AIX 4.3: nfs mount: operation not permitted

We have a lot of different servers (Linux, HP, Sun, AIX 4, AIX 5, AIX
6). On all of these machines I could mount a nfs share, but not on our
AIX 4.3 machine. I get
<server name>:<directory>
vmount: Operation not permitted.
Curious: From the same nfs server I can mount another nfs share with the
same configuration without any problem. The shares are configured equal
on the nfs server.
/<directory>
dev = /<directory>
vfs = nfs
nodename = <server name>
mount = true
options = rw,hard,intr,rsize=8192,wsize=8192
account = false
The mount point does exist and has permission 755.
Any hints what to do?
Thanks in advance!

Hello,

may be you could check /etc/vfs and an check the permissions / existance
of the nfs mount helper mentioned therein.

I just got no such old AIX release anymore but to show an example for a
more recent release of AIX:

[***@system:/root] grep ^nfs /etc/vfs
nfs 2 /sbin/helpers/nfsmnthelp none remote
nfs3 18 /sbin/helpers/nfsmnthelp none remote
nfsv3 18 /sbin/helpers/nfsmnthelp none remote
nfs4 35 /sbin/helpers/nfsmnthelp none remote

[***@system:/root] ls -l /sbin/helpers/nfsmnthelp
-r-xr-xr-x 1 root system 43730 Dec 10 2013
/sbin/helpers/nfsmnthelp
[***@system:/root]
