Hello, I'm not sure NetApp would query any of those disks, since no Support would be in place for anything not in Contract. If you wish to purchase second hand disks, then Caveat emptor.
The system will inform you of any non-NetApp disks added to the system regardless of whether Support is in place or not, however if you decide to extend your Supported aggregate by another RAID group of NetApp disks purchased second hand and therefore out of Contract, then this will be at your own risk.
Any disk(s) supplied from NetApp (or it's partners) will be fully supported until either its End of Hardware Support date or the lapse of the Support Contract.
If I've misunderstood your question then please advise.
Thanks,
Grant.
