Removing data from disks using selective disk sanitization
The procedure you use to selectively sanitize data depends on whether your data is contained in FlexVol or traditional volumes.
More information
Selectively sanitizing data contained in FlexVol volumes
To selectively sanitize data contained in FlexVol volumes, you need to migrate any data that you want to preserve in the entire aggregate, because every disk used by that aggregate must be sanitized.
Selectively sanitizing data contained in traditional volumes
To selectively sanitize data contained in traditional volumes, you migrate any data you want to preserve to a new volume, and then sanitize the disks that contained the old volume.
