IEP_support,   Would you confirm a few things for me?   What version was the BIOS and iDrac prior to the update?   Is the server connected to a KVM, if so does issue persist when removed and directly connected?   When you powered down and pulled the cables, did you also clear the NVRAM with the jumper? (as seen on page 178 here)   Have you taken it to its minimum to post configuration? (page 181 of guide linked above)   Let me know what you see.    
Hi all, I've been upgrading our R630s iDRAC and BIOS to v2.83.83.83 and v.2.16 respectively. I went to rebuild an ESXi host and made the change from BIOS to UEFI boot. Now the server is stuck on 'initializing firmware interfaces' on boot. I've tried unplugging all drives, unplugging all peripherals, pressing and holding the power button for 30secs with the power cables out, tried rolling back to an earlier iDRAC firmware version etc etc etc.    The Lifecycle controller seems to go between being in recovery mode, to being fine, to being unavailable. I can't issue any keyboard commands to get into the BIOS without the server being stuck initializing firmware interfaces.  Anything I can do with RACADM or is this server cooked?
