Abstract
A direct-attached storage device software Redundant Array of Independent Disk (RAID) crash dump system includes a chassis housing a software RAID subsystem coupled to each of a plurality of physical storage devices, each of a plurality of controller devices, and an operating system. While in a runtime mode, the software RAID subsystem presents the operating system with a primary controller device from the plurality of controller devices as being connected to a logical storage device provided by the plurality of physical storage devices. In response to entering a crash dump mode from the runtime mode, the software RAID subsystem provides a storage driver subsystem for the primary controller device and uses it to initialize at least one secondary controller device in the plurality of controller devices that controls at least one of the plurality of physical storage devices that provides a boot logical storage subsystem in the logical storage device.
