EXTDATA Record Type - S42I

The MRXT42I and MZXT42I record definitions define the EXTDATA records created by CA JARS from SMF record 42, subtype 6, Dataset Level I/O Statistics for DASD volumes at interval expiration. There is one SMF record 42, subtype 6, for each type 30 interval record.

For a complete description of each SMF data field listed below, refer to the z/OS MVS System Management Facilities (SMF) Guide, SA22-7630. The chapter entitled "Record Type 42 (2A) DFSMS Statistics and Configuration" gives a detailed description of each field.

Additional information on the contents of RMF Type 42 records can be found by assembling the RMF mapping macro SYS1.MACLIB(IFASMFR), as in this example:

RECMAP   DSECT
         IFASMFR (42)
         END

All of the fields listed below are found in the macro IFASMFR and its subordinate macros.

Note: Although record types S42D and S42I appear similar, S42D records are produced at event boundaries, and S42I records depict state at the end of a DFSMS interval.
