I know the queston regarding Shreding the disk is clear in VSP & newer arrays, however, i am not finding any information on older array if shreding is option or not, i only see "invalidate" or format options on the parity groups, did i miss it anywhere.

Perhaps its cmd line or availlable to CE only , i need to determine if i need to use host based shreding option or does HDS offer something likewise.

Appriciate your answers.

Thanks
