David,
Now it's clear for me.
It's matter of language - in Polish there is no such gismo like article (a, an, the). Yes, you are right, *assuming proper setiing* it is possiblem to control other domains from a TKE. AFAIK, it's not possible to do it from z/OS. However there's a trick: changing usage domain (or just have an LPAR with several domains) and restart ICSF with another domain ID.

From the otheer hand it's IMHO better to explain something to someone, than sho the things are more complex. Some simplifications are sometimes justified ;-)


BTW: Has anybody heard about RCE? Regional Crypto Enablement. A card, defined in HCD as a function. Available in z13 GA2.

RS,

I should have elaborated more.  You need *a* system up and running on the box, 
but not *the* system.   For example we use TKE, and connect to a TECH system on 
the box that is running.   That tech system IMAGE profile is setup to be able 
to administer all crypto domains.   So when we bring in a new box, we ipl a 
tech system onto it, and then we can reload MK's for all domains, including 
systems that are not yet operational.  If there is a new MK waiting to load in 
the crypto card register, ICSF will load that MK automatically upon 
initialization.

I don't believe that there is a way to load MK's for other domains via the ISPF 
panels, but I could be wrong.

Well, again, this is straightforward approach: you have your own (or
dedicated) DR machine. You prepare your system for DR, part of preparation can 
be MK entry. That means *some* z/OS system IPL-ed, preferrably a copy of your 
prod system.
@David, AFAIK even with TKE station you have to IPL the z/OS...

Of course, if the machine is to be reused by other company, then leaving MK is 
not the best idea.

If you have a TKE, then you can load it in advance.  If not then your only 
option is to use the ISPF based ICSF panels.

Thanks. I'm on board except for this statement. "You can do [the Master Key] in advance or 
during DR IPL." What is "in advance"? These systems are IPLed only in DR (test) 
mode. Is there any alternative to actual IPL?
