I recently bought a Dell 2850 off ebay. Very clean unit everything powers up etc. It came with 2x 36gb Ultra320 drives, i purchase another 2 73GB u320 drives, and only have one 73 gb in addition to the 2 36gb installed currently, It shows all the drives fine, and i was attempting to put esxi on the machine, it listed all 3 drives so i just picked one of the 36gb and installed it there, however on reboot it don't find the mbr, my question is i thought the 2860 had perc 4 raid card in it, however, i don't see any option to configure any raid. Am i missing something, the only thing that might resemble is the LSI logic controller, but that doesn't have anythig to configure RAID unless I am missing something? any ideas?
