Storage Control Device Automatic Identifier Update
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing storage systems, active replacement of non-volatile memory devices increases the workload and error rate for operators, as they need to manually update identifiers for the devices, which can lead to incorrect updates and increased manual labor.
Innovation Solution
A storage control device that associates actual identification information of a recording medium with virtual identification information, allowing for automatic conversion and updating of identifiers when a device is replaced, reducing the need for manual intervention and minimizing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual updating of device identifiers is performed during active replacement, then device replacement can be completed, but operator workload and error rate increase
Solution Approach 1:
The storage control device automatically detects device replacement and updates identifiers without operator intervention. The system monitors slot status changes and autonomously manages the identifier update process, eliminating manual workload and reducing errors.
Solution Approach 2:
The system continuously monitors slot status and device presence, using this feedback to trigger automatic identifier updates. When a device is detected as replaced, the system responds by automatically updating the identifier association in storage, creating a closed-loop automation process.
2Reliability
If manual updating of device identifiers is performed during active replacement, then device replacement can be completed, but error rate increases due to incorrect updates
Solution Approach 1:
The storage control device autonomously performs identifier updates by detecting device presence and automatically associating the correct identifiers. This eliminates human error in manual updates while keeping the replacement process simple for operators.
Solution Approach 2:
The system introduces an automatic identifier management intermediary that sits between the physical device replacement and the logical identifier association. This intermediary automatically matches devices with their identifiers, preventing incorrect updates while maintaining operational simplicity.
3Extent of automation
If virtual identification information is associated with actual identification information, then automatic conversion is enabled, but system complexity increases
Solution Approach 1:
The patent introduces a virtual identification information layer as an intermediary between the host and actual devices. This abstraction layer enables automatic conversion and protects the host from device replacements, while the complexity is contained within the storage control device rather than propagating to the host system.
Solution Approach 2:
The system creates virtual copies of device identifiers that the host interacts with instead of actual device identifiers. These virtual identifiers can be automatically updated to point to different actual devices, enabling automatic conversion without exposing system complexity to the host.

AI summary
A storage control device, includes a memory; and a processor coupled to the memory and the processor configured to: when receiving a first response that includes first information from a control device, generate a second response that includes second information by converting the first response, transmit, to a host device, the second response, and when detecting that a first recording device is removed from a slot and a second recording device is mounted in the slot, update, by using the first information of the first recording device associated with the second information, the first information of the second recording device.
