Datastore inactive Vmware/Vsphere

We had a transformer blow last night and lost power resulting in total power loss of all our equipment after the battery ran down. Of the four ESXi servers we have one of them is showing three datastores that are not active. They just show inactive. The other three ESXi servers can see them just fine. I right clicked the server and did a rescan for datastores and they came back just fine. I would like to migrate running VMs from one server to another server but now it shows me

Unable to access the virtual machine configuration: Unable to access {datastore} virtualmachine/vm.vmx

If I select another server it sais validation succeeded. What gives?

That particular host seems to be having difficulty reading the configuration file.

try another re-scan/refresh, and also it may be worth, restarting vCenter Server server service.

This will not affect VMs.

can you confirm host3, definitely has access to the datastore?

via SSH or Console if necessary.

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

It can see it

[root@esx06:/vmfs/volumes/556d5d4d-fa354c92-e606-44a84218a1b3] ls -al

I can see all the VMs on that store.

The error message on that window in vsphere says Unable to acess the virtual machine configuration
Unable to access virtual disk either the host is disconnected from the data store or has insufficient privileged

Move all VMs, off that host, and restart it.
