On a MountInst object -- an NFS mount that UCS Manager has set up (for example a remote share used for backup images, firmware, or ISO repositories) -- cucsNfsMountInstOperState is an enumerated state/type value reporting the current operational state (e.g. mounted, unmounted, or failed) of this mount/interface object. An admin reads this enumeration because it distinguishes between the specific operating modes or states that a MountInst instance can be in, which affects how UCS Manager and connected hosts behave. For example, an admin diagnosing behavior on a particular MountInst instance would check cucsNfsMountInstOperState to see which specific mode or state is currently configured or active.
