Troubleshooting with Host tools
You can troubleshoot the CNA with following host-based tools:
•
•
•
CNA not recognized by Host OS
Although the CNA is installed on the host, the Converged Network Adapter (CNA) is not recognized.
Possible Cause
The host operating system may not have the appropriate drivers to support the installed Converged
Network Adapter model.
Solution
1) Obtain the following information:
Step 1
a.
b.
Reference the appropriate vendor support page for the CNA model and host OS.
Step 2
Determine if an existing driver is already installed on the host OS.
Step 3
Ensure that the latest driver is installed from the CNA vendor support page or the host OS support page.

A unique dedicated VLAN must be configured at every converged access switch and every blade
switch to carry traffic for each virtual fabric (VSAN) in the SAN (for example, VLAN 1002 for
VSAN 1, VLAN 1002 for VSAN 2, and so on). If MSTP is enabled, a separate MST instance must
be used for FCoE VLANs.
Unified Fabric (UF) links must be configured as trunk ports. FCoE VLAN must not be configured
as a native VLAN. All FCoE VLANs must be configured as members of the UF links. This allows
it to be extendible for VF_Port trunking and VSAN management for the VFCs.
UF links between the CNAs and the blade switches must be configured as spanning tree edge ports.
A blade switch must connect to exactly one converged access switch, preferably over an Ethernet
port channel to avoid disruption due to STP reconvergence on events such as provisioning of new
links or blade switches.
Emulex
Emulex provides the OneCommand GUI tool to manage Emulex CNAs. The CEE tab of this
–
tool displays details about DCB configurations and FIP settings within the FC interface.
Qlogic
Qlogic provides the SanSurfer tool. The Data Center Bridging tab of this tool displays the DCB
–
configuration learned from the switch alone with TLV exchange data. The DCE Statistics tab of
this tool displays the ethernet statistics.
Microsoft Windows
– Microsoft Windows provides tools to view the configuration and registers for many CNA vendor
products.
