Hi @Terry-Lui 

Potentially one of the nodes rebooted/paniced and restarted which why things look good now. 

Can start by doing a health check of some kind - https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/How_to_perform_a_health_check_in_Data_ONTAP_8_7-mode (requires active login to Support Site)

Hope this helps point you in the right direction.

Usually, the SP logs would help with an unexpected reboot (What logs to collect for a down system with a Service Processor - NetApp Knowledge Base) Specially the console logs, which would show what was the last message of the node before going down (SP> system log).
