How are you adding your LUN to the ESXi? make sure you are enabling the SSP, and enable it. Then from the SSP assign the LUN which you have created to the HBA WWN of the ESXi Server.
It should work without any issue, I have used it with 4.0 ESX and ESXi as well

I resolved the issue myself.
First of all I noticed that all expansion in the array has been finished (yesterday there was an array expansion in progress)
Then I modified the Hostmode of the LUN: ctrl wwn="500805F3001AE2B9" modify ai=500508B200C81A73 hostmode=Linux
Now the attach has been successful.
Thanks all for the support!!
