Recover NAS System Volume

Overview

This function recovers the NAS system volumes (RootFS) that are used by the target NAS Engine and forcibly enables the NAS Engine.

A "RootFS" is a volume that stores the root file system of the NAS Engine in each CM. If a malfunction occurs in the NAS Engine due to an inconsistency between the both RootFSs, use this function to recover the RootFS and forcibly enable the NAS Engine again.

This function is displayed in a Unified Storage environment.
