Hi Jose

you dont need to migrate .
the detault nfs version on hp-ux 11.X is NFS PV3 .

the only way is to migrate is in hp-ux 10.20 , over there you need to install all the nfs patches to migrate to PV3 .

PV3 is support PV2 .

Hi Eran,

Thanks for reply.

The case is that the NFS version shows version=2
rpcinfo -p |grep nfs
100003 2 udp 2049 nfs

Hi Jose

please check this doc :

On the NFS client, the command nfsstat -m displays several flags,
among which, is the vers= flag. This is the NFS version of the mount.


/mountpoint from NFSserver10.X (Addr 15.17.184.30)
Flags: vers=2,proto=udp,auth=unix,hard,intr,dynamic,devs,rsize=8192,
wsize=8192,retrans=5

/bogus from NFSserver11.X (Addr 15.17.187.90)
Flags: vers=3,proto=udp,auth=unix,hard,intr,link,symlink,devs,
rsize=8192,wsize=8192,retrans=5


A common question is "Ok, I know my NFS mount on the client is version 2; how
do I know what version of NFS is running on the server?"

On the NFS server, the command rpcinfo -p|egrep "service|nfs"
displays the NFS version.

root@NFSserver> rpcinfo -p |egrep "service|nfs"
program vers proto port service
100003 2 udp 2049 nfs
100003 3 udp 2049 nfs


This is a partial table for rpcbind(portmapper). As you can see, the service
NFS has two versions registered with rpcbind version 2 and version 3. NFS
client and server must both have version 3 registered to mount NFS V3.
A NFS V3 client will, by default, attempt to mount NFS V3; if the rpcbind
request receives an "accept status" of PROG_MISMATCH(meaning the NFS server
does not support NFS V3), the NFS client falls back and attempts a NFS V2 mount
