RE: IPL for delayed PTF, shutdown to activate firmware



fixed

So all I need is a PWRDWNSYS RESTART(*NO), all partitions.
Shutdown the service processor.
All firmware will now be activated.
Start the service processor.
Start all the partitions.
PTFs will apply on the way up.

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:
<http://pic.dhe.ibm.com/infocenter/iseries/v7r1m0/topic/cl/pwrdwnsys.htm>
_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 PwrOff.?
