Configure NTP synchronization in your environment (2149170)

  • 0 Ratings

Details

If you upgrade vSphere Replication 5.8.1.3 or later directly to vSphere Replication 6.1.2, you must synchronize the time on the vSphere Replication appliance in your environment with an NTP server.

Solution

By default, the vSphere Replication appliance is synchronized with the ESXi host on which it resides. You must disable the NTP synchronization with the host and configure the vSphere Replication appliance and the vCenter Server to synchronize with an external NTP server.

  1. Configure NTP synchronization on the vSphere Replication appliance.
    1. In the vSphere inventory tree, locate the vSphere Replication appliance, right-click and select Edit Settings.
    2. On the VM Options tab, click VMware Tools.
    3. Deselect the Synchronize guest time with host check box.
    4. In the virtual appliance console, run the command systemctl enable ntpd to run NTP synchronization every time the vSphere Replication appliance starts up.
    5. To configure the vSphere Replication appliance to synchronize with an NTP server, edit the /etc/ntp.conf file to enter the address of an NTP server.

      Add the following line in the ntp.conf file:

      server <your_ntp_server_address>
    6. Run the command service ntpd restart.

  2. Configure the vCenter Server on the source site to synchronize with the NTP server that you configured in the vSphere Replication appliance.
