No Adapters Reported Though Bcu Adapter --List Command; Port Link Is Not Active - Brocade Communications Systems CNA 1010 Troubleshooting Manual

No adapters reported though BCU adapter --list command

If the adapter does not display when the BCU adapter --list command is initiated, refer to the
following descriptions of possible causes and recommended actions to help resolve the problem.
1. Possible Cause: Adapter is not reported under server's PCI subsystem.
2. Possible Cause: Adapter driver is not loaded.

Port link is not active

The link between the adapter and switch port does not appear to be active because of adapter LED
operation (stand-up adapters only), lack of data over the link, or the BCU port --query or port --list
command shows that the link state is down. Refer to
information.
Refer to the following descriptions of possible causes and recommended actions or fixes for the
problems:
1. Possible Cause: SFP or cable problems (stand-up adapters).
2. Possible Cause: Switch port is disabled or switch is disabled.
3. Possible Cause: Adapter port is disabled.
4. Possible Cause: Adapter's port speed or topology mismatch with the switch port (HBAs only).

Action: Verify if the adapter is visible as a PCI device by executing your host's operating system
command to list PCI devices in the system. For details on this command, refer to the "List PCI

Action: Ensure that the SFPs and cables are connected properly on both adapter and switch
sides. Check for any cable damage.
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.
Action: Verify port state using the HCM Port Properties dialog box or BCU port --list command.
Use BCU port --enable command to enable the port.
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
