I hope you are doing well.i had an issue on Esxi 6.5 there was power cut when power was on host failed to boot with this error
Error loading /jumpstrt.gz
Fatal error: 10 (out of resources)
i am using Dell R730xd servers
The error (Fatal error: 10 (out of resources)) makes me believe you have a hardware problem. You sure all HW is ok? Especially memory?
