Hi I am considerable new to ESXi and to this forum. Background of the problem, I have 4 virtual machine: Windows 7, Windows 10, Linux and etc. I was copying a 30GB iso file to datastore last night. When I woke up I found the datastore browser in webclient is timing out so I'm not sure the 30GB upload had been completed. Then I put to maintenance mode so I can restart the host. However after restarting then I found that all of my 4 virtual machine become in accessible, see below screenshot. Please assist what is the next step? Thanks.
