Hi,
Actually i am also a netapp owner from ghetto shop (aka ebay)
My personal expierience is:
1) You will never get anything license/ownership related from NetApp. Just forget it ... you are on your own and possibly independant consultants ... probably second is not an options as i guess.
2) Controllers without licences can only be used as a decoration. (this does not apply to HDDs and other usefull parts)
3) It is possible to google and find installation images on internet. FAS2040 will run 8.1.4P9 (latest) filename to look for: 814P9_e_image.tgz or .zip (.zip if upgrading from v7.x.x)
If your system is totally dead then you will need to look for netboot image.
4) I would recomment buying FAS2040 (even 1 controller will do) with drives and licences present/available from seller and then make dual controller filer. .... and get spare power supplies.
5) 6x 300GB drives is total BS .... you will end up with is <900GB usable space if your volumes will be mounted on root aggregate (not recommended).
(1xHS, 2xparity, 3xusable). Go for 8 drives (any size) in head unit and normal 14x450GB 15K FC shelf DS14mk4.
P.S. Btw i have spare FAS2020 (dual controller) 12x 300GB 15K SAS with some licences on it. Maybe you are interested ... if located in Europe shipment is not a problem.
Of course FAS2020 is not a dream machine, but it has drives (you need) and licences you need even more 😉
