Hi,

This typically occurs when the time between the DFM server and the controller is greater than 60 seconds. There are a few ways to address it.

  1. Try to point the controllers and DFM server at the same time server and ensure that the
    controllers are configured for NTP.
  2. Adjust the thresholds in DFM as covered in the following article.
    https://kb.netapp.com/support/index?page=content&id=1013384 The article covers setting at the global level.
  3. You might be hit by Bug 638586

    Hope this helps.

Hello Renifa

 

Thanks for your repy,I checked time server , it is the same one on controllers and DFM server .

The controller time is behind DFM server time .It is alose behind the other one controller .

 

The threshold setting is  30 second on DFM server .

hostClockNearlySkewedThreshold 30 seconds

 
I think the controller time is wrong .Could you tell me how to update the controller time .
Do I need set timed.enable off ,and update the time manually ?
 
Thanks.
