Re: APYPTF vs IPL

APYPTF will only apply those PTFs which are *IMMEDIATE, while doing an
IPL, you will get both the IMMEDIATE and DELAYED ptfs being applied.  In
addition, sometimes even some of the Immediate PTFs will have Pre exisitng
conditions that have to occur before a PTF is active.  If you can afford
to do an IPL, I think you are much better off.

In addition, if you are on a 5xx type box which is NOT HMC managed, and
you apply some of the MH* type of PTFs, then these will not get loaded and
activated into the FSP until the machine is IPLed.  If the machine is HMC
managed, and you have the system set to get the FSP PTFs from a partition,
then the same above applies about loading and activing the PTFs, With the
addition that ALL partitions must be brought down for the FSP to get the
new MH* PTFs installed.
