6.5.2 Sample Data Elements in the RMF LCU Summarized File

The LCU file is created from the HARDVA, SCPIOC, and SCPLCA
files.  Since some of the data elements are computed from RMF
sample counts, and the sample counts from the source files
vary, two separate sample count data elements are stored in
the LCU file:

    LCURSMPD is the RMF sample count from the HARDVA file
    LCURSMPL is the RMF sample count from the SCPLCA file

The CA MICS Summarization Facility uses the appropriate data
elements when resummarizing LCU data elements.  However, if
calculations are performed manually, it is important to know
which total to use.

The following data elements are affected by or related to RMF
sampling.  Read the data dictionary entries for these
elements before attempting to perform calculations with them.

    From the HARDVA file:

       LCUALC   - Device Allocated
       LCUAVDSO - Average Data Sets Open on Device
       LCUAVIOS - Average Device IOS Queue Time
       LCUAVQUE - Average Requests Queued
       LCUAVRES - Average Device Response Time
       LCUDSO   - Data Sets Open on Device
       LCUICT   - Number of Invalid Samples
       LCUMPT   - Mount Pending Condition
       LCUNRD   - Device Not Ready
       LCUPCALC - Percent Device Allocated
       LCUPCMTP - Percent Mount Pending Condition
       LCUPCNRD - Percent Device Not Ready
       LCUPCRSV - Percent Device Reserved
       LCUPCUTL - Percent Device Utilized
       LCURSMPD - RMF Sample Count (from DVA)
      LCURSV   - Device Reserved
       LCUUTL   - Device Reserved and Idle

    From the SCPLCA file:
