isilon flexprotect job phases

It seems like how Flexprotect work is a big secret. As mentioned previously, the FlexProtect job has two distinct variants. FlexProtectLin runs by default when a copy of file system metadata is available on SSD storage. Typically such jobs have mandatory input arguments, such as the Treedelete job. By comparison, phases 2-4 of the job are comparatively short. Requested protection settings determine the level of hardware failure that a cluster can recover from without suffering data loss.
