Resetting Bad Ports; Post Test Commands - HP StorageWorks 8B - FC Entry Switch Reference Manual

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:
