Thanks, Raj, that's interesting.
Perhaps I'll do some sort of discrepancy report to highlight any
differences.

Subject: Re: Implementing DNS on SP2
Fair enough point about forgetting to make changes to both environments. We
have just made it an admin responsibility and procedure that the hosts file
must have all AIX servers defined in it.
We have found in our testing that if DNS is down it takes a while before it
fails over and resolves to the secondary server, and because all our mission
critical apps are on the SP or on AIX servers we need to use local
resolution first. That way we have no real dependency for our applications
if DNS is down.
I guess you have to make a choice for netsvc.conf that is applicable to the
environment that you are working in. As I said for us and our applications
we find it more efficient to use local before bind.

Regarding netsvc.conf, I'm in two minds.
If one is going to use DNS, then surely it makes sense to _use_ it and use
"bind,local". Otherwise, if you omit to make a change in /etc/hosts as well
as DNS you could go badly awry.
If I really can cut /etc/hosts down to the bone that's not very likely to be
a problem, but we'll still have six distinct SP2s at the moment and over 100
nodes, in a fairly fluid environment. (We're doing a lot of consolidation at
the moment, so we keep moving things around and setting up temporary staging
systems etc.)
