RAID not being recognized on VMWare ESX 5

We had an ESX server that didn't have RAID configured so we moved all VMs from it to another host and wiped everything out, then configured RAID10 in the BIOS.

Now ESX is running properly but we noticed that VMWare is not detecting the new RAID configuration. It only sees the local drives on the server.

I've attached a screenshot of the RAID card installed on the server (using the command "# lspci -vvv"

I've searched VMware hardware compatibility list and it looks to be compatible.

Your screenshot looks like the server does see the adapter.  From the vSphere client, when you select the host, configuration tab, and storage adapters, what do you see for vmhab0?  What other storage devices are listed?

I had a similar issue happen a while back. I had the host mapped to the SAN correctly and when I scanned for the datastores nothing would show. Assuming the host is mapped to the San, scan for updates of the host.

When this happened to me, after I scanned and updated ESX I rescanned the storage adapters and my Datastores appeared.
