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 1Gb/100Mb 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. System reboots on an I/OAT capable system on Windows Server 2008.
Suggestion: This may occur if you have an Intel I/OAT capable system with Direct Cache
Access enabled, and 9K jumbo frames enabled. To resolve this issue, disable 9K jumbo frames.
Issue 9. 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 10. Issue(s) not listed above.
Suggestion: The MLNX_EN for Windows driver records events in the system log of the Win-
dows event system. Using the event log you'll be able to identify, diagnose, and predict sources
of system problems.
To see the log of events, open System Event Viewer as follows:
1. Right click on My Computer, click Manage, and then click Event Viewer.
OR
1. Click start-->Run and enter "eventvwr.exe".
2. In Event Viewer, select the system log.
The following events are recorded:
• Mellanox ConnectX EN 10Gbit Ethernet Adapter <X> has been successfully initialized and enabled.
• Failed to initialize Mellanox ConnectX EN 10Gbit Ethernet Adapter.
• Mellanox ConnectX EN 10Gbit Ethernet Adapter <X> has been successfully initialized and enabled.
The port's network address is <MAC Address>
• The Mellanox ConnectX EN 10Gbit Ethernet was reset.
• Failed to reset the Mellanox ConnectX EN 10Gbit Ethernet NIC. Try disabling then re-enabling the
"Mellanox Ethernet Bus Driver" device via the Windows device manager.
• Mellanox ConnectX EN 10Gbit Ethernet Adapter <X> has been successfully stopped.
• Failed to initialize the Mellanox ConnectX EN 10Gbit Ethernet Adapter <X> because it uses old
firmware version (<old firmware version>). You need to burn firmware version <new firmware ver-
sion> or higher, and to restart your computer.
