There's your problem. :-) I have nothing good to say about DELL, and what I could say, well it's nothing I can print in a public forum that wouldn't be expletive laced. "Real" LSI, or IBM/Lenovo branded LSI raid cards don't restrict their users in such a fashion. I've taken IBM branded drives out of a failed IBM/LSI controller, imported them into a genuine LSI controller, and then ran it for years before the machine became too old and was replaced. It's telling when you take the IBM stickers off their LSI raid controllers and you see the original OEM markings still on the card. Add to that how easy it is to reflash 'genuine' LSI firmware on the IBM cards and the cards run slightly faster because all IBM apparently inserted into the controller BIOS was interface code for the BMC & IMM. :) Try doing that with a PERC card. :P -- Drew -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
