This is the Relative Name (Rn) of a MountInstFsmStage object -- the naming property that, combined with its parent's Dn, distinguishes one MountInstFsmStage 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 one individual stage/step inside that NFS-mount FSM task, useful when comparing several sibling instances that share the same parent container. For instance, when a UCS host has several MountInstFsmStage instances defined, the Rn is what separates "this one" from "that one" without needing the entire Dn string.
