spare in case of predictive failure. Use this property in conjunction
with the Allow Revertible Hot Spare and Replace Member property.
Redundant path view Indicates whether Storage Management has detected a redundant
path configuration. Storage Management detects a redundant path
configuration when both controller ports are connected to the
