Ignore what I said before. I did more research:
- If the CPC Details window shows "CP Assist for Crypto Functions [CPACF]:
Installed" then CPACF is installed. I believe POR is required if the
feature is installed after delivery, so if the machine is up, the
instructions are available.
- If CPACF is not installed, QUERY CRYPTO will display "No CAM or DAC
Crypto Facilities are installed". [Don't ask.]
- Any other response to QUERY CRYPTO indicates CPACF is installed.

So you have CPACF installed and this jives with the guest's report.

So now you have to figure out why the guest is taking so long. "What
changed?"
Here is a program to tell you if CPACF is installed. Note that the
instructions are part of an architectural group called "Message Security
Assist". CPACF is the name given to implementation, not the architecture.
