Esxi 4.1 Update 1 Dropping Storage?

We have installed Esxi 4.1 U1 with some great assistance from the experts

I went to transfer a VM from our previous server 4.0 to 4.1
The storage is a RAID 10 with 4 x 1TB drives on an Adaptec 3405 controller
The strorage attaches fine and we labelled the storage as "storage1"

I went to copy the vm and was getting errors
In logging into 4.1 with vsphere the storage was gone!
So I recreated it again no problem.
I was able to create directories via the browser, and upload test files no problem.
Then the storage disappears about 2 mins later!
Re scall all - storage is gone

The raid bios indicates the raid is OPTIMAL at 1.8TB

What is happening??

I cannot find the Adaptec 3405 storage controller on the VMware Hardware Compatibility list, unless it uses a different model name I cannot see.

I wondering if ESXi 4.0 or ESX 4.1 would have been a better choice.

Is there a later firmware bios for the storage controller you could try?

How do you get the host to see the storage again  restarting?

I assumee the 1TB are SATA - it is a little known fact that SATA RAID is not supported for VMFS filesystem (while it is for install). However, many folks (including me) use it every day for less critical workloads.

http://www.vmware.com/resources/compatibility/info.php?deviceCategory=io&mode=io_introduction
NOTE: IDE RAID and SATA RAID are not supported for the VMFS file system.

You see the same notes on the hcl at the top of the page when you do any search from the I/O devices page.

All that being said - what are the rest of the specs on the server?

got it - had to register it...thanks for your help!  So in my case VT-d disabling seems to the trick
