Resetting Bad Ports
If any port fails during a diagnostic test, it is marked
BAD
in the status display.
To retest a port which has been marked BAD, clear the port and set to OK using the
diagClearError command. This command clears the port status only and does not clear the logs or
change the port’s condition. The diagClearError command should only be used during diagnostic
procedures to reset a bad port for retest.
Post Test Commands
When the switch is booted a series of commands are executed to test the hardware of the switch.
This procedure is called the POST (power on self test).
The Fabric OS POST includes the following tests:
For more information about these tests, refer to the individual command descriptions in Chapter 1,
Telnet Commands.
Note:
The cold boot (power reset) runs the long ramTest while the warm boot (software reset)
runs the short ramTest.
