I need to an IPL for delayed PTF apply.

Am I correct that a shutdown will not apply PTFs?
Do I need to do a restart *yes for the PTF apply followed by a
shutdown to activate firmware.
It is the IPL, rather than the shutdown, in which PTF apply
processing runs. In a manual IPL the PTFs are applied only if chosen to
do so manually from a menu, and in an automatic IPL the previously
identified as delayed-apply PTFs will be applied automatically [at least
if the IPL is not deemed abnormal]. For LIC PTFs, the /side/ on which
the system IPLs is very relevant. Thus the option chosen for the
RESTART parameter of the Power Down System (PWRDWNSYS) should be [and as
I recall, in my experience is] immaterial for PTF activity; i.e. only
the activation of the already-applied firmware updates may depend on use
of RESTART(*NO) having effected a full powered-off PwrDwn. AFaIK the
documentation will suggest RESTART(*YES) as the *recommendation* only
for your convenience; e.g. the following doc:
_i Power Down System (PWRDWNSYS) i_
_IPL source_ (IPLSRC)
Specifies whether an initial-program-load (IPL) is started from the
A-source, B-source or D-source of the system. This parameter allows you
to control which Licensed Internal Code (LIC) storage source of the
system to IPL. Also, the source of the system determines where LIC
program temporary fixes (PTFs) are applied. ...
It is recommended that you specify RESTART(*YES); otherwise, you cannot
be assured which source of the system is actually started. This
precaution can save you some time. ...
FWiW I was under the impression from a prior [somewhat recent;
months] conversation on this forum, that there may be some IPL Attribute
[per CHGIPLA] that might enable the same effect without out the actual
