6.8.5.1.1 HARIPU/HARCPU Relationship
All the information stored in the HARIPU file is summarized
in the HARCPU file. The only difference is data granularity.
HARIPU contains logical processors' detailed information,
while HARCPU contains LPAR level totals. In order to fully
understand the structural differences between these two
files, it is important to remember that, currently, only one
type of logical partition can create SMF type 70 records, and
hence, populate the HARIPU/HARCPU files: z/OS images.
A z/OS LPAR may be configured either with standard CP
processors only or a mix of standard CP and specialized
processors (zAAPs,zIIPs). Specialized processors' activity
must be kept separate from standard CP processors' activity.
Think of the HARIPU/HARCPU files' organization in terms of
tables with rows and columns. The HARIPU file contains one
row per logical processor configured within a logical
partition. In each row, one column is used to identify
whether the remaining metrics are attributable to a standard
CP, zAAP, or zIIP processor. The same information is
represented in the HARCPU file by a single row for each
logical partition with three sets of summarized data columns:
one for standard CP processors' metrics, one for zAAP
metrics, and one for zIIP metrics.
Example
-------
Let's assume the following PR/SM configuration:
o SYS1 is z/OS LPAR configured with two standard CP
processors, one zAAP, and one zIIP.
o SYS2 is z/OS LPAR configured with two standard CP
processors.

For SYS1, busy times for processors 0 and 1 have been
consolidated in the overall busy time for all standard CP
processors (same for SYS2), busy time for the zAAP (processor
2) has been summarized in the SYS1 overall busy time for all
zAAPs, and busy time for the zIIP (processor 3) has been
summarized in the SYS1 overall busy time for all zIIPs.
