I have a few servers all running CentOS 5/6 some have Software whereas others have Hardware RAID.
With software RAID I check the status of RAID with /proc/mdstat and read /var/log/messages to check if it has any problems.
I am not sure about how to check/monitor the hardware RAID. To my knowledge hardware RAID is presented as one single disk to the Operating System and all sync is done in the background by the hardware.
Can someone please explain?
