In the Unit Maintenance section, this link isonly provided for drives that can be safely removed without creating aninoperable unit. (For example, a RAID 5 missing 2 or more drives or a RAID0 missing 1 or more drives would become inoperable.) If you remove a drivefrom a redundant unit, the unit will become degraded. Once a unit has becomedegraded, additional drives cannot be removed without making it inoperable,so no Remove Drive link will display.
