The Operating System Layer

Using the tests mapped to this layer, you can:

• Determine the total physical resources available with the pSeries host;
• Understand how all the LPARs have collectively utilized the physical resources;
• Detect resource contentions, if any, at the host-level, and what is causing them;
• Monitor the VIO server so that, you can isolate the logical volume storage pools of the VIO server that are running short of space, determine the current state of the volume groups on the VIO server, and analyze the I/O activity on the storage adapters and attached disks on the VIO server;
