NFS lookup failed for server netapp

Hi

When trying to mount a database from Solaris, we get the error:

Feb 10 09:27:22 SUNTEST nfs: [ID 664466 kern.notice] NFS lookup failed for server netapp: error 11 (RPC: Server can't decode arguments)

Feb 10 09:27:27 SUNTEST nfs: [ID 664466 kern.notice] NFS getattr failed for server netapp: error 11 (RPC: Server can't decode arguments)

Permissions on the NFS exports are set as Root/Read&Write/Security for the Sun Host.

We can create new files on the volume, just cannot start the DB...
