ECKD shop here... Nothing wrong with that - Where are your 2 lpars? Why can't they share? If you do not have physical access to both, you will need to replicate it over a network. What that network is depends... You can send it over an IP with DRBD. You can replicate it with HW with PPRC. I doubt you'd want to stop PPRC for a server blip though.. That's a whole nother set of fun. But way easier if you can just cable both those CECs to the same local eckd dasd. You can set up your NFS server to use the SLES High Availability Extensions and move that function from one server to another. But, the one waiting in the wings has to have file system available to him.
I'm not sure how writes in progess would deal with this though. I guess using NFS it would just fail on the client side and he'd have to retry his work. You might want to google HA NFS and see what things others are doing to support that.
