capped, and uncapped. The Mem and the InU columns show the configured and in use memory, respectively, measured in gigabytes. The Lp column show how many logical processors are configured. In Example on page 329, all partitions have one virtual processor with SMT enabled and so have two logical processors. The Us, Sy, Wa, and Id columns show the percent user, system, wait and idle times. The PhysB column is the same as in the summary section. The Ent, %Ent, Vcsw, and PhI columns are only applicable to shared-processor partitions. The Ent column shows the entitled capacity, the %EntC shows the percentage of the entitled capacity used, the Vcsw shows the virtual context switch rate, and the PhI column shows the phantom interrupt rate. Typing the letter g in the topas command window expands the global information, as shown in Example 5-29. A number of fields are not completed in this example, such as the total available memory. These have been reserved for an update to this command that will allow topas to interrogate the HMC to determine their values. It is possible to manually specify some of these values on the command line.
