VMware vSphere 6.5 Install On HPE DL 380 Gen9 install Error：processlookuperror errno 3 no such process
Server:HPE DL380 Gen9 ，Update SPP 2019.12
We had the same problem and by upgrading the BIOS to the latest version, our problem was solved.
Thank you ,i will try !
Try to get the BIOS updated, and also look if there is a special or customized vSphere image for that type of hardware ( search on hp website).
also check on the BIOS settings if HTT is enabled or not it should be enabled by default
