If your site records SMF records, and if your site records SMF type 0 records, then you can use them to generate what you want. However, accessing SMF records is not a simple task since they have bit-level fields that must be interpreted correctly.

Hello,

If you have proper permission you can copy these records from the SMF data to a file of your own using your sort product and only INCLUDE the records you want.

This is the easy part. . . Keep in mind that there is a Huge volume of SMF data. Also keep in mind that you will have to write code fo the info you want from the selected SMF records.

Suggest you talk with the system support people as they may already have the info you want reported already.

with the current MTF reporting on IPLs is just waste of time.
nowadays an IPL in a production system is kind of a traumatic event.
with quite a bit of paperwork and follow ons.

if Your organization has the need to track the IPLs then, most probably, has bigger problems hidden somewhere.

If this does not have to be for the past then you can record your IPLs using a rexx called IPLPARM or the something like that, IPLPARM can be found at
http://www.mzelden.com/mvsutil.html

We have a job that runs every day at 23:55 to document the IPL information.

Technically, the SMF 0 record does not record IPLs; it records the start of SMF recording, though that usually amounts to the same thing.

Technically it should be fine to track via SMF, but I am sure there should be change record for all the scheduled IPL's and also Emergency IPL reported to Change Management Post the IPL.

The System Management Facilities (SMF) manual has
13.4 Record Type 0 (00) -- IPL
so IBM says the record is for IPL.

Robert - you should read more of the chapter, not just the chapter title. Fair use excerpt --
Record type 0 is written after every SMF initialization. It includes the virtual and central storage sizes and some of the SMF options in effect. See record type 90 (subtype 9) for information about the IPL of SMF.
My emphasis.
