I don't have a UCS system at hand, therefore I propose you the indirect, but very powerful method:
In the PowerTool session window, run “ConvertTo-UcsCmdlet”. This command will monitor the most recent GUI logfile for configuration changes (the actual path/filename is indicated in the output).
Arrange the desktop windows so you have access to the UCSM GUI and the PowerTool session.
Got to UCSM and excute the command(s) to display the vnic x of your SP abc...
After Clicking “OK”, you will see the “ConvertTo-UcsCmdlet” output for this action(s).
Note: The first conversion may take up to 30s, as metadata is compiled (one-time only)
