Small Form-Factor Pluggable (SFP) Issues

Items to check for common SFP-related symptoms are listed below.

The switch is not receiving a valid Fibre Channel signal from the

 

end node (HBA or disk array) or is receiving LIP(F8).

 

1) Ensure that the device is powered on and operating properly.

 

2) Unplug the fiber cable from the node and verify that an

 

optical signal is present on the cable receiver lead.

available, verify the device is transmitting a signal.

 

 

If there is no signal present, the device may require rebooting,

 

device drivers may need to be reinstalled, or the HBA or disk

 

controller hardware may require servicing.

 

If a signal is present on both the cable lead and the end node, the

 

HBA or disk controller may require service.

 

 

 

The switch is receiving a valid Fibre Channel signal from the end

 

device (HBA or disk), but no upper level protocols are active.

 

1) Verify that the proper HBA device drivers are loaded for the

 

appropriate operating system and that the host has been

 

configured to recognize attached disk devices.

 

2) Check the Switch Op LED. If the Switch Op LED is on, the

 

devices have completed initialization. If the Switch Op LED is

3) Improper initialization could result from a defective or

 

 

inoperative adapter card or device. Run adapter diagnostics with

 

a loopback connector to see if the adapter is working properly.

 

4) Unplug the fiber cable from the end node and verify that an

 

optical signal is present on the cable receiver lead. If no signal is

 

present, the receiver lead of the cable may be bad and the device

 

may be streaming LIP(F8). Ensure that all cascaded ports are

 

correctly configured.
