Chapter 4 Configuring the CDS
Server Level Configuration
Other NTP Configurations
In addition to configuring the IP addresses of the NTP servers, you need to set the time zone on each
CDS server, as well as configure the NTP servers for the CDSM and VVIM.
Setting the Time Zone on a CDS Server
To set the time zone on a CDS server, log in to the CDS server as root, and use the Linux link command
to link the time zone to the /etc/localtime file.
The following are examples of the command used to set UTC and several different US time zones:
• UTC option:
ln -sf /usr/share/zoneinfo/UTC /etc/localtime
• EST option:
ln -sf /usr/share/zoneinfo/US/Eastern /etc/localtime
• Central option:
ln -sf /usr/share/zoneinfo/US/Central /etc/localtime
• Mountain option:
ln -sf /usr/share/zoneinfo/US/Mountain /etc/localtime
• Pacific option:
ln -sf /usr/share/zoneinfo/US/Pacific /etc/localtime
Find the time zone for your specific location in the /usr/share/zoneinfo directory.
Configuring the NTP Server on the CDSM and VVIM
Configuring the NTP server on the CDSM or VVIM involves the following:
1. Adding the NTP servers to the /etc/ntp.conf file
2. Setting the run levels for the Network Time Protocol daemon (ntpd)
3. Setting the time zone
4. Setting the server date and time
5. Starting the NTP service
6. Synchronizing the server clock with the NTP server
7. Synchronizing the hardware clock on the server
Specific NTP configuration details should be obtained from your system administrator to add the NTP
servers to the /etc/ntp.conf file.
To setup the NTP server on the CDSM or VVIM, do the following:
Step 1 Log in to the CDSM or VVIM as root.
Step 2 Set the run levels for the NTP service.
# chkconfig --level 2345 ntpd on
To check the run level settings, enter the following command:
# chkconfig --list ntpd
