The error logging facility records hardware and software failures in the error log for information purposes or for fault detection and corrective action.
Refer to the following to use the error logging facility:
In AIX Version 4, some of the error log commands are delivered in an optionally installable package called bos.sysmgt.serv_aid. The base system (bos.rte) includes the services for logging errors to the error log file. This includes the errlog subroutines, the errsave and errlast kernel service, the error device driver (/dev/error), the error daemon, and the errstop command. The commands required for licensed program installation (errinstall and errupdate) are also included in bos.rte. See "Software Service Aids Package" for more information. Also, for information on transferring your system's error log file to a system that has the Software Service Aids package installed, see "Transferring Your Error Log to Another System".
The following diagram illustrates the error logging process:
