Brocade Adapters Troubleshooting Guide 19

General adapter problems

1. Action: Reassess the hardware configuration and distribute the adapters so no more than four

10Gbps Ethernet ports are used in a single system (maximum supported by VMware). This

VMware limitation applies to Brocade CNA ports and Fabric Adapter ports configured in CNA

mode.

2. Action: If there are a large number of Brocade HBA ports or Fabric Adapter ports configured in

HBA mode in the system, try disabling MSI-X mode for Brocade ports using the following

commands.

a. Enter the following command to display current driver configuration settings, including

default options.

esxcfg-module -g bfa

b. Append "msix_disable_cb=1" to the default options displayed by the preceding command:

esxcfg-module -s "<default_options> msix_disable_cb=1" bfa

NOTE

Disabling MSI-X mode can reduce performance so any performance critical tasks should be

done with a smaller number of adapters in the system, in order to utilize the MSI-X mode.

Driver installation fails on ESX systems

Driver(s) are not installing on VMware ESX system. If installing through HCM, the following error

message may display when updating drivers.

Uploading of the driver file is failed. Reason - Maintenance mode is not enabled

or could not be determined.

Possible Cause: ESX systems must be in maintenance mode to install or update drivers.

Action: Place system in maintenance mode, then reinstall driver plackage(s).

Errors when using GUI-based software installer

Errors occur when launching the GUI-based Brocade Adapter Software Installer, such as

InvocationTargetException errors

Possible Cause: Your system may not be able to run a GUI-based application.

Action: Use the Software Installer commands detailed in the Brocade Adapters Installation and

Reference Manual.

Errors when installing brocade_driver_linux_<versions>.tar.gz package

If errors occur when installing the no architecture (noarch) brocade_driver_linux_<versions>.tar.gz

driver package, refer to the following descriptions of possible causes and recommended actions to

help resolve the problem.

Possible Cause: Appropriate distribution kernel development packages are not installed on your

host system for the currently running kernel.
