Synchronizing Your Gateway VM Time

For a gateway deployed on VMware ESXi, setting the hypervisor host time and synchronizing the VM time to the host is sufficient to avoid time drift. For more information, see Synchronizing VM Time with Host Time. For a gateway deployed on Microsoft Hyper-V or Linux KVM, you should periodically check your VM's time using the procedure described following.

To view and synchronize the time of a hypervisor gateway VM to a Network Time Protocol (NTP) server
  1. Log in to your gateway's local console:

  2. On the Storage Gateway Configuration main menu, enter 4 for System Time Management.

    
                    gateway local console main menu screen with configuration options
                        listed.
  3. On the System Time Management menu, enter 1 for View and Synchronize System Time.

    
                    gateway local console system time management screen.
  4. If the result indicates that you should synchronize your VM's time to the NTP time, enter y. Otherwise, enter n.

    If you enter y to synchronize, the synchronization might take a few moments.

    The following screen shot shows a VM that doesn't require time synchronization.

    
                    time synchronization test results showing acceptable disparity of less
                        than one second.

                        than sixty seconds.
