Abstract
A direct-attached storage device software RAID crash dump system includes a chassis housing a software RAID subsystem coupled to physical storage devices, controller devices, and a hypervisor subsystem. The software RAID subsystem presents a primary controller device to the hypervisor subsystem as being connected to a logical storage device provided by the physical storage devices. When the software RAID subsystem receives a first crash dump command from the hypervisor subsystem directed to the primary controller device and identifying a crash dump logical storage subsystem in the logical storage device, it transmits a respective second crash dump command to each of a subset of the physical storage devices that provide the crash dump logical storage subsystem via a respective controller device that couple the software RAID subsystem to that physical storage device, confirms completion of the respective second crash dump commands, and transmits a crash dump confirmation to the hypervisor subsystem.
