AIX 5L Problem Determination - IBM Redbooks

To change the current log file, the errdemon command is used as follows:
# /usr/lib/errdemon -i /var/adm/ras/myerrlog
To change the error log file size, the errdemon command is used as follows:
# /usr/lib/errdemon -s 47798
To change the error log buffer size, the errdemon command is used as follows:
# /usr/lib/errdemon -B 16384
0315-175 The error log memory buffer size you supplied will be rounded up
to a multiple of 4096 bytes.
The new status can be checked using the errdemon command as follows:
# /usr/lib/errdemon -l
Error Log Attributes
--------------------------------------------
Log File /var/adm/ras/myerrlog
Log Size 47798 bytes
Memory Buffer Size 16384 bytes
The errdemon command without flags will start the error daemon if it is not
running as follows:
# /usr/lib/errdemon
If the error daemon is running, an error will be reported as follows:
# /usr/lib/errdemon
0315-100 The error log device driver, /dev/error, is already open.
The error demon may already be active.
6.3 The errpt command
The errpt command generates an error report from entries in an error log. It
includes flags for selecting errors that match specific criteria. By using the default
condition, you can display error log entries in the reverse order in which they
occurred and were recorded. By using the - c (concurrent) flag, you can display
errors as they occur. If the -i flag is not used with the errpt command, the error
log file processed by errpt is the one specified in the error log configuration
database (by default /var/adm/ras/errlog).
The default summary report contains one line of data for each error. You can use
flags to generate reports with different formats.
