Seems I've figured it out. There is an iDrac settings in BIOS which allows the current configuration to become a valid configuration, once that was checked the device booted like normal.
Hello, running into an issue with a PowerEdge r650. The unit previously had 2 CPUs, going down to one CPU with 96gb of ram. After repurposing via lifecycle, the unit continues to error out with searching for the 2nd cpu. No ram is installed on cpu 2 side. Is there a setting somewhere i need to enable/disable to bypass searching for the 2nd cpu?   Thanks in advance
R650 1 CPU config, still searching for CPU 2
