Well, if you're just playing, you could certainly try to just add a new entry to the qual_devices line and see what happens. But you'll be on your own.
Julian> And if these disks are supported is it possible to mix 10k & Julian> 15k drives? I really just want the full capacity of the Julian> drives.
There's no real reason they won't work together, it's just that Netapp won't support you if something goes wrong. *grin*
From the look of the file, all you'd need to add is a line like this:
D SEAGATE ST336753FC 0002 512
and see what happens. you might need a reboot to make it take effect after you do the edit. The key is probably the '512' part, since you don't want to mess around with the Zone Checksums (or is it block? I can't remember...) since you disk most likely is setup for 512 byte blocks, not the 520 byte blocks.
Good luck, John
