Diagnostics and Status Switch 2/64 uses the kernel logging facility. The word "kernel" is the name of the syslogd facility used by the Core Switch 2/64 or SAN Switch 2/32 to send error log messages to the remote host. The rest of the message is similar to the error log message output from the errshow command line interface on the switch. The fields that are specific to the switch error log message are: ■ ID of the task that generated the error (in the example this is 0x299) ■ Name of the task that generated the error (in the example this is (fabos)) ■ Switch instance number (in the example this is Switch 0) ■ Message severity level in word (in the example this is Info) ■ The error message identifier consisting of the module name (in the example this is HAMKERNEL) and the message name (in the example this is IP_UP) ■ Numeric value of the message severity level defined by the switch (in the example this is 4) ■ A descriptive text string (in the example, this is Heartbeat up from Standby CP) Message Classification The syslogd messages are classified according to facility and priority (severity code). This enables a system administrator to take different actions depending on the error. The Core Switch 2/64 and SAN Switch 2/32 support 6 message severity levels for error log messages. The following table provides a mapping between severity levels used by the switch and the syslogd severity levels supported by the UNIX system. Core Switch 2/64 and SAN Switch 2/32 Message severity Levels/Numerical Value Panic (0) Critical (1) Error (2) Warning (3) Info (4) Debug (5) UNIX syslogd message severity levels/Numerical Value Emergency (LOG_EMERG) (0) Alert (LOG_ALERT) (1) Error (LOG_ERR) (3) Warning (LOG_WARNING) (4) Info (LOG_INFO) (6) Debug (LOG_DEBUG) (7) 172 Fabric OS Procedures Version 3.1.x/4.1.x User Guide
