You can't update a PERC 6/i with PERC H700 firmware. It is not a firmware update you need - you need a new/different controller card.
hey i have dell poweredge t710 tower server, when i upgrade Perc 6/i into H800/ H700  its give me the error "This Update Package is not compatible with your system configuration"...... Actually i want to raid 4tb Hard Drive in my server that why i need H800 / H700...  Thanks
