Direct-attached storage device software RAID hibernation system

An Information Handling System (IHS), comprising:

• a storage controller processing system;
• and
• a storage controller memory system that is coupled to the storage controller processing system and that includes instructions that, when executed by the storage controller processing system, cause the storage controller processing system to provide a filter engine that is configured to:
• identify, while in a runtime mode, a controller initialization request from an operating system that requests initialization of a storage controller device that includes the storage controller processing system and the storage controller memory system and that controls at least one of a plurality of physical storage devices that provide a logical storage device;
• and
• transmit, to a bus driver subsystem while in the runtime mode and in response to identifying the initialization request, a power-down prevention communication that is configured to prevent the bus driver subsystem from powering down the storage controller device during a hibernation mode.

A method for providing for hibernation in a software Redundant Array of Independent Disk (RAID) using direct-attached storage devices in a computing device, comprising:

• presenting, by a software Redundant Array of Independent Disk (RAID) subsystem to an operating system while in a runtime mode, a primary controller device in a plurality of controller devices as being connected to a logical storage device provided by a plurality of physical storage devices;
• identifying, while in a runtime mode by a filter subsystem that was provided by the software RAID subsystem on a secondary controller device that controls at least one of the plurality of physical storage devices, a controller initialization request from the operating system that requests initialization of the secondary controller device;
• and
• transmitting, by the filter subsystem to a bus driver subsystem while in the runtime mode and in response to identifying the initialization request, a power-down prevention communication that is configured to prevent the bus driver subsystem from powering down the secondary controller device during a hibernation mode.
