Although you can delete the datastore without unmounting, it is preferable that you unmount thedatastore first.Prerequisites• Remove or migrate all virtual machines from the datastore.• Make sure that no other host is accessing the datastore.• Disable Storage DRS for the datastore.• Disable Storage I/O control for the datastore.• Make sure that the datastore is not used for vSphere HA heartbeating.• Browse to Datastores in the vSphere Web Client navigator.
