In the VV view of MC, does "Reserved Copy Size" ( GiB or % Virtual ) have any relation to the Copy CPG? As far as I know, on our F400 frames, we never utilized snapshots, which is a license-able product I believe? Trying to cleanup predecessors work and noticed nearly all the VVs have a CopyCPG set to the same CPG as the VV??...maybe they thought you had to do it? Or thought it was some sort of extra protection? If one were to make a Physical or Virtual Copy of a VV, would a CPG be needed then? |

Copy CPG is required for virtual copies as well as remote copy. Not sure about physical copies, but its possible if the physical copy uses a snapshot as its source copy. On our systems that have no virtual/remote copies, we clear the copy field field. |

I've seen in the best practice guide it recommends you do set a copy CPG for each VV. It doesn't say why, I guess its just so that if you do start to use snapshots etc in the future the setting is already there. So I would think that's why the copy CPG setting is there on your system. |
