Management Information › Hardware Errors

Hardware Errors

Use information about the hardware errors that occur on your system to diagnose device problems and measure performance. A high error rate indicates the need to change the hardware maintenance procedures that the data center currently uses.

The LOGREC facility records hardware errors in z/OS. When an error occurs (such as hardware failures, selected software failures, and system conditions), z/OS writes a record of the event to the data set named SYS1.LOGREC.

The LOGREC data set is named SYS1.LOGREC, though your data center may have renamed it. z/OS requires LOGREC to be defined in the MASTER JCL. CA Auditor uses the Master Task Input/Output Table (TIOT) to locate the LOGREC data set.
