This is the Relative Name (Rn) of a MountInstFsm object -- the naming property that, combined with its parent's Dn, distinguishes one MountInstFsm instance from its sibling instances under the same parent. An admin cares about the Rn because it is the local, human-readable piece of the path for the finite-state-machine (FSM) task UCS Manager runs while it mounts, unmounts, or validates that NFS mount, useful when comparing several sibling instances that share the same parent container. For instance, when a UCS host has several MountInstFsm instances defined, the Rn is what separates "this one" from "that one" without needing the entire Dn string.
