On Windows Server 2008/2012, you can only access file shares pointing to local disks with the physical computer name. To be able to define file shares pointing to shared disks, a "client access point" (one IP address associated with one network name cluster resource) must already exist in the failover cluster service group to which the shared disk belongs. Since you can only access file shares pointing to shared disks with the network name that belongs to the same failover cluster service group, you can create multiple file shares with the same file share name (for example, sapmnt) in a failover cluster environment, assuming the file shares belong to different cluster service groups.
