If you are trying to update the firmware on the raid card my best suggestion would be to do it through the lifecycle controller. Reboot the server and during post after the Dell splash screen in the top right corner you will see some option via key commands. Hit F10 to boot to system services. Once you've entered the system services/lifecycle controller environment you should be in the gui with a list of options on the left. Choose platform update, follow the on screen instructions to update the firmware for all the components you want, specifically the raid card. I haven't heard of drives being blocked before and I don't know the specifics of the drives you bought, but any we sell should be compatible with what I am assuming is and H-Series raid card you should have in your system.
