Goal

 It is often useful to be able to completely and permanently remove data from hard disks.

Solution

The appliance does not have any specific method to wipe the drives.  Depending on how deep you want to wipe it out, there are a couple of things you could do.

1)  If the drives need to be thoroughly wiped, you could pull the drives and install them into another system and perform a DoD level wipe.

This document describes the process for doing this function with disks installed in a system outside of the zfssa array environment:

How to Remove Sensitive Information / Data from Your Hard-Disk Using the Format Utility (Doc ID 1008773.1)

2)  Unconfigure the pools, create a new pool using all drives in a triple mirror and encrypt the pool. You could then load random data on the pool and then destroy the encryption key,

See this document:

Oracle ZFS Storage Appliance: How To Use Encryption To Safely Secure Data, Ship Disks Or Appliance Without The Key, Then Restore The Key (Doc ID 2043971.1)

3)  Mount the shares/LUNs and wipe the data from the client side.  Pool structure would remain intact, so this may not be necessarily considered a "secure" erasure.

4)  For some situations the only acceptable solution to meet the specific customer requirement is to take the drives and run them through special shredders/disk destroyers.

There is an open RFE Bug for this feature: ENH 15790402 - SUNBT7167280 Disk wipe
