Does anyone use a Dell PERC H730P or similar RAID controller in RAID mode?
I have several NetBSD systems with PERC H730P's
mfii(4) says all configuration is done via the controller's BIOS.
Does that mean I need to shut down in case a drive fails an I need to rebuild?
no.
on my systems powerd will notify me of a state change on the disk array,
then I can use bioctl to see the current state. I can then hot swap the
faulty disk and the array will automatically start rebuilding.
Can I monitor the RAID state?
yes.
green-mountain# bioctl mfii0 show
