  appres  program  prints the resources seen by an application (or subhierarchy of an application) with the specified class and instance
       names.  It can be used to determine which resources a particular program will load.  For example,

	    % appres  XTerm

       will list the resources that any xterm program will load.  If no application class is specified, the class -AppResTest- is used.

       To match a particular instance name, specify an instance name explicitly after the class name, or use the normal Xt  toolkit  option.   For
       example,

	    % appres  XTerm  myxterm
       or
	    % appres  XTerm  -name  myxterm

       To  list  resources  that  match  a subhierarchy of an application, specify hierarchical class and instance names.  The number of class and
       instance components must be equal, and the instance name should not be specified with a toolkit option.	For example,

	    % appres  Xman.TopLevelShell.Form  xman.topBox.form

       will list the resources of widgets of xman topBox hierarchy.  To list just the resources matching a specific level in  the  hierarchy,  use
       the -1 option.  For example,

	    % appres  XTerm.VT100  xterm.vt100	-1

       will list the resources matching the xterm vt100 widget.
