An exiled drive is one that is considered as unreliable by firmware, banished from a logical drive, and then powered down. Banishing and powering down an unreliable drive helps ensure array performance. If a drive is manually disbanded from a logical drive, its status will be indicated as “Exiled.”
Disk Reserved Space Recovery may recover such Exiled Drives as well as others labeled as Bad, Used or possible even those marked as Missing.
