6.2 Record Descriptions


The records contained in ERDS can be of two types:
statistical data and environmental data.  Records have a
maximum length of about 1900 bytes.  There is a 24 byte
standard header.  The records do not contain the SYSID of the
system.  The CPU serial number is however available.  This
provides a way to correlate a SYSID based on CPU serial
number.  This method is discussed in Chapter 7 under Unit
Level Parameters.

The following figures list the various record types that the
CA MICS System Reliability Analyzer reads. The record types
are arranged by operating system.
