For NIM: NFS file system problem

UNIX AIX
1

hello,

i am trying to export a file system so that i can mount it on NIM server and make mksysb backup of the server on that fs.
i get this message:
mount: 1831-011 access denied for s_semdev:/dr_s_zeus/mksysb/dr_s_zeus
mount: 1831-008 giving up on:
s_semdev:/dr_s_zeus/mksysb/dr_s_zeus
The file access permissions do not allow the specified action.
Note that s_semdev is my NIM server and dr_s_zeus is the server that the file system is resides originally.
i search and i find various solutions about this but whatever i tried it failed.
in the mean time i noticed that the AIX versions of these 2 servers are different. The server that i exported the file system is AIX 5.3 and my NIM server (the server that i mount the exported fs) is AIX 6.1. Does this create any problem to my procedure?

Thank you for your time.

So if you started by explaining what you have done or tested so far, someone could maybe help

ok trying to summarize:
you tried to export a filesystem on s_semdev called /dr_s_zeus/mksysb/dr_s_zeus to the server dr_s_zeus ?
How did you export - public filesystem ? and did you explicitely allow root access to dr_s_zeus ?

ok this is what i have done...
on dr_s_zeus server i exported a file system /nim and from the characteristics of exported filesystems using smit i assign it to server s_semdev which is my NIM server.
on s_semdev i run the command: mount dr_s_zeus:/nim /dr_s_zeus. So i mounted the /nim filesystem of dr_s_zeus in the mountpoint /dr_s_zeus on s_semdev.
Then i tried to perform administration task using smit nim. i want to perform mksysb backup of dr_s_zeus from s_semdev and to assign it in the directory /dr_s_zeus/mksysb/dr_s_zeus/"resource_name".
At this time i get the message mentioned above.

You missed zxmaus important remark:

i exported the filesystem using the command mknfsexp -d /filesystem.
then using smit from Change / Show Attributes of an Exported Directory i assign my NIM server on Hosts & netgroups allowed client access and Hosts allowed root access fields.
