c. The HP-UX PV2 client returns an [EFBIG] error if the requested file is > 2 GB-1.
d. The HP-UX PV2 server returns an [NFSERR_FBIG] error if a large file is encountered
(on getattr(), setattr(), lookup(), read(), write(), and create() calls).
e. The HP-UX PV3 server returns [NFS3ERR_FBIG] if the request (read(), write(),or

system.
f. The HP-UX PV3 client returns an [EFBIG] error if the requested file is larger than
the remote file system’s maximum file size.
g. The HP-UX PV2 server returns an [NFSERR_FBIG] error if a large file is encountered
(on getattr(), setattr(), lookup(), read(), write(), and create() calls).
h. The HP-UX PV2 client maps [NFSERR_FBIG]to[EOVERFLOW] in cases where a remote
large file is encountered.
i. The HP-UX PV3 server returns [NFS3ERR_FBIG] if the request (read(), write(),or
create()) exceeds the maximum supported size of the underlying HFS/JFS file
