Unity 300F Erase / Sanitize drives

Question

Hi, I am replacing my old Unity 300F with an Unity 450F and I was wondering if there was anything special I have to do in order to erase the data on my drives. I know that deleting the NAS shares and servers and then the pool will at a hight level delete the data but is that enough to actually scrub the disks? The Pool was created using RAID-5 so if I create a new Pool with a different RAID set will that be enough? Thank you. Herb

creating a pool wont zero the disks blocks

you would need to create LUNs and overwrite all the data

but even that will not guarantee that every block is overwritten

for example it wont touch the areas reserved for OE and config

the PS service uses special software that the array boots instead of Unity OE

If you have DARE yo could look at kb 487661

professional service does offer a secure erasure service for Unity deleting a LUN / fs / NAS server does not delete its data on disk - it wont overwrite it with zeros

Thank you for your response. What about deleting the pool and creating a new one using a different RAID type?
