Diagnostics

fcdiag --linkbeacon <portid> {on | off} [<duration>]

where:

port_id ID of the port for which you want to run a link beacon test.

on | off Toggle on or off. If turned on, you can specify duration.

duration Length of time between blinks.

Enabling beaconing through HCM

Enable link and port beaconing using the following steps.

1. Launch the HCM.

2. Select the base adapter port from the device tree window.

3. Click Configure > Beacon.

4. Click the Beacon Link check box, the Beacon Port check box, or both.

Internal and external loopback tests

Use the BCU or the HCM to perform a loopback test for a specific port. Loopback tests require that

you disable the port. The following loopback tests are available:

• Internal

Random data is sent to the adapter port, then returned without transmitting through the port.

The returned data is validated to determine port operation. Errors may indicate a failed port.

• External

For this test, a loopback connector is required for the port. Random data is sent to the adapter

port. The data transmits from the port and then returns. The returned data is validated to

determine port operation. Errors may indicate a failed port.

Performing loopback tests through BCU

Use the diag --loopback BCU command test to verify port function through a loopback test.

bcu diag --loopback <port_id> [-t <loopback_type>][<duration>][-s <speed>]

[-c <frame_count>] [-p <pattern>]

where:

port_id ID of the port for which you want to run the test.

loopback type Type of loopback test. Possible values are internal, external, and serdes.

speed HBAs only. For 8 Gbps adapter, this is 2, 4, or 8. For 4 Gbps adapter, this is 1,

2 or 4.

duration Length of time between blinks.

frame count Integer from 0 to 4,294,967,295. Default is 8192.

-p pattern Hex number. Default value is A5A5A5A5.
