Configuring an Enclosure Spare Disk
An enclosure space disk acts as a hot spare for all RAID groups within a single enclosure (NAS or expansion
unit). Under normal conditions, the enclosure space disk is unused and does not store any data. When a
disk in any RAID group fails, the hot spare disk automatically replaces the faulty disk.
Important
Storage enclosures (the NAS and expansion units) cannot share enclosure space disks. A
unique spare disk must be assigned to each storage enclosure.

RAID Bitmaps
If a disk is temporarily disconnected from its RAID group and then reconnected, the RAID group must
synchronize all of its data. This process may take a long time. If the RAID group has a bitmap then only
changes that were made after the disk was disconnected need to be synchronized, greatly speeding up the
process.
