Chapter 1 Troubleshooting Overview
Using Cisco MDS 9000 Family Tools
Analyzing End-to-End Connectivity
Select the End to End Connectivity option from the Fabric Manager Tools menu to determine
connectivity and routes among devices with the switch fabric. The connectivity tool checks to see that
every pair of end devices in an active zone can talk to each other, using a Ping test and by determining
if they are in the same VSAN. This option uses versions of the ping and traceroute commands modified
for Fibre Channel networks.
The End to End Connectivity Analysis window displays the selected end points with the switch to which
each is attached, and the source and target ports used to connect it.
The output shows all the requests which have failed. The possible descriptions are:
• Ignoring empty zone—No requests are issued for this zone.
• Ignoring zone with single member—No requests are issued for this zone.
• Source/Target are unknown—No nameserver entries exist for the ports or we have not discovered
the port during discovery.
• Both devices are on the same switch—The devices are not redundantly connected.
• No paths exist.
• Only one unique path exists.
• VSAN does not have an active zone set.
• Average time... micro secs—The latency value was more than the threshold supplied.
Analyzing Switch Fabric Configuration
Select the Fabric Configuration option from the Fabric Manager Tools menu to analyze the configuration
of a switch by comparing the current configuration to a specific switch or to a policy file. You can save
a switch configuration to a file and then compare all switches against the configuration in the file.
Figure 1-3 Fabric Configuration Analysis Window
You use a policy file to define the rules to be applied when running the Fabric Checker. When you create
a policy file, the system saves the rules selected for the selected switch.
