Suggestion: The error message indicates that the wrong firmware image has been programmed
on the adapter card.
See
Section 2,“Downloading Mellanox WinOF Driver,” on page 17.
Issue 5. The Ethernet driver fails to start. A yellow sign appears near the "Mellanox ConnectX
10Gb Ethernet Adapter" in the Device Manager display.
Suggestion: This can happen due to a hardware error. Try to disable and re-enable "Mellanox
ConnectX Adapter" from the Device Manager display.
Issue 6. No connectivity to a Fault Tolerance bundle while using network capture tools (e.g.,
Wireshark).
Suggestion: This can happen if the network capture tool captures the network traffic of the
non-active adapter in the bundle. This is not allowed since the tool sets the packet filter to "pro-
miscuous", thus causing traffic to be transferred on multiple interfaces. Close the network cap-
ture tool on the physical adapter card, and set it on the LBFO interface instead.
Issue 7. No Ethernet connectivity on 10Gb adapters after activating Performance Tuning (part
of the installation).
Suggestion: This can happen due to adding a TcpWindowSize registry value. To resolve this
issue, remove the value key under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControl-
Set\Services\Tcpip\Parameters\TcpWindowSize or set its value to 0xFFFF.
Issue 8. Packets are being lost.
Suggestion: This may occur if the port MTU has been set to a value higher than the maximum
MTU supported by the switch.
Issue 9. Issue(s) not listed above.
