How to Add NTP Server to Data Domain
# ntp disable
# ntp add timeserver <time server list>
For example: # ntp add timeserver 192.168.1.10
# ntp enable
How to Set Time Manually if there is a Mismatch between NTP server and Data Domain
# ntp disable
# system set date <MMDDhhmmYYYY> – Change DD time as of the NTP server:
Example to set system date/time to 0930 on 25th March 2018 the following command would be used:
# system set date 032509302018
** System date will be adjusted by xxxxxx seconds. This change can
potentially cause issues for applications running on this system.
Are you sure? (yes|no|?) [no]: yes
ok, proceeding.
