Cause

• This warning is caused by latency being high on the device on Storage

Resolution

• This message can be safely ignored 
  
  
• If message is repetitive in then below parameter can be set Site Recovery DR page as workaround 
  • Increase the timeout value for the SRM in the Advanced settings of the SRM UI, on both sites of the pairing.
    • In the vSphere Client, click Site Recovery > Site Recovery home tab, select the Site Pair > Remote Manager > EDIT 
    • The maximum values can be set for remoteManager.taskDefaultTimeout = 3600  ( Default value is 900)
