sys.zOS.LPAR
An LPAR is a logical partition of the physical hardware where an operating system instance can run, for example, z/OS®, z/VM®, and Linux®. The computing platform can operate in either basic mode (non-partitioned) or lpar mode. The LPAR class instance is discovered only if the hardware is operating in LPAR mode. Only an LPAR that runs z/OS or z/OS hosted by z/VM are discovered.
Note: The z/OS DLA supports the CDM V2.9.2 change to use CDM
class ZseriesComputerSystem to represent an LPAR. All LPARs are provided as instances of a
ZseriesComputerSystem object, where Virtual = true. For migration, every LPAR is also provided as an
object of a CDM-class LPAR.
Attributes
| CDM attribute | Value | Example |
|---|---|---|
| Name | Logical Partition name. | ES5C |
| VMID | Logical Partition ID. - Naming rule virtualizes ID. Note: Prior versions of z/OS DLA provided attribute LPARID; the LPAR ID is now shown in
the VMID to match a data model change in CDM 2.9.2.

| MemorySize | 30932992 | |
| ExpandedMemorySize | 30208 | |
| MIFId | The Multiple Image Facility image ID assigned to this particion (also known as partition number). If you are providing the MIFId, provide the LPAR name, too, which helps when object instances are reconciled. | 15 |
| ProcessingCapacity | An indication of the relative processing capacity of the LPAR. Useful in the context of licensing, accounting, charge-back, and planning. | 81 |
| ProcessCapacityUnits | Millions of service units per hour | MSU |
| LPARName | Logical partition name. Example = ES5C. |
Requirements for discovery
- Filtering enabled (which is the default). This class is also sensitive to the ZSeriesComputerSystem filter.
- Discovered only if applicable, which is when the z/OS is running in an LPAR.
