Abstract
A storage system with an array of redundant storage devices places bounds on access request servicing. If a storage device is unable to service the access request within the bounds, the storage system temporarily, individually offlines the specific storage device. Access requests pending for the storage device may be serviced by other storage devices of the redundant array while the storage device is offline. The offline storage device can perform error recovery and be brought back online by the system when error recovery has completed.
