RMFSTO – CPC LPAR Storage Allocation

Overview

The RMFSTO query generates a chart for each Central Processing Complex (CPC). The chart shows the central and expanded storage for the CPC, and how that storage is assigned to each LPAR.

The example shows the chart generated for an IBM z/10 2097-712 CPC. The two vertical bars for the leftmost LPAR, named ##CPC##, show the total amount of central and expanded storage, in megabytes, in the CPC. The distribution of this storage is shown for the active LPARs to the right. Notice that all LPARs are assigned some amount of central storage, but not all LPARs have expanded storage.

Uses

This query provides a useful view of CPC storage distribution at a glance. Analysis of central and expanded storage workload constraint may require better distribution of the available resource.

Data Extracts

CPC LPAR Storage Allocation

Left Y-axis

LPCCSF - Central Storage Megabytes Assigned

LPCESF – Expanded Storage Megabytes Assigned

X-axis

PRSMLPNM – Logical Partition Name

Note: The leftmost LPAR, ‘##CPC##’ storage values are the sum of all storage allocated to the active LPARs.

Query Defaults

• HARLPC DAYS timespan file: Cycle 01
• User code selects yesterday’s data (IF DATEPART(ENDTS) EQ TODAY()-1 ;
• User code overwrites LPAR=’PHYSICAL’ to represent values for CPC level LPAR: ‘##CPC##’
• Derivations:

  DATE

  DATEPART(ENDTS)
  

  CPCID

  TRIM(LPCMOD)||'-'||TRIM(CPCMODID)||'-Serial: '||SUBSTR(CPCSEQNB,12,5);
  

Modifications

The following modifications can be made to the RMFSTO query:

• You can add filter statements to select only a single CPC, or set of CPCs using some of the identifying data elements shown in the CPCID derivation.
