Figure 6–6: Performing diagnostics on ports
To run these tests, make sure that the administrator for any device attached to the ports
quiesces Fibre Channel frame traffic through the product and sets the attached devices
offline. A message will display in the status area to notify you that device applications
should be terminated before starting diagnostics. However, since these tests disrupt
port operation, make sure that there are no active nodes connected to the port(s) before
starting a test. A loopback plug, furnished with the product, is required for the external
loopback test.
NOTE: To identify port numbers on cards that you want to test, drag the mouse cursor across
the cards in the Unit view. A label displays with the port number.
1. Enter a port number in the Targeted Port Number field.
2. Click the arrow on the Diagnostic Test drop-down list to display the available
tests (Internal Loopback and External Loopback), then click a test to choose it.
