NIPCON is a red herring - and has nothing to do with the original post's issue.
The z/OS Console component PINs UCBs. Not NIP. Doesn't matter what is
listed in NIPCON. Not at all.
>From "MVS Planning: Operations" (SA22-7601-06), topic 2.4 Removing Console
Definitions from a Configuration:
-=-=-=-=-=-
(snip)
The following restrictions for removing a console definition apply:
o Dynamic I/O reconfiguration can be performed for a device that has
been defined as an MCS console in CONSOLxx. If you want to change the
I/O configuration of a device which is defined as a console, you must
first delete the console definition.The sample program IEARELCN can be
used to do this. After the definition has been removed, the device
can be dynamically reconfigured, but it cannot be used as a console
again, until a re-IPL. For more information about dynamic I/O
reconfiguration, see z/OS HCD Planning.

Bottom line:
Step 1 - Remove console definition from CONSOLxx.
Step 2 - Do one of the following:
a) Run IEARELCN to dynamically delete the console definition, or
b) IPL
Once you've run IEARELCN or IPLed, the console UCB will not be pinned and an
ACTIVATE will be successful.
