Hardware RAID 5 lost single disk
We are using Red Hat AS 4.5 x86_64 on a Dell 5860. The server has a five disk hardware RAID 5 group. If we lose a disk in that RAID group my unix admins are under the impression the only way to tell is by looking at the blinking lights on the front of the server. I would hope that the hardware would be able to report the disk failure to the OS.
Anyone have experience in losing a single disk in a RAID 5 array? Does it report messages to the OS, or just change the colors of the blinking lights on the front of the server?
