RAID level 5 is creating stripes with parity and data distributed across all disks. If a disk fails, the data on the failed disk can be rebuilt from the distributed data and parity information on the other disks.
Within Enhanced Storage, a RAID 5 volume is a volume that supports RAID Level 5.
Enhanced Storage automatically initializes a RAID 5 volume when you add a new slice, or resyncs a RAID 5 volume when you replace an existing slice. Enhanced Storage also resyncs RAID 5 volumes during rebooting if a system failure or panic took place.
RAID 5 volumes have names like other volumes (d0, d1, and so forth).
