System Manager 11.70.2 - Synchronize storage array clocks

If Network Time Protocol (NTP) is not enabled, you can manually set the clocks on the controllers so they are synchronized with the management client (the system used to run the browser that accesses ThinkSystem System Manager .

About this task

Synchronization ensures that event time stamps in the event log match time stamps written to the host log files. During the synchronization process, the controllers remain available and operational.

Note: If NTP is enabled in System Manager , do not use this option to synchronize clocks. Instead, NTP automatically synchronizes the clocks with an external host using SNTP (Simple Network Time Protocol).

Attention: After synchronization, you might notice that performance statistics are lost or skewed, schedules are impacted (ASUP, snapshots, etc.), and time stamps in log data are skewed. Using NTP avoids this problem.

Select Settings > System .
Under General , click Synchronize Storage Array Clocks .
The Synchronize Storage Array Clocks dialog box opens. It shows the current date and time for the controller(s) and the computer used as the management client.
If the times shown in the dialog box do not match, click Synchronize .

What happens next?

After synchronization is successful, event time stamps are the same for the event log and host logs.
