Dell 11-12th gen 710-720 firmware update observations

I have recently been playing around with a new install of the Dell Management vCenter plugin version 1.6. Very nice tool. Should save TONS of time. I also had to learn a bit about the server's firmware upgrade process now that the LifeCycle controller is involved. Here are a few things. Again this is either r710 or r720. I have been using both a lot lately.

This error after a PERC firmware update:
PR1 PERC replaced part detected
This message is safe to ignore either way.
Enter lifecycle controller from the boot menu, and run an inventory to clear the message.

I forget which update did this, probably the NIC firmware. The machine would not boot. The message was:
"Plug and play Configuration Error:
Option ROM Shadow RAM Allocation error."

The fix is to go into the NIC BIOS and disable all option ROMS for every NIC. Too many loading can cause this as there is not enough Shadow RAM to hold them all if you have many NICs. They apparently all get enabled with the firmware update.

I will post more as I find them.
Hope this helps someone
