I get this error both thru NIM creating a resource and manually on the client with the export FS mounted.

Any help is greatly appreciated. Or point me in the right direction.
Thanks.

We used to receive this type of error on our servers with two IP Addresses and host names. They were servers we used to have HACMP configured on. The problem NIM has with it is that communication may come into the server on one IP/Hostname, but go out on another.

I can see why you may have gotten that error with HACMP. We run HACMP but not on this box. I think this is really an NFS security issue. I'm not sure why since I am taking the defaults. I've tried changing the 1st method to "none" but that doesn't work either.

Anyone have any suggestions?

NIM is only nfs v3 capable.

If you create the NFS share with smit then it uses NFS v4 and adds the security stanza which confuses NIM.

Create the share with nim, or the command line and don't specify the security at all.

Can I just edit the exports file to do this?

You're the man.
Thanks again.

Just one more thing I was curious about. I hit the mouse too soon.

Was this error really preventing a full mksysb from taking place or was it just a warning type error but the mksysb really was successful?
You know what I mean?

From the messages I suspect the mksysb would have been OK:
0512-038 savevg: Backup Completed Successfully.
But you would likely have a problem if you tried to deploy it with NIM because of the sec stanza in the nfs share.

This is just a guess though.

Don't worry about it, it's not an "error" in the sense that something bad is
happening. All it means is that NIM doesn't support an NFS security option.
This reporting of totally un-usefull information has been a bug in NIM from the
early days.
The short version is: Ignore it.

Yeah, that's what I was thinking since I see this occassionally in other parts of AIX. The bogus/extraneous error messages that is.
But I'm new to NIM so just wanted to confirm.
That's good to know.
Thanks guys.
