The possible temperature status values are:

• FAIL—Temperature is outside of acceptable range. Damage might occur.
Viewing the system message log
The system message log feature enables messages to be saved across power cycles and reboots.
4/256 SAN Director and DC SAN Backbone Director (short name, DC Director) models maintain an
independent system message log for each of the two CP blades. For these models, you should configure
syslogd to support chronological system message logs. For details, see ”Configuring for syslogd” on
page 298.
For details on error messages, see the Fabric OS Command Reference.
To display the system message log, with no page breaks:
1. Connect to the switch and log in as admin.
2. Enter the errDump command.
To display the system message log one at a time
1. Connect to the switch and log in as admin.
2. Enter the errShow command.
To clear the system message log:
1. Connect to the switch and log in as admin.
2. Enter the errClear command.
All switch and chassis events are removed.
Viewing the port log
The Fabric OS maintains an internal log of all port activity. The port log stores entries for each port as a
circular buffer. Each port has space to store 8000 log entries. When the log is full, the newest log entries
overwrite the oldest log entries. Port logs are not persistent and are lost over power-cycles and reboots. If
the port log is disabled, an error message displays.
NOTE: Port log functionality is completely separate from the system message log. Port logs are typically
used to troubleshoot device connections.
To view the port log:
1. Connect to the switch and log in as admin.
