Data ONTAP puts SnapValidator options in a known state when you upgrade or revert the Data ONTAP software.
When you upgrade to Data ONTAP 7.0 or greater from a release prior to Data ONTAP 7.0, all SnapValidator options on all volumes are disabled. The offset attribute (the svo_offset option) for LUNs is also disabled.
When you revert to a previous version of Data ONTAP, all SnapValidator options on all volumes are disabled. The value for the LUN offset is retained, but the earlier version of Data ONTAP does not apply it.
