NOTE: NTP may take an additional three minutes to 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 not able to
synchronize with any of the configured NTP servers.
If the NTP server IP address is not configured, you may see a trace log entry similar to the following:
Jan 8 19:59:24 cmc ntpd[1423]: Cannot find existing interface for address 1.2.3.4 Jan 8
19:59:24 cmc ntpd[1423]: configuration of 1.2.3.4 failed
If an NTP server setting was configured with an invalid host name, you may see a trace log entry as follows:
Aug 21 14:34:27 cmc ntpd_initres[1298]: host name not found: blabla Aug 21 14:34:27 cmc
ntpd_initres[1298]: couldn't resolve `blabla', giving up on it
For information on how to enter the gettracelog command to review the trace log using the CMC Web interface, see Using
Diagnostic Console.
Interpreting LED Colors and Blinking Patterns
The LEDs on the chassis provide the following status of a component:
• Steadily glowing green LEDs indicate that the component is turned on. If the green LED is blinking, it indicates a critical but routine
event, such as a firmware upload, during which the unit is not operational. It does not indicate a fault.
• A blinking amber LED on a module indicates a fault on that module.
• Blue, blinking LEDs are configurable by the user and used for identification. For more information about configuration, see Configuring
LEDs to Identify Components on the Chassis.
