Hi!
I have a Microserver G8 with latest HP ESXi image stalled on SD card.
And following problem was found:
If in BIOS settings switch to AHCI usage - on every ESXi reboot disk disappears from ESXi server and every time must be readied - it can be done without any problems - and its working until next ESXi reboot.
If single HDD installed and used as RAID0 array via B120i - everything is OK in ESXi - disk are not disappears from ESXi after reboot
