this error in all VMs
Cannot open the configuration file /vmfs/volumes/54e08812-2a44c8b0-058c-2c27d7149a1c/ISA/ISA.vmx.

Can I request a screenshot of your VM folder, to assist you.

Is there any space on the datastore ?

On this example VM, SQL there is a snapshot associated with the VM.

It's possible that this could be the cause of the issue.

Can you screenshot another VM folder, if others are running on a snapshot.

Did the host crash, when backups were being run ?

As an aside 50GB is very low space on a datastore, and you should aim, to keep 20-30% free.

also this error from another vm
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Okay, looking at the example VM - File, this is odd, because there is a vswp file on the datastore, and these should only be present if the VM is Powered On.

Can you remove the vswap files ?

I'm wondering if the VMFS datastore has been corrupted, and is read only.
TemodyPickalbatros, IT ManagerAuthor Commented:

TemodyPickalbatros, IT ManagerAuthor Commented:

Thanks andrew for help

I had the same issue, however to solve it i created a new virtual machine with the same properties as the corrupted virtual machine.
I did not create a new virtual disk, instead i used to the same virtual disk as the previous virtual machine, thus i still had access to all my
previous files and configurations.
