Creating FC Port Diagnostic Dumps
Diagnostic dump enables you to create and manage a diagnostic dump for a selected
FC port. Dump files contain information, such as firmware version and driver version
for example, that is particularly useful when troubleshooting an adapter.
To start a diagnostic dump:
1. Select a host in the vSphere console tree-view and select the Emulex OneCommand
tab.
2. In the Emulex Device Management tree-view, select the FC port.
3. Select the Diagnostic Dump tab. The Diagnostic Dump information pane appears.

number of files and click Update.
6. Click Start Dump to initiate a diagnostic dump on the selected FC port. Click
Delete Existing Dump Files to remove existing dump files for the selected FC port.
