This topic describes the logging and tracing capabilities available on SAN File System AIX clients.
Use the stfsdebug command and the syslog facility to enable tracing and logging on the SAN File System AIX client.
The SAN File System client generates both log and trace messages, which are routed through the syslog facility on the AIX operating system. The syslog facility captures log and trace output from the kernel as well as other operating system services.
kern.debug /var/adm/ras/messages
You can also redirect the kern.debug to /var/spool/mqueue/syslog instead of /var/adm/ras/messages by specifying that directory instead. Create the /var/spool/mqueue/syslog file first by using the touch command.
kill -hup syslogd_PIDRefer to either AIX 5L Version 5.1 Commands Reference, Volume 5 or AIX 5L Version 5.2 Commands Reference, Volume 5, s-u for more information about the syslogd daemon.
kern.debug /dev/console
kill -hup syslogd_PIDRefer to either AIX 5L Version 5.1 Commands Reference, Volume 5 or AIX 5L Version 5.2 Commands Reference, Volume 5, s-u for more information about the syslogd daemon.
When you specify kern.debug as shown in the previous examples, all levels of kernel output are routed because debug is the lowest priority level of kernel output. You could specify a different level of output, such as kern.info to show just informational messages.
The following example messages show the format of log messages:
Apr 21 07:43:50 aixclient1 unix: STFS: disk configuration process created with PID = 13348 Apr 21 07:43:50 aixclient1 unix: STFS: cleaner process created with PID 12028 Apr 21 07:43:50 aixclient1 unix: STFS: CSM process created with PID 10860
The following example messages show the format of trace messages:
