IPL RESTART: *YES vs. *NO

Is there any difference between doing an IPL with RESTART of *YES vs. doing a RESTART of *NO, and then having to manually power the system back up? We currently do an IPL every Saturday night after doing a "21" save.

Yes. When you power off the system and then manually power it back on, the IPL process spends time restarting all the hardware and performing hardware diagnostics. If you do a PWRDWNSYS OPTION(*IMMED) RESTART(*YES *SYS) only the operating system will be restarted and this is significantly faster.

RESTART(*YES *SYS) is the default used when you specify PWRDWNSYS OPTION(*IMMED) RESTART(*YES) because the PWRDWNSYS command uses the IPL attributes set via the CHGIPLA command.

There is one exception to this rule though. If you are applying a PTF that requires a hardware restart before it can be applied, the IPL is forced to RESTART(*YES *FULL) even if you don't specifically specify it.
