Monitoring the State of Disk Drives
Each disk drive can have two paths, the primary and the backup. (Each M8xxx disk drive is
forced to have two paths.) The two path states are represented separately.

DescriptionPath State
This path of this disk drive has a state other than Up.Degraded
The disk volume or disk path is not logically accessible.Down
