  • Page 45: Error Message Format

    Fabric OS Commands The syslogd is a process that runs on UNIX or Linux systems that reads and logs messages to the system console, log files, other machines and users as specified by its configuration file. Refer to the manual pages and related documentation for your particular UNIX host system for more information on the syslogd process and its capabilities.

  • Page 46: Message Classification

    Fabric OS Commands Message Classification 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 switch supports 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.
  • Page 47 Fabric OS Commands To disable sending of error log messages to a previously enabled remote syslogd host do the following: 1. Login to the switch as Admin user. 2. At the command line enter the syslogdipremove command as follows: switch:admin>syslogdipremove “IP address of the remote syslogd host”...

  • Page 48: Updating The Core Switch Pid Format

    Updating the Core Switch PID Format Command Summary syslogdipadd—Add the IP address of the remote syslogd host to the switch. syslogdipremove—Remove the IP address of the remote syslogd daemon. syslogdipshow—Show the list of configured syslogd IP addresses. errshow—Display messages from the error log on the switch. Updating the Core Switch PID Format Updating the Core Switch PID Format is necessary when upgrading an existing SAN to support larger port-count switches.
  • Page 49 Updating the Core Switch PID Format Note: All switches running any version of Fabric OS 4.x are shipped with the Core Switch PID Format enabled, so it is not necessary to perform the PID format change on these switches. The actual process of changing the PID format is quite simple. Telnet into each switch in the fabric, and disable the switch using the switchDisable command.
