RMF LPAR Level Analysis
Before tracking utilization at the individual logical partition level, the most important item that determines the strategy used in measuring CPU time used is the logical processor configuration.
rm
Because LPAR measurements may be distributed across several processor pools' sets of

s, you need to know the types of resources an LPAR may consume standard CP, special purpose (ICF, IFL, zAAP, zIIP), or both.The way an LPAR is configured, with its PR/SM mode of operation, defines its type, which can be either general purpose or special purpose. The following table provides you with all possible LPAR configurations, and the last column (LPAR Type) helps you find information in the rest of this section:
