Logging Interval
When LMU 3.0 or 9315/9330 1.0 µ-software is properly installed in the ACS, the HSC
identifies hard fails in LLG1 records and records robotic motion and temporary error
counts in LLG6 records written to SYS1.LOGREC.
An LLG6 record is written to SYS1.LOGREC for each qualified ACS at the same interval
that is defined for writing ACS-specific SMF records. A record is written not less than
once in 24 hours, and always when the HSC is shutting down normally (assuming it has
not been canceled).
An LLG1 record, which may or may not represent a hard fail, is written to
SYS1.LOGREC for most operations requested by the HSC for which the LMU is unable
to complete the HSC request. Operations that are automatically retried by the HSC are
usually not errors, and some other states may be defined that are not logged as errors. See
“LMU Response Codes” on page 611 for information on error and response codes. For
