I have an HP ML370 with a P400 raid controller installed. It has 6 disks in a raid 5 config. 5 active disks and a 6th spare. The ACU is reporting a SMART predictive failure event for one of the 5 active disks (the server is working normally currently).
My questions are, do i assign the spare disk in the ACU to the array? what will happen to the array when i do this? will the spare be automatically included in the array once assigned and how will i know when it is safe to remove the disk that has the predicted failure?
