Hello,
In reading your post, you are referring to "Nodes" as being the servers. All your screenshots and error messages appear to be from the server side. You have posted this topic in the MSA Storage forum. You might want to try reposting in the server forum.
As a suggestion be sure your multipathing configuration is correct. To have a server/node shutdown and the VMs not failover is an indication that multipathing from the server or host OS perspective is not correctly set.
This does not appear to be an MSA Storage issue.
Cheers,
Shawn
