2-102 SPARC Enterprise Mx000 Servers XSCF User’s Guide • January 2012
Of the two NTP server outputs, the upper (192.168.1.2) indicates the NTP server
which is set by using the setntp(8) command. The refid is LOCAL(0), which means
that the local clock which has the address of "127.127.1.0" is set to the clock source of
this NTP server. On the other hand, the lower indicates the XSCF's own local clock.
The address of the XSCF's own local clock is fixed to "127.127.1.0."
Due to this, the NTP server (192.168.1.2) is excluded from the target of XSCF time
synchronization; which results in the XSCF synchronizes with its own local clock.
With any of the following measures to avoid the trouble, time can be correctly
synchronized with the NTP server which is set by using the setntp(8) command.
a. Change the clock source that the NTP server being set in XSCF refers to
Use the showntp -l command and check the clock source of the NTP server
which is set in XSCF. An NTP server which indicates the refid of LOCAL(0) in the
output is referring to the local clock which has the address of "127.127.1.0," and
you should change it to refer to another clock source.
When you change the clock source of an NTP server, make sure in advance that it
has no impact on other NTP clients.
b. Change the address of the local clock of the NTP server
Of the NTP server which XSCF refers to, change the address of the local clock to
"127.127.1.1," "127.127.1.2," or "127.127.1.3." Change /etc/inet/ntp.conf of
Oracle Solaris OS. To enable the change, restart of the NTP daemon is required.
When you change the address of the local clock of an NTP server, make sure in
advance that it has no impact on other NTP clients.
c. Change the stratum value of the NTP server
Of the NTP server which XSCF refers to, change the stratum value to "1." An NTP
server which has the stratum value of "1" becomes the most significant clock
source and has no refid. Therefore, there is no chance that it will have the same
address as the XSCF's own local clock.
When you change the stratum value of an NTP server, make sure in advance that
it has no impact on other NTP clients.
d. Change the address of the XSCF's own local clock
By using the setntp -m localaddr=value command, change the address of
the XSCF's own local clock. In value, specify the least significant byte of the
clock address of the local clock 127.127.1.x for value. A numeric from 0 to 3 can be
