PR/SM Partition Data Section

This section contains a configured logical partition. There is one for each logical partition. Start of changeThe measurements are on a per logical processor basis when multithreading is disabled and on a per logical core basis when multithreading is enabled for the reporting interval. In the latter case, the terms logical processor and logical CPU refer to a logical core. End of change

Partition has changed from activated to deactivated, or vice versa, during interval
1
Number of logical processors in partition has changed
2
Number of dedicated processors in partition has changed
3
Number of shared processors in partition has changed
4
WLM LPAR management is active for this partition.
5
Wait time field (SMF70WST) is defined.
6
Defined capacity limit has been changed.

10 A SMF70BDN 2 binary Number of logical CPUs assigned to this partition. This count matches the number of subsequent PR/SM™ Partition data sections.

Starting with z900 processors, SMF70BDN has a different meaning if bit 4 of SMF70INB is set. It then contains the maximum logical processors defined as shown at the HMC. Active logical processors have an online time SMF70ONT greater than zero.

12 C SMF70BDS 4 binary The PR/SM logical processor data blocks for all partitions are grouped together in the record. PR/SM logical processor data blocks for a given partition are grouped together. To get to the first logical processor data block associated with this partition, skip over the number of logical processor data blocks specified by this field, starting at the first logical processor data block in the record.
16 10 SMF70BDA 4 binary Accumulated number of active logical processors at a WLM partition. This value is updated at each measurement cycle. It does not cover the logical processors for a non WLM managed partition. (A partition is WLM managed, if bit 4 of SMF70PFG is set.)

To get the average number of logical CPUs, this value has to be divided by the number of Diagnose samples (field SMF70DSA in the CPU control section).

20 14 SMF70SPN 8 EBCDIC LPAR cluster name. For z/OS®, the LPAR cluster name is the sysplex name. For any other logical partition, the LPAR cluster name is the name provided in the HMC definition of this logical partition. Blank, if partition is not a cluster member.
28 1C SMF70STN 8 EBCDIC System name. Blank, if not provided or supported by the operating system in the logical partition.
36 24   4   Reserved.
40 28 SMF70CSF 4 binary Number of megabytes of central storage currently online to this partition.
44 2C   4   Reserved.
48 30 SMF70ESF 4 binary Number of megabytes of expanded storage currently online to this partition.
52 34 SMF70MSU 4 binary Defined capacity limit (in millions of service units).
56 38 SMF70PFL 2 binary Additional partition flags.
Bit
Meaning when set
0
Content of SMF70UPI is valid.
1
Group flag. This partition is member of a capacity group.
2
Polarization flag. This partition is vertically polarized. That is, HiperDispatch mode is active. The SMF70POW fields in the logical processor data section are valid for CPUs of this partition.
3
Initial weight instead of current weight should be used to project usage of the members in the capacity group.
4 -15

58 3A SMF70UPI 1 binary User partition ID. Valid if bit 0 of SMF70PFL is set.

60 3C SMF70GNM 8 EBCDIC Name of the capacity group to which this partition belongs. Valid if bit 1 of SMF70PFL is set.
68 44 SMF70GMU 4 binary Maximum licensing units of a group. The maximum number of processor licensing units for the group of logical partitions of which this partition is a member, and which may be consumed per unit of time, on average. Valid if bit 1 of SMF70PFL is set.
