Hello,
i had the same issue with my DL980 G7, at first the log said vNIC error, then I did some other research on the web, changing the RAID configuration fixed this problem. I had it set to RAID 50, after changing it to RAID 10, it completely loaded. I also have the same problem with the DL380 G7, hope this fixes the issue as well.
The ESXI HPE 6.0 image worked fine, but I also tried installing 6.5 and 6.7, both red screened. My next plan is try to upgrade, otherwise, I will need to build a custom ESXi the drivers for 6.5 or 6.7.
