General adapter problems
2
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.
