First of all thanks for help me out with this issue, this is the situation as you know the ucs comes with a an Intel ICH10R onboard SATA controller on the motherboard which does not support the use of the integrated software RAID with the ICH10R controller in order to install esxi with redundancy. I did the installation of esxi 5 in both hard drives without any array to check that everything was working fine and the installation was successful, then I ordered the LSI 1064-based controller mezzanine card. This card provides RAID 0, 1, and 1E support for up to four SAS or SATA drives in order to install esxi with redundancy, I installed the card on the board, when the ucs boot and I enter on the lsi setup I can't see my hard drives(2 Sata), thus I can't create the Raid 1.
What should I do in order to fix this issue???
Once again thanks for your help.
