Hello ,
We have two Node Hyper-V 2016 Clusters with Dell Storage .
Suddenly some VMs rebooted unexpectedly
From Event Viewer following result found , tried to search on Google but could not found root cause why they got rebooted .
Checked also from Dell Storage events and Hosts Hardware Events from iDRAC , but nothing suspected found from Storage and Hosts side.
Both Hosts have equally amount of RAM distributed VMs running. and VMs were on Different CSV those were rebooted.
Any help would be more appreciated.
