After I had a datastore failure I needed to ‘unmount’ a datastore in my VMware 6.5 environment. But when I attempted to do so I got;
The “Remote Datastore” operation failed for the entity with the following error message.
The resource “Datastore-Name” is in use.
In use by what? Thanks for the assistance! Usually this happens because you have a VM with a VMDK in their datastore, or more likely, a VM has a CD mapped to an ISO that was in this datastore (which was my problem).
In “Datatstore View” > Select the offending Datastore > VMs > Eliminate them one by one.
