General HBA and CNA problems

Port link is not active

The link between the adapter and switch port does not appear to be active because of adapter LED

operation, lack of data over the link, or BCU port --query or port --list command shows that the link

state is down. Refer to “Displaying the port list” on page 73 for more information.

Refer to the following descriptions of possible causes and recommended actions or fixes for the

problem.

1. Possible Cause: SFP or cable problems.

Action: Ensure that the SFPs and cables are connected properly on both adapter and switch

sides. Check for any cable damage.

2. Possible Cause: Switch port is disabled or switch is disabled.

Action: Execute either the Fabric OS switchShow or portShow commands on the attached

switch to ensure that the switch or individual port is not disabled or offline. Use appropriate

switch commands to enable the port.

3. Possible Cause: Adapter port is disabled. Verify port state using the HCM Port Properties dialog

box or BCU port --list command. Use BCU port --enable command to enable the port.

4. Possible Cause: Adapter’s port speed or topology mismatch with the switch port (HBA only).

Action: Check the port topology setting on the switch using the Fabric OS portCfgShow

command to ensure that Locked L_Port is OFF. Use the portCfgLport command to change the

setting to OFF if required.

Action: Check the switch port speed using the Fabric OS portCfgShow command to verify that

speed is either AUTO or matches the speed of the attached adapter port (for example, the

speed setting for both ports is 4 Gbps).

Action: Check port speed on the adapter with the BCU port --list or port --query commands to

display the current and configured speed. Refer to “Displaying port speed” on page 73 and

“Performing a port query” on page 73 for details on using these commands.

5. Possible Cause: Non-Brocade branded SFP installed. If non-Brocade branded SFPs are

inserted on the adapter or switch, the port link will not come up.

Action: On the switch, execute the Fabric OS switchShow command to verify that “Mod_Inv”

(invalid module) does not display for the port state.

Action: On the adapter, execute the port --list or port --query BCU commands to verify the

adapter. Refer to “Displaying the port list” on page 73 and “Performing a port query” on

page 73. If an unsupported SFP is detected, the Sfp field displays 'us' (unsupported SFP) for

port --list and the Media field displays “Unsupported SFP” for port --query.

For additional actions and fixes for the port link not coming up, refer to “Verifying Fibre Channel

and CEE links” on page 32.

6. Possible Cause: Firmware failure. In most cases this causes a heartbeat failure, and if

auto-recovery is enabled, the driver recovers. No corrective action is needed.

Action: If link does not recover and BCU port --list command shows fcoe and eth state is link

down, download the latest driver package from the Brocade adapter website

(www.brocade.com/hba or www.brocade.com/cna). Remove and reinstall the driver package

using instructions in the “Installation” chapter of the Brocade Adapters Installation and

Reference Manual.
