Secondary OS device unlocking system

An Information Handling System (IHS), comprising:

• a processing system;
• and
• a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a Basic Input/Output System (BIOS) that is configured, during initialization operations, to
• send, to a remote access controller device, a request to unlock a storage device using a storage device locking key that is stored in a key management system;
• determine, in response to a timeout condition being satisfied after the request was sent to the remote access controller device, that the storage device is locked;
• retrieve, in response to the storage device being locked, secondary OS information for providing a secondary OS;
• boot using the secondary OS information to provide the secondary OS that is configured to:
• retrieve the storage device locking key;
• unlock, using the storage device locking key, the storage device;
• and
• perform, subsequent to unlocking the storage device, a reboot operation;
• and
• retrieve, following the reboot operation and from the storage device that was unlocked by the secondary OS, primary OS information for providing a primary OS;
• and
• boot using the primary OS information to provide the primary OS.

A method for providing device unlocking via a secondary Operating System (OS), comprising:

• sending, by a Basic Input/Output System (BIOS) to a remote access controller device, a request to unlock a storage device using a storage device locking key that is stored in a key management system;
• determining, by the BIOS in response to a timeout condition being satisfied after the request was sent to the remote access controller device, that the storage device is locked;
• retrieving, by the BIOS in response to the storage device being locked, secondary OS information for providing a secondary OS;
• booting, by the BIOS, using the secondary OS information to provide the secondary OS that is configured for:
• retrieving, by the secondary OS, the storage device locking key;
• unlocking, by the secondary OS using the storage device locking key, the storage device;
• performing, by the secondary OS subsequent to unlocking the storage device, a reboot operation;
• retrieving, by the BIOS following the reboot operation and from the storage device that was unlocked by the secondary OS, primary OS information for providing a primary OS;
• and
• booting, by the BIOS, using the primary OS information to provide the primary OS.
