Dell PowerVault ME5 Series Storage System CLI Reference Guide

For virtual storage, all spares are global spares.

For linear storage, you can add global spares or dedicated spares.

A global spare can replace a failed disk of the same type (enterprise SAS, for example) and the same or lower capacity in any disk group with a fault-tolerant RAID level other than ADAPT. The system supports a maximum of 64 global spares. However, the system will prevent adding global spares if only ADAPT disk groups exist.

A dedicated spare can replace a failed disk of the same type (enterprise SAS, for example) and the same or lower capacity in a specific disk group with a fault-tolerant RAID level other than ADAPT. A linear disk group can have 4 dedicated spares.

If the disks in the system are FDE-capable, spares must also be FDE-capable.

For information about sparing rules, see the spares topic in the Administrator's Guide.
