Abstract:
1. An apparatus for controlling a solid state disk comprising: a processor; and a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to: detect, by a failure detector, a failure in the solid state disk; responsive to the failure detector detecting the failure, set by a status degrader, a degraded status indicator for the solid state disk; and responsive to the status degrader setting the degraded status indicator, maintain, by a degraded status controller, the solid state disk in operation in a degraded operation mode; while maintaining the solid state disk in operation in the degraded operation mode, the solid state disk remains online and able to handle SCSI commands which do not access the media within the solid state disk so that non-media commands are executed by the solid state disk to gather information about the cause of the failure.
