Automatic Load for a Logical Partition
If you want the control program to be loaded automatically each time the LP is
activated, select the Load during activation checkbox. Use the Customize/Delete
Activation Profiles task available from the CPC Operational Customization tasks list
to open a image profile. The Load during activation selection is located on the Load
page for the LP. See Figure 3-26 on page 3-75.
Coupling Facility Logical Partitions
Do not support automatic load because the coupling facility control
code is automatically loaded and made operational at LP activation.
No IPL of an operating system is necessary.
z/OS LPs Specify parameter (PARM) information if desired. Byte 2 and byte 3
of the PARM field are used to select an IOCONFIG member for this
IPL if you do not want the default (00).
Defining Logical Partitions
Before using this section you should first read “Determining the Characteristics” on
page 3-5. This section describes the panels, parameters, and tasks, you can use to
define LP definitions.
Sample tasks and panels explained in this section reference tasks and panels
available from the support element console of a System z9. However, detailed
procedures for operator tasks and accurate task and panel references are left to the
appropriate operator guides. See the Hardware Management Console Operations
Guide and Support Element Operations Guide .
LP definitions are saved across a power-on reset and are used during each
power-on reset. You can use reset, image, and load profiles to modify LP
definitions. Use image and load profiles to modify LP definitions after the CPC has
been activated. Use the Customize/Delete Activation Profiles task available from the
CPC Operational Customization tasks list to open a reset, image, and load profiles.
You can change reset, image, and load profiles at any time. However, some of
these definition parameters cannot affect the running system if the affected LP is
currently activated. See “Changing Logical Partition Definitions” on page 3-84.
LP definition parameters fall into the following categories:
Global reset profile definitions
v
Processor running time
v
Automatic I/O interface reset
v
LP automatic activation order
v
Enable global input/output I/O priority queuing
General
v Logical partition identifier
v LP mode of operation
v Enable logical partition time offset
Processor characteristics
v Dedicated or shared general purpose CPs
v Internal dedicated or shared coupling facility (ICF) CPs
v Initial, minimum, and maximum weight
v
Weight capping
