HDD Rebuilding Control with Password Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a second HDD is newly attached in a state where a first HDD is already attached, rebuilding is automatically initiated for the newly attached HDD before a password is set, leading to potential data access issues.
Innovation Solution
An information processing apparatus that sets the initial rebuilding function to OFF, generates a password for the second HDD, and transfers the system to a mirroring mode, preventing rebuilding until the password is set, thereby ensuring secure data access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rebuilding is automatically started when a second HDD is newly attached, then data redundancy is improved, but data security deteriorates because the HDD is accessible without password protection
Solution Approach 1:
The system performs preliminary password setting before initiating the rebuilding process. When a second HDD is newly attached, the control unit first sets a password for the HDD, then starts rebuilding. This ensures that the HDD is protected with password authentication before any data operations occur, preventing unauthorized access during the vulnerable rebuilding phase.
Solution Approach 2:
The system dynamically adjusts the rebuilding initiation condition based on the password setting state. The control unit monitors whether a password has been set for the newly attached HDD and only initiates rebuilding when the password is successfully configured. This dynamic control mechanism ensures that rebuilding never starts in an insecure state, resolving the contradiction between automatic redundancy and security protection.
2Object-affected harmful factors
If a password is set for the newly attached HDD, then data security is improved, but the complexity of the operation increases
Solution Approach 1:
The system provides self-service password generation and setting functionality. When a second HDD is newly attached, the control unit automatically generates a password and sets it for the HDD without requiring manual user intervention. This automation eliminates the need for users to manually configure passwords, reducing operational complexity while maintaining strong security protections.
Solution Approach 2:
The password setting operation is merged with the HDD attachment detection and rebuilding initiation processes. The control unit combines these three functions into a single integrated workflow: detect new HDD attachment, automatically set password, then initiate rebuilding. This consolidation reduces the number of separate user actions required and simplifies the overall operation while ensuring security is maintained.

AI summary
An information processing apparatus connected to a first storage device and a second storage device via a storage control device, the information processing apparatus includes a transfer unit configured to cause the storage control device to transfer to a rebuilding state after the setting unit has set the password for the second storage device.
