Automated WWN Registration for Live Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual process of setting migration WWNs for live migration in computer systems is labor-intensive and prone to errors, especially when dealing with multiple LPARs, as it requires manual intervention with storage management software and hypervisor management software, increasing the risk of incorrect WWN settings and unintended access to storage units.
Innovation Solution
A management computer system that automates the registration and deletion of migration WWNs by acquiring and managing WWN information from hypervisor and storage devices, reducing the need for manual intervention and minimizing errors through automated processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual setting of migration WWN with storage management software is used, then the migration WWN can be set in the storage device, but much workload is required for every shifting LPAR
Solution Approach 1:
The system performs self-service by automatically acquiring migration WWN information from the hypervisor and registering it in the storage device without manual intervention. The management computer autonomously completes the WWN setting process that previously required manual operations with storage management software.
Solution Approach 2:
The management computer acts as an intermediary between the hypervisor and the storage device. It acquires migration WWN information from the hypervisor and automatically registers it in the storage device, eliminating the need for manual operations and reducing workload.
2Ease of manufacture
If manual setting of migration WWN is performed, then the migration WWN can be configured, but the risk of incorrect settings and unintended access increases
Solution Approach 1:
The system eliminates manual configuration errors by performing self-service. The management computer automatically acquires accurate migration WWN information from the hypervisor and registers it in the storage device, ensuring setting accuracy and preventing unintended access.
3Ease of operation
If automation is introduced to reduce manual workload, then the setup process is simplified, but system complexity increases
Solution Approach 1:
The management computer performs multiple functions: it manages LPAR migration, acquires WWN information from the hypervisor, and registers WWNs in the storage device. By consolidating these functions in a single system, the patent simplifies the overall operation while managing complexity centrally.

AI summary
The purpose of the invention is to simplify the work of setting migration WWNs used in live migration of LPARs. Hypervisor management software of a management computer acquires and stores, in a storage unit, WWNs set for logical FC-HBAs of hypervisors of computers and host information including a WWN of a source capable of accessing a logical unit (LU) of a storage device. The hypervisor management software uses such information as a basis to output, on a display screen, information indicating whether or not a migration WWN, which is a WWN value of a logical FC-HBA used at migration of a virtual computer of the computer, is in a state of being able to be used to access the LU.
