The best way to handle NFS mounting of a device with Oracle is to talk to the hardware vendor. NetApp and EMC will provide the appropriate, and supported connection string. I am sure others will too.

Here is a sample of what NetApp provided for an F810 in my lab. mount –t nfs –o
rw,bg,hard,intr,rsize=32768,wsize=32768,noac,nolock,tcp,vers=3 10.128.1.4:/vol/vol0 /mnt
