Chapter 2 Setting Up XSCF 2-41
■ A Solaris OS domain can be set up as an NTP client with the XSCF Unit being the
NTP server. In this case, the XSCF Unit must be set up as an NTP server (see
Configuring an NTP Server ). In this case, the Solaris OS domain will obtain its
initial time-of-day from the XSCF NTP server, which will then be used to keep the
Solaris domain and the XSCF unit in sync.
■ A Solaris domain can be set up as an NTP client from an external NTP server. In
this case, the initial time for Solaris OS will be obtained from the XSCF Unit. If
you connect the domain to an external NTP server, connect a high rank NTP
server that supplies the time at the same accuracy for the domain as for XSCF.
■ If you use the Solaris OS date command to set the time on a Solaris OS domain,
the time offset between the Solaris OS domain and the XSCF Unit will be
preserved over reboots. Whenever the Solaris OS domain boots, its initial time-of-
day will be the XSCF Unit time adjusted by the time offset created the last time
the Solaris OS date command was used on the domain.
TABLE 2-7 lists the settings and the corresponding shell commands.
