If the disk volume is configured as RAID 0 or JBOD and one or more of the hard drive
members are disconnected or unplugged, you can plug in the same hard drives into
the same drive slots and use this function to recover the volume status from “Not
active” to “Normal”. The disk volume can be used normally after successful recovery.
