Configure NTP Servers and Services Using the CLI
You can use the CLI to add or update a list of servers and services.
NTP Servers
You can specify up to three servers using the CLI or the Horizon Web
interface. For more information, see Configure NTP Servers and Services Using Horizon <configuring-ntp-servers-and-services-using-horizon>.
To view the existing server configuration, use the following command.
~(keystone_admin)$ system ntp-show

+--------------+----------------------------------------------+Note
When you change the system configuration you must lock/unlock all hosts. This process requires a swact on the controllers. During a host swact the system may raise alarms.
To change the server IP addresses, use the following command syntax. The ntpservers option takes a comma-delimited list of server names.
~(keystone_admin)$ system ntp-modify \
ntpservers=<server_1[,server_2][,server_3]>For example:
~(keystone_admin)$ system ntp-modify ntpservers=0.pool.ntp.org,1.pool.ntp.org,3.pool.ntp.orgNTP Service
Clock synchronization, synchronizes time across multiple systems in a network. The default value for clock_synchronization is ntp.
Note
and is configured per host. Lock/unlock the host when updating clock_synchronization for the host.
Use the following command to change the clock synchronization on the host:
~(keystone_admin)$ system host-update controller-0 clock_synchronization=ntp
