This is a new one for me. Today I performed a storage vMotion on a server. The server has multiple discs, but I only needed to move one of them. The migration completed and I thought all was well, but then I noticed something weird. That same server shows up as a vm on a totally separate datastore than I migrated from. Not only that, but there are no files associated to the datastore. Let me explain a little further...
esx_datastore_1 Original location of hard disc files
esx_datastore_2 New location files were successfully moved to
esx_datastore_3 Location which shows connected vm, but has no associated files 
I discovered the empty datastore after attempting to migrate everything back, but I received an error that the .vmdk file was missing. I checked the settings if the vm...none of the discs reference the esx_datastore_3. The server appears to be running with no problems, but I don't like the feeling that it appears to be connected to a datastore it has no files located on. Any ideas?
