Resolution:

 

 

   

      * rebooted VxRail Manager given hat the error shows Cannot allocate memory. After the reboot we could start the upgrade.   

   

      * completed upgrade from 3.5 to 4.0.100 successfully   

                                                             

 

 

Notes:

 

 

   

      VxRail Manager is not connected to the internet, internet upgrade is ruled out     
      lcm.log file is missing becuase the upgrade has not even started.
