Program QWCCRTEC: Prints Report on Time Spent in IPL Phases/Steps
There is a program that may be used that generates a spooled file which shows how long the system spent in each of the IPL phases. To find execute QWCCRTEC occasionally or at least after IPLs following abnormal system ending (which forces the 2C40 cleanup) to provide data regarding how long the IPL stays in each phase. There are major differences between doing an IPL on a fast, newer processor and doing an IPL on an older and much slower systemIBM Support
Call this from any command line:
This runs in a second and prints a report.
Use WRKSPLF to check your report
and then Search for “PWRDWN”
Now you can see the exact date and timeline for the power down IPL phase and how long it took to power back up.
