if the system has access to the internet, reboot  the system, press F10 when prompted to enter the LifeCycle controller, then once its in there, select Firmware update, leave FTP server selected and proceed from there, its fairly intuitive. One of the choices will be to update the H710 controller.
Hi everyone, I've a brand new PowerEdge R820 server and I'm not able to update the PERC H710 firmware (21.1.0-0007, A03) to the latest version 21.2.0-0007, A04. I've tried with a bootable DOS USB key with the files inside but the update software just says "no controller detected". The server is online since 2 weeks now so there is no RAID rebuild ongoing and I've tried also with PERC H810 firmware, no luck. Any advice? Thanks  Daniele
