General HBA and CNA problems

c. Reseat SFPs in the adapter. Determine whether the installed SFPs are faulty by observing

LED operation by the adapter ports. If all LEDs are flashing amber, the SFP is invalid and

may not be a required Brocade model. You can also verify SFP operation by replacing them

with SFPs in known operating condition. If the problem is resolved after replacement,

original SFP is faulty.

d. Check for conflicts with attached devices. Verify that data speed (1-8 Gbps) and

connection topology (for example, point-to-point) for devices attached to the adapter are

compatible with settings on the adapter port. Although auto may be set, configuring

settings manually on the adapter port and devices may allow connection. Also, note that

the adapter only supports point-to-point connection topology. Refer to the Brocade

Adapters Administrator’s Guide for procedures to configure adapter ports.

NOTE

Observe the LEDs by adapter ports. Illuminated LEDs indicate connection, link activity, and

connection speed negotiated with the attached device. For the meaning of LED operation,

refer to the Brocade Adapters Installation and Reference Manual.

• If the system freezes perform the following tasks:

a. Verify whether the host system firmware supports PCIe specifications listed in the Brocade

Adapters Installation and Reference Manual. If not, download a firmware update to

support the adapter.

b. Verify compatibility by reviewing the Brocade Server Connectivity Compatibility Matrix. To

find this document, log into Brocade Connect on www.brocade.com, then select the

Compatibility Information quick link under Documentation Library.

c. On Windows systems, determine when the system freezes during the boot process. If it

freezes as the driver loads, uninstall and reinstall the driver. If it freezes during hardware

recognition, uninstall both the driver and adapter, then reinstall both.

d. Remove the adapter and reboot the system. If the system boots, reinstall the adapter.

e. Reseat the adapter.

f. Uninstall and reinstall the driver.

g. Try installing the adapter into another host system. If the problem does not occur, the

adapter may not be compatible with the original host system. If the problem occurs in the

new system, replace the adapter.

Action: Refer to “Verifying Fibre Channel and CEE links” on page 32 for more information to isolate

this problem.

Operating system errors (blue screen)

If critical errors display for the host system and the system blue screen appears, refer to the

following descriptions of possible causes and recommended actions to help resolve the problem.

Possible Cause: Adapter driver not loaded.

Action: Refer to “Adapter driver installation verification” on page 34 for methods to verify driver

installation.
