A RAID level-6, level-5, level-5EE, level-50, or level-60 logical device moves to the Impacted state if a drive fails during initialization or the initialization process is stopped before it completes. This may occur during build or background consistency check (with background synchronization). In an Impacted drive, the striping/synchronization process has not completed and you need to resynchronize.
Note:
A RAID level-1, level-1E, or level-10 logical device moves to the Impacted state
during its initial build. When the build is complete, it returns to the optimal state.
