9.1.1 Relationship to VCC SMF Record Production


VCC provides the raw input data to the Space Analyzer in SMF
format.  The records can be written to separate data sets for
direct input into the daily update steps (DAY090 and DAY095),
or they can be written to the standard system SMF data sets.
See the CA MICS Space Collector Guide for more information on
the creation and format of the records, as well as the
options available for tailoring the collection process.

Two different SMF record types are produced by VCC for input
to the Space Analyzer.  The defaults are SMF record type 198
for VCA and type 197 for HSM (and HSB).

The type 198 record containing information for building the
VCA Information Area is segmented in such a way that
different types of data can be represented by one record.
The different segment types contain overall configuration
information, non-VSAM data set information, VSAM data set
information, and VTOC/volume information, which is then used
to construct the various CA MICS files.

The type 197 record is divided into different subtypes, such
that each subtype addresses a different DFHSM resource.
There are five different subtype records, identified as:

    - subtype M (a migrated data set)
    - subtype B (a backup version)
    - subtype C (a DASD volume statistics record)
    - subtype T (a record of DFHSM-managed tape volumes)
    - subtype Z (a VCC-generated inventory trailer record)

As with the type 198 record, various CA MICS files are
constructed from the information contained in the different
subtypes.
