Quick question. If I update BIOS and firmware (e.g. NIC) using OME via the iDRAC, does anything need to be done on the server first? I have several new ESXi R720s that I need to update. They're not running any VMs (they haven't been configured/set up yet) but they are turned on and are at the basic ESXi login screen. My understanding is that the iDRAC will do everything in the background and then only reboot the server once it's finished, so the only downtime is during the reboot. Is that correct?
If the situation changes and the servers do have VMs set up, will anything need to be done before I run the system updates from OME? The iDRACs are all discovered using WS-MAN.
Thanks.
