Abstract
A method is provided for controlling a redundant array of independent disks (RAID). The method comprises a computer system writing data to a RAID and reading data from the RAID, wherein the RAID includes a controller and a plurality of data storage devices, including a flash data storage device. The method further comprises the controller detecting whether or not the flash data storage device is in read-only mode, and the controller preventing attempts to write data to the flash data storage device in response to detecting that the flash data storage device is in read-only mode. Optionally, when the flash data storage device is in read-only mode, the controller may redirect writes intended for the flash data storage device to empty data storage space on another data storage device or cache memory, or modify the parity stripe of a major stripe in view of the data intended to be written.
