Partitions page in the AIX PowerVM view

PowerVM partitions

The PowerVM Partitions table lists all PowerVM partitions present in the selected frame. By default, some columns are hidden. You can show or hide columns using the action menuthat is located next to the Allocated Capacity table title. For more information, see Managing-charts-and-tables-in-Views. 

Each row corresponds to a PowerVM partition and shows the following information.

PowerVM partition details

To view the details page for a particular partition, click the name of the partition in the Partitions column. The Partition details page displays the following information:

• General details: General partition details, such as name, type, description, number of elements within it, and tags are displayed at the top of the page. 
• Related Information panel: Displays links to detailed pages for Thresholds and Partition details.
  • Thresholds: The thresholds page allows you to view and manage threshold settings for the selected Pool. See Configuring-and-managing-thresholds-for-metrics-and-indicators for detailed information.
  • Partition details: Click to view the .
• Tags panel: Displays tags (if any) that are associated with the pool. For more information, see Filtering-data-displayed-in-Views.

• Summary information: The Summary tab displays performance details for the selected pool in a horizontal summary table as well as charts.

  You can download charts, annotate them, print them, and so on. For more information, see Managing-charts-and-tables-in-Views.  

• Configuration Details: The Configuration Details tab displays the configuration metrics for the pool.
• File Systems: The File Systems tab displays information related to the file system for all partitions or the selected partition.
  
• Donated CPU Busy/Idle and Active Virtual Processor charts

Available memory

Review the Memory Available chart on the Partition details page to view the amount of memory available for use by processes. This metric is available for AIX 7.1, AIX 6.1 (TL2 or higher) and AIX 5.3 (TL9 or higher) systems. AIX computes available memory by taking into account the amount of free memory and the minimum memory needed for the file system cache.

Donated CPU Busy/Idle

Review the Donated CPU/Busy/Idle chart on the Partition details page to understand whether the selected DLPAR is donating CPU cycles periodically.

If the DLPAR is always donating the same amount or never donating cycles, then a processor reconfiguration may be a better option than Shared-Dedicated mode.

This chart will be displayed if Shared-Dedicated mode is enabled for DLPARs. If the selected DLPAR donates cycles to the Pool, the chart will display the number of donated cycles.

Active virtual processors

The Partition details page described in the preceding section contains an Active Virtual Processors chart with an Hourly resolution. You can use this chart to understand how many virtual processors are active during peak load, and also to scale up or down the number of configured virtual processors.

Processor Folding causes the hypervisor to reduce the number of virtual processors based on the load on the system. This improves the efficiency of the system by reducing the overhead of running additional processors and also avoiding unnecessary context switches.

File Systems information

The File Systems tab has a summary table that displays the following information related to the file system for all partitions or the selected partition.
