Set NTP settings on a Dell server with iDRAC7

Set the DNS first to ensure the iDRAC can resolve the NTP host names:
racadm -r 10.1.1.100 -u root -p calvin set idrac.ipv4static.dns1 8.8.8.8

Set the NTP server names:
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.ntp1 0.asia.pool.ntp.org
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.ntp2 1.asia.pool.ntp.org
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.ntp3 2.asia.pool.ntp.org

In case it won’t update the time when FQDN’s are used, IP addresses can also be used:
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.ntp1 129.250.35.250
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.ntp2 180.211.88.50
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.ntp3 202.112.29.82

Enable NTP and set max hops:
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.NTPEnable Enabled
racadm -r 10.1.1.100 -u root -p calvin set idrac.NTPConfigGroup.NTPMaxDist 16

Set the timezone:
racadm -r 10.1.1.100 -u root -p calvin set idrac.time.timezone Japan
