When managing a large Power server environment, situations may arise where LPARs need to be migrated between physical servers—for example, when a server requires maintenance.
The Power platform allows seamless LPAR migration, but several factors must be considered, such as:
- Sufficient free CPU resources to accommodate additional workload
- Sufficient free RAM resources
- Allocated Processing Units (Entitled Capacity)
- Shared Processor Pool utilization
In large environments, estimating available space for LPARs on the target server can be a tedious process, often forcing administrators to perform calculations in an Excel spreadsheet.
In the following article, I propose a solution using Grafana and nextract_plus to address this challenge.
