If you run HP G7, Gen8, or Gen9 servers and boot ESXi from SD card you may run into an issue/bug with certain HP iLO versions.  The issue causes the SD card to lose connectivity to the system.  This does not affect the host or VMs since VMware loads itself into memory, but will cause issues with management of the host.

I have dealt with this issue on and off for several months and here are some of the fixes you can try.  Ultimately, you want to patch your iLO to version without the issue but in a pinch these options will help you bring the host back into compliance.
