securely wiping old shelves and disks

mcrossley — Thu, 05 Jun 2025 05:26:22 GMT

Hi all,

We're upgrading our system soon, entirely new head and shelves. We have some old DSMk2 FC shelves that I will need to get rid of. What's the most secure way for me to wipe the data that's on those a disks? We would likely have them destroyed anyway, but I would like to securely wipe them before they go out the door.

How securely do you want these erased? I think you can you delete the aggregate they're part of, make them spares, then run "zero disk spares"...

Search for the term "disk sanitization" on the library or support websites. This is a way of securely erasing all the data on a disk drive by overwriting each block. You can run it with various options depending on your requirements and these might be OS version dependant which is why I haven't inluded a specific link.

Cheers
