Add or Replace NTP Servers in the vCenter Server Appliance Configuration
To set up the vCenter Server Appliance to use NTP-based time synchronization, you must add the NTP
servers to the vCenter Server Appliance conguration.
Procedure
1 Access the appliance shell and log in as a user who has the administrator or super administrator role.
The default user with super administrator role is root.
2 Add NTP servers to the vCenter Server Appliance conguration by running the ntp.server.add
command.
For example, run the following command:
ntp.server.add --servers IP-addresses-or-host-names
Here IP-addresses-or-host-names is a comma-separated list of IP addresses or host names of the NTP
servers.
This command adds NTP servers to the conguration. If the time synchronization is based on an NTP
server, then the NTP daemon is restarted to reload the new NTP servers. Otherwise, this command just
adds the new NTP servers to the existing NTP conguration.
3 (Optional) To delete old NTP servers and add new ones to the vCenter Server Appliance conguration,
run the ntp.server.set command.
For example, run the following command:
ntp.server.set --servers IP-addresses-or-host-names
Here IP-addresses-or-host-names is a comma-separated list of IP addresses or host names of the NTP
servers.
This command deletes old NTP servers from the conguration and sets the input NTP servers in the
conguration. If the time synchronization is based on an NTP server, the NTP daemon is restarted to
reload the new NTP conguration. Otherwise, this command just replaces the servers in NTP
conguration with the servers that you provide as input.
4 (Optional) Run the command to verify that you successfully applied the new NTP conguration
seings.
ntp.get
The command returns a space-separated list of the servers congured for NTP synchronization. If the
NTP synchronization is enabled, the command returns that the NTP conguration is in Up status. If the
NTP synchronization is disabled, the command returns that the NTP conguration is in Down status.
What to do next
If the NTP synchronization is disabled, you can congure the time synchronization seings in the
vCenter Server Appliance to be based on an NTP server. See “Synchronize the Time in the vCenter Server
Appliance with an NTP Server,” on page 44.
Synchronize the Time in the vCenter Server Appliance with an NTP Server
You can congure the time synchronization seings in the vCenter Server Appliance to be based on an NTP
server.
Prerequisites
Set up one or more Network Time Protocol (NTP) servers in the vCenter Server Appliance conguration.
See “Add or Replace NTP Servers in the vCenter Server Appliance Conguration,” on page 44.
