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.
