Thanks, that is exactly what I wanted. It is too bad that one has to go round about way of accomplishing this. An argument to the spares_zero command would do the trick.

I have few disks (now spares) that used to belong to a volume that was destroyed, however, I MUST zero out any data from these disks before they can leave our premises.

George,

The NetApp Zeros the disks in parallel so the time it takes to zero 1 disk should be the same as 7 disks. If you really do not want to zero the other spares out you could pull them from the filer and then run the command to zero all and then place the none zeroed disk back in. Hope this helps.

Thank you,

William Atherton

Does anyone know how you can zero out a specific disk(s) ? The "disk zero spares" command or "spares_zero" diagnostic command seem to zero out ALL spare disks only.

Thanks, George
