Defining logical partitions

Edit online

Before using this section you should first read Determining the characteristics. This section describes the windows, parameters, and tasks, you can use to define LP definitions.

Sample tasks and windows explained in this section reference tasks and windows available from the Support Element console. The Hardware Management Console (HMC) and Support Element (SE) information can be found on the console help system.

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 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.

LP definition parameters fall into the following categories:

Global reset profile definitions
  • Enable global input/output I/O priority queuing
  • Automatic I/O interface reset
  • Processor running time
  • LP automatic activation order
General
  • Logical partition identifier
  • LP mode of operation
  • Enable logical partition time offset
Processor characteristics
  • Dedicated and Not dedicated CPs, ICFs, zIIPs, and IFLs
  • Initial, minimum, and maximum weight
  • Absolute capping
  • Number of initial and reserved processors
Security characteristics
  • Global performance data control
  • Input/output configuration control
  • Cross partition authority
  • Logical partition isolation
  • BCPii permissions
  • Counter facility security options
  • Sampling security options
  • CPACF key management operations
Storage
  • Central storage
  • Virtual flash memory
Secure Service Container
  • Boot Selection
  • Administrator user ID
  • Administrator password
  • Network adapters
  • DNS servers
Time Offset
  • Time offset
Load information
  • Load during activation
  • Device type
  • IPL type
  • Load type
  • Validation
  • Load address
  • Use of dynamically changed address
  • Load parameter
  • Use of dynamically changed parameter
  • Time-out value
  • Boot record location
  • Boot program selector
  • OS load parameters
Cryptographic characteristics

  • Assigned cryptos
Note: Coupling Facility partitions cannot take on these characteristics.
Options
