syslogd configuration
The syslog configuration provides the syslogd with instructions on how to handle
different messages. Figure 31 and Figure 32 are example entries in a syslog
configuration file (
/etc/syslog.conf
), of how to store switch error messages stored
in different files. Refer to the syslog manual pages on your UNIX system for the full
documentation of the syslog configuration file.
Figure 31 shows the entry in
/etc/syslog.conf
that causes all messages from the
silkworm
of UNIX priority warning or higher (switch severity
LOG_WARNING
or higher)
to be stored in the
file/var/adm/silkworm
file.
Figure 32 shows the entries in
/etc/syslog.conf
that cause the messages from the
silkworm
of UNIX priority alert (switch severity
LOG_CRITICAL
) to be stored in the
file/var/adm/alert
file, and all other messages from the switch to be stored in the
/var/adm/silkworm
file.
The
local7
prefix identifies the message from a switch. Note that usually a file must
exist and have the proper permission in order for the syslogd to write to it.
Power-on self-test (POST)
When the switch is started, a series of commands are executed to test the switch.
This procedure is called the POST.
The fabric OS POST includes the following tests:
ramTest
- Bit write and read test of SDRAMS in the switch.
Enable and verify syslogd support:
