They kick their drives offline. Dell has a firmware update but we haven't had a chance to install it just yet to see if it fixes the problem with that one. > That said, I consider the rebranded LSI cards a pain and hate the quality of > Dell's hardware. Yeah, I'd just as soon get a regular LSI bios as the remade one Dell seems intent on pushing. Also, we just discovered the broadcom chipsets we have in our Dell 1950s and 1850s will not negotiate to gigabit with our Nortel switches. Everything else I've plugged in just worked. Went looking at Dell's site, and for the 1950 they recommend buying a dual port Intel NIC for it. Why couldn't they just build in better NICS to start?
