My advise would be to get in touch with your NetApp Account Manager . I am sure there must be some contact through which you had purchased NetApp E2700.
I can see this Disk in HWU, but I would recommend get in touch with your NetApp Account Manager. Usually, if its under support, NetApp sends the replacement, have you contacted NetApp?
On intenet, I see this Disk is Branded by both SEAGATE & DELL, basically both provides their version of Firmware (even though the Hardware is same). Obviously, when it goes inside NetApp shelf, it will need to be updated with NetApp Firmware for that Drive but the question is will it be supproted ?
If its very urgent, I suggest call up support and ask them for direction. Hopefully someone with more knowledge on this from NetApp community will guide you further.
