That's a simple no. The only issue i can think of is an ASR trigger where the software thinks the system is hanging and gives the ILO a server reset.

Re: If Management Processor embedded & ilo Failed does affect my System Operating System?

I had an iLO fail on me and it cause some issues with the fans and cooling.  The server would over heat a few minutes after booting up because of the iLO not properly controlling things and the OS would eventually crash:

We upgraded the iLO 4 firmware on a DL360p Gen8 with no errors or problems.  Some time later the server shutdown.  After booting back up, we get these errors at post:

iLO 4 not responding.  System Health Monitoring has been disabled

1500 iLO 4 configuration is temporarily unavailable (5).

Re: If Management Processor embedded & ilo Failed does affect my System Operating System?

The server would boot up and would run for maybe 10 or 15 minutes before shutting off.  If you put your hand on the cover of the server, it was so hot it was painful.  We had to dump the server because we could not fix the iLO and it was out of warranty.  I tried booting up to a bootable HPE firmware ISO to try to force the iLO firmware to be updated, but that did not work - the boot ISO acted really funny - it would hang at various points during the load/boot up...I think because it was overheating.  I also tried using a large barn fan to keep the server cool long enough to fix - but that ended up not helping either.

I also tried flipping the iLO switch on the system board and pulling out CMOS battery.  Nothing worked.  And all this happened when we did a simple iLO firmware update.  The update completed sucessfully with no errors.  A short time later..bam! The server shut down on us.

I dont recall if there were any ASR errors....its been over a year since this happened.  The main thing we saw (besides the overheating) was this during bootup:

iLO 4 not responding.  System Health Monitoring has been disabled

1500 iLO 4 configuration is temporarily unavailable (5).
