Chapter 1. IBM Flex System FC3171 8 Gb SAN Switch - QLogic

To run a diagnostics test on a port, do the following:
1. In the faceplate display, select a port, open the Port menu and select Port
Diagnostics.
2. Choose one of the following:
• Select Online Port Diagnostics to open the Port Diagnostics dialog. Select the
port to test in the Select Port drop-down list. The test type is Online by
default.
• Select Offline Port Diagnostics to open the Port Diagnostics dialog (this
option will disrupt traffic). Select the port number and Internal or External
test type in the drop-down list.
3. Enter a frame size (default is 256).
4. Enable or disable the Terminate Test Upon Error option.
5. Select a Loop Count option. The Loop Forever option runs the test until you click
the Stop Test button. The Loop Count option runs the test a specific number of
times.
6. Select a Test Pattern option. Accept the default test pattern, or select the User
Defined option and enter a value.
7. Click the Start Test button to begin the test. Observe the results in the Test
Results area.
Notes:
If the Test Status field in the Test Results area indicates Failed, note the Test Fault
Code displayed in the Port Information data window and contact Tech Support.
Mapping ports
When the switch is in transparent mode, the Map Ports dialog enables you to
configure data traffic routes from server bay ports to one or more uplink ports.
Server bay ports are called TH_Ports (transparent host). An uplink port that
attaches to an external server must be configured as a TH_Port. At least one uplink
port must connect to a fabric switch that supports NPIV. An uplink port that
connects to a fabric switch is a TF_Port (transparent fabric). By default, the six
uplink (external) ports are TF_Ports.
You can assign a TH_Port to multiple TF_Ports using the Map Port dialog box. For
redundancy, a backup port mapping can also be specified. Leaving a TH_Port
unmapped has the same effect as unplugging a Fibre Channel cable. You can map
multiple primary and backup ports for any TH_Port. A port designated as primary
will be the first path chosen. If there are multiple primary ports, the TH_Ports are
distributed (using an algorithm) across the TF_Ports. Ports designated as backup
ports become active only when all primary ports fail.
