Cause:

 

 

This was caused by port 443 being blocked in between the two devices. Once customer allowed, all worked as expected.   
   
    Upon running the netstat command we discovered that VxFM isn't listening on tcp port 443.     
   
    vxfm ~]$ curl --insecure --verbose https://xxx.xxx.xx.xxx   
    •About to connect() to xxx.xxx.xx.xxx port 443 (#0)   
    •Trying xxx.xxx.xx.xxx...   
    •Connection timed out   
    •Failed connect to xxx.xxx.xx.xxx:443; Connection timed out   
    •Closing connection 0   
     curl: (7) Failed connect to xxx.xxx.xx.xxx:443; Connection timed out
                                                           

 

 

Resolution:

 

 

   

      VxFM uses port 443 to discover the VxFlex OS gateway.      
      Ensure network devices can communicate with each other over 443 when discovering devices in VxFlex Manager.
