Using vSphere 5.5, with 3 esxi .
in Esxi1, i have a VM stored in a synology nas, called Unitrends. Yesterday, after the NAS had a power shortage, when i tried to restart the machine (without knowing at the time that the storage was not available), the name changed to /vmfx/volumes/530773a-4e463....... (inaccessible).
I powered back on the Synology NAS, and checked that the All Path Down error messages are cleared, and can browse the datastore. Still, i don't know how to rename this back to it's original name, and power on the machine...
