General opinion is, and I found it to be true is that auto.master is either
outdated or broken, and there is no point in messing with it.
However it is possible to run NIS and automounter on RS6000 clients.
Also many suggested badgering IBM for a fix.
Mark Miller suggested that I have a different set of maps for the RS6000
that are generated by the sun master. I didn't try that, but that seems like
it will work.
Walter Hartheimer's suggestion was the one I took.
I placed the mount points in /etc/rc.nfs on the RS6000 and created the
files /etc/auto.home auto.build etc with +auto.home and +auto.build in them.
The automount has to be invoked from the /etc/rc.nfs file as follows
/usr/etc/automount -m /home /etc/auto.home
The -m means don't refer to the NIS maps, thus it won't read auto.master.

Surprise, surprise..... The RS6000 has automount based of 4.0.0 not 4.0.3
or 4.1 or 4.1.1.... This means it is severely broken. No NIS maps, etc....
Sorry. I've already fried IBM over this one. The were advertising it as 4.0.3
based.

An RS6000 is a semi-UNIX machine which you can't expect to
work as well as any other real UNIX machine in a UNIX environment.

The options in auto.master are considered defaults for the auto.home
map, but can be overridden by entries in auto.home.
I have set up automount between RS6000 and Sun without any problems.
But i don't have any access to that setup anymore... I did it for a
customer.

Hello,
About your question on NIS/autmounter/and Suns and AIX machines. We
are doing the same thing, using a Sun NIS server for the AIX machines
using the automounter. Yes, the IBM and Sun automount maps are
somewhat different.
We solved the problem by distributing a complete separate set of maps
for the AIX machines. For example, we created auto.master2 for the AIX
machines, then fired up the AIX automounters with the command:
/usr/etc/automount -m `/usr/bin/ypcat -k auto.master2`
The -m says to ignore the auto.master map, and the ypcat fills in the
command line with the alternate master map. Any maps referenced in
that master map are then picked up by the automounter automatically
(even though this doesn't seem to be documented).
Actually, we had a lot of trouble with the AIX automounter, and ended
up using AMD on the AIX machines. For that we have another set of maps
called amd.master1, etc.

There is a fix to the IBM automounter that amoung other things enables it to
deal with unknown options more gracefully (unknown to the IBM at least). The
automounter that they supply is apparently a very very early one supplied by
Sun. Call them up to get a fix and to badger them to get the most recent
Sun automounter ported.

Subject: Re: NFS automounter on an RS6000 client with a sparc NIS server
My experience has shown that the auto.master does not work. I have placed the mount points
in the automount startup command in rc.nfs.
Note the line:
if [ -x /usr/etc/automount ]; then
/usr/etc/automount /home auto.home /vol auto.vol
fi
is the last line in my rc.nfs which gives me two mount points for the automounter.
rc.nfs is spawned by an entry in inittab
Note the line:
rcnfs:2:wait:/etc/rc.nfs > /dev/console 2>&1 # Start NFS Daemons
Hope this helps!

I would call IBM and ask for a fix. My understanding is that the
version of NFS/NIS that they are using is of SunOS 3.5 vintage, and
has a number of bugs. What version of AIX are you running? At least
3.1.5 I hope:-)
I hope this helps.

The 6000 uses the old Sun automounter from SunOS 4.0.3.
Someone in my group is working on porting the 4.1.1 automounter.
You might want to ask your IBM SE about this or call the Austin Support Center. There are fixes to automounter bugs.
Hope this helps.
