Wiping hard drives in an IBM DS3512

hard drivehardware-raidibmraidsas

I have an IBM DS3512 RAID storage device, which I'm planning to sell. How would I reliably wipe my data off of all the hard drives?

As far as I can tell, it abstracts away all direct access to the drives, so running a data wipe program on the RAID partitions wouldn't necessarily work. The only option I see is to manually remove each drive, attach it as an external drive via a SAS-to-USB adapter, and wipe it that way. Is there a better option?

Some common methods, you have to see what your model supports:

  • Export all drives as JBOD. You'll end up with n drives you can wipe separately.
  • Export them as RAIDx with max capacity, again without a spare. If you see a drive with the expected capacity in the OS, wiping this should also destroy all data.
  • See if the controller offers a specific feature for data wiping.
  • Sell only the case without drives if you are really concerned.
