Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Complex computing systems face disruptive device failures, leading to inefficient hardware recovery processes that require manual intervention and system restarts, causing downtime and service disruptions.
Innovation Solution
A mechanism to automatically detect hardware errors and place the system in a specific sleep state based on the faulty component type, allowing for replacement without restarting or rebooting, using systems, methods, and non-transitory computer-readable storage media to manage the sleep state and component replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual hardware recovery process is used to replace failed components, then system reliability is improved, but system downtime increases and service disruption occurs
Solution Approach 1:
The system performs preliminary actions by automatically detecting hardware failures and placing the system in an appropriate sleep state before the actual component replacement occurs. This preparation eliminates the need for manual intervention and system restarts, enabling seamless hot-swapping of components while maintaining system reliability and minimizing downtime.
2Ease of repair
If system is powered down to replace hardware component, then component replacement is simplified, but service disruption increases and recovery efficiency decreases
Solution Approach 1:
The system changes its operational parameter by transitioning to a sleep state that maintains certain system functions while allowing safe component replacement. This parameter change enables automated recovery processes and hot-swapping capabilities, improving both ease of repair and productivity by eliminating the need for complete system shutdowns.
3Device complexity
If hot-plug support is not available, then system complexity is reduced, but hardware recovery becomes less efficient and requires manual intervention
Solution Approach 1:
The system introduces an intermediary mechanism by implementing automated failure detection and sleep state management that bridges the gap between systems without hot-plug support and modern automated recovery requirements. This intermediary layer enables automated component replacement and compatibility verification, increasing the extent of automation without significantly increasing overall system complexity.

AI summary
Systems, methods, and computer-readable storage media for hardware recovery are disclosed. In some examples, a system can detect a hardware error and identify a system component associated with the hardware error. The system can then generate a request configured to trigger an operating system of the system to place the system in a particular operating state. The particular operating state can be determined based on a component type of the system component. The particular operating state can be a first sleep state when the component type is a peripheral component or a second sleep state when the component type is a processor, a memory, or a power supply. The second sleep state can result in a lower power resource consumption than the first sleep state. The system can generate an indication that the system component can be replaced without restarting the operating system.
