Reviewing and adding logical processors

Edit online

Use the Logical Processor Add task to select logical processor definitions to be changed dynamically on the system, in the image profile, or both. Dynamic changes will take effect without performing a reactivation of the logical partition. This tasks allows you to:

Increase the initial and/or reserved values for installed logical processor type(s)
Add a reserved value and set weight and capping indicators for logical processor type(s) that have not yet been installed and have no reserved CPs defined
Increase the reserved value for logical processor type(s) that have not been installed and already have reserved CP(s) defined

The partition status (active and inactive) is indicated in the window title, along with the logical partition name. If the logical partition is active, the current settings are displayed. If the logical partition is inactive, the settings contained in the image profile displays.

Note: Changing the initial value for an installed logical processor type only affects the partition profile for a subsequent activation. In order to dynamically add logical processors to an active partition the processors must be added as reserved and then configured online through the Operating system console.

logical processor add panel — Figure 1. Logical Processor Add task. This is an active partition. There are currently only CPs defined to the partition, so only reserved can be increased for zIIPs.
