Upgrade UCS E-Series software

[SIMMN]

I have a UCS E module running inside ISR router chassis and firmware is 3.1 currently. I am planning to upgrade it to 3.2.7 but got confused on if I need to use the Host Upgrade Utility OR just use the Firmware Management options in CIMC?

All Cisco docs seem point to use HUU but what would be the downside of using the firmware management within CIMC Web UI?

Greetings.

The HUU ISO can also contain firmware for the NICs, raid controller, HDDs, etc.

The web method only provides updates for the CIMC and BIOS.

Perfect, I am clear now!
