Trying to IPL 2d Level but getting the following:
17:22:10 HCPISU951I CP VOLID 54XPG2 NOT MOUNTED
17:22:10 Start ((Warm|Force|COLD|CLEAN) (DRain) (DIsable) (NODIRect)
17:22:10 (NOAUTOlog)) or (SHUTDOWN)
17:23:32 START COLD DRAIN NOAUTO
17:23:32 Start ((Warm|Force|COLD|CLEAN) (DRain) (DIsable) (NODIRect)
17:23:32 (NOAUTOlog)) or (SHUTDOWN)
17:25:47 START (COLD DRAIN NOAUTO)
17:25:47 Start ((Warm|Force|COLD|CLEAN) (DRain) (DIsable) (NODIRect)
17:25:47 (NOAUTOlog)) or (SHUTDOWN)
Seems like it does not recognize the START command.

Re: IPL VM/VM Issues
Shorter still:
?l2=length(diag(00))>40 /* We're running a 2nd level VM */
Then something like: If ?l2 then ... some 2nd level stuff...

Re: IPL VM/VM Issues
To determine if you are running under 1st level VM or another level, us
this in your PROFILE EXEC (REXX):
/* Determine what level of VM (VM under VM) we are running */
Parse value Diagrc(0) with rc 10 . 11 cc 12 . 17 D00Data
FirstLevel=(Length(D00Data)<=40)
MyLevel=Length(D00Data)/40

As others have pointed out, your L2 guest can't hurt your L1 system or
other guests unless L2 has access to those disks. Stating it from a
different angle - you should never give your L2 guest access to anything
you don't want it to have access to. It's no different than keeping
your
z/OS and Linux guests from stepping on each other or your L1 system.
This
guest just happens to be running VM.
For your IPL, if you've DDR'd your SPOOL volumes from L1 to L2, there is
no reason to do a COLD start. Do a FORCE start instead. Otherwise you
need to rebuild or SPXTAPE LOAD the SDF files.
For TCP, what happens depends on what you have set up for your L2 guest.
If you gave it access to a real hardware (OSA, hipersocket, etc) then
you
have other work to do to prevent IP conflicts. If instead you've given
it
access to a disconnected VSWITCH and/or virtual LAN, then it won't cause
any problems because it can't connect to anything. And, yes, defining
GRAFs and using DIAL is a standard practice.
Something you might want to look into is setting up your system so it
recognizes whether it's at L1 or L2 or at DR so that it does the "right
thing" for that situation. There's several ways to do that, but you've
gone down the path of diverging your L2 system from your L1 system. At
my
site I have it setup so that I can DDR my L1 system into my L2 guest,
into
a couple different setups at my DR site, or into some unknown site, and
it
comes up the way I want it to in each instance even if the others are
running. It makes life easier. What you're doing is a great learning
experience, and eventually you'll see the value in making your multiple
systems easier to manage.
