2. Occurrence of a fault in PD2
A fault occurs in one of the physical drives configuring a disk array. The disk array enters the
degraded state (the logical drives enter the critical state).
3. The Hot spare rebuild is done by using PD4 to create a logical drive having PD1 and PD4 as
configured HDDs.
4. To add the physical drive PD3 to the original logical drive, select PD3 manually in this state
to run the transition.
