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) -- cucsNfsMountInstPurpose is an enumerated state/type value reporting the intended purpose UCS Manager assigned to this NFS mount (such as backup or image repository use). 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 cucsNfsMountInstPurpose to see which specific mode or state is currently configured or active.
