Cisco DCNM-SAN Troubleshooting Tools

</h1>
<a name="wp371004"> </a><p class="pBody">
Cisco DCNM-SAN has several troubleshooting tools available from the toolbar or Tools menu

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp371009"> </a><li class="pSmartList1"><b style="font-weight: normal" class="cBold">Zone Merge Analysis</b>&#8212;The zone merge analysis tool (available from the Zone menu) enables you 
to determine if zones will merge successfully when two Cisco MDS switches are interconnected. If 
the interconnected switch ports allow VSANs with identical names or contain zones with identical 
names, then Cisco DCNM-SAN verifies that the zones contain identical members. The merge 
analysis tool can be run before attempting a merge or after fabrics are interconnected to determine 
zone merge failure causes.
</li>
<a name="wp345225"> </a><li class="pSmartList1"><b style="font-weight: normal" class="cBold">End-to-End Connectivity</b>&#8212;Cisco DCNM-SAN’s end-to-end connectivity analysis tool uses FC Ping 
to verify interconnections between Cisco MDS switches and end-device (HBAs and storage devices) 
in a particular VSAN. In addition to basic connectivity, Cisco DCNM-SAN can optionally verify the 
following:
</li>
<div class="pSmartList2"><ul class="pSmartList2">
<a name="wp345226"> </a><li class="pSmartList2">Paths are redundant.</li>
<a name="wp345227"> </a><li class="pSmartList2">Zones contain at least two members.</li>
</ul></div>
</ul></div>
<a name="wp345228"> </a><p class="pBody">
End devices are connected to a manageable switch (have a currently active in-band or out-of-band 
management path.)

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp345229"> </a><li class="pSmartList1"><b style="font-weight: normal" class="cBold">Switch Health Analysis</b>&#8212;You can run an in-depth switch health analysis with Cisco DCNM-SAN. 
It verifies the status of all critical Cisco MDS switches, modules, ports, and Fibre Channel services. 
Over 40 conditions are checked. This tool provides a very fast, simple, and thorough way to assess 
Cisco MDS switch health.
</li>
<a name="wp345230"> </a><li class="pSmartList1"><b style="font-weight: normal" class="cBold">Fabric Configuration Analysis</b>&#8212;Cisco DCNM-SAN includes a fabric configuration analysis tool. It 
compares the configurations of all Cisco MDS switches in a fabric to a reference switch or a policy 
file. You can define what functions to check and what type of checks to perform. The analysis can 
look for mismatched values, and missing or extra values. If all configuration checking is performed 
for all functions, over 200 checks are performed for each Cisco MDS switch.
</li>
</ul></div>
<a name="wp345231"> </a><p class="pBody">
After the analysis is run, the results are displayed with details about the issues that were discovered. You 
can automatically resolve configuration differences by selecting them and clicking the <span style="font-weight: bold">Resolve</span> button. 
Cisco DCNM-SAN automatically changes the configuration to match the reference switch or policy file.
