444 Troubleshooting and Recovery
CMC provides tools to troubleshoot these problems, with the primary source
of troubleshooting information being the CMC Trace Log. This log contains
an error message for NTP related failures. If CMC is unable to synchronize
with any of the remote NTP servers that have been configured, then it derives
its timing from the local system clock.
If CMC is synchronized to the local system clock rather than a remote time
server, the trace log contains an entry similar to the following:
Jan 8 20:02:40 cmc ntpd[1423]: synchronized to
LOCAL(0), stratum 10
You can also check the ntpd status by typing the following racadm command:
racadm getractime –n
If an ‘*’ is not displayed against one of the configured servers, something may
not be set up properly. The output of the above command also contains
detailed NTP statistics that may be useful in debugging why the server does
not synchronize. If you attempt to configure an NTP server that is Windows
based, it may help to increase the MaxDist parameter for ntpd. Before
changing this parameter, read and understand all implications of doing so,
especially since the default setting should be large enough to work with most
NTP servers. To modify the parameter type the following command:
racadm config –g cfgRemoteHosts –o cfgRhostsNtpMaxDist 32
After making the change, restart the ntpd by disabling NTP, waiting 5-10
seconds, then enabling NTP again.
NOTE: NTP may take an additional 3 minutes to try and synchronize again.
To disable NTP, type:
racadm config –g cfgRemoteHosts –o cfgRhostsNtpEnable 0
To enable NTP, type:
racadm config –g cfgRemoteHosts –o cfgRhostsNtpEnable 1
If the NTP servers are configured correctly and this entry is present in the
trace log, then this confirms that CMC is unable to synchronize with any of
the configured NTP servers.
There may be other NTP related trace log entries to assist in your
troubleshooting effort. If it is a NTP server IP address misconfiguration
problem, you may see an entry similar to the following:
