I have a new server that I installed VMware ESXi 5.1 on. The OS is installed on a thumb drive. The server is a Supermicro SYS-6026T-URF4+ . I have added in a Promise SuperTrak EX8760T RAID card. I am running 8 1GB Enterprise SATA drives off of the card. I configured and initialized a RAID 5 array, and it is running fine. During the install of ESXi I did not see the option to install on the array, but I was going to the USB drive anyway. After completing the install I went to setup a datastore on the RAID volume, but ESXi does not see a volume. I went into storage controllers and I could not see the RAID controller listed as available hardware. If I look in the advanced settings I do see the Promise controller available for pass-through, but I do not want to do that. Any suggestions on how I can get ESXi to see th RAID so I can actually setup a datastore? I have installed the latest patches (12/12). All of my hardware is in the compatibility list for ESXi 5.1.
