This Whitepaper gives an introduction to the IBM Spectrum Scale™ immutability function. It explains what it is and shows different ways for managing immutable and append-only files It further provides guidance and best practices for configuring IBM Spectrum Scale in a secure manner. Finally this document demonstrates two typical use cases managing immutable files. One use case involves applications that manage file immutability and another use case presents a solution to automatically set files to immutable within a Spectrum Scale immutable fileset.
