Removing and rebuilding farm = reinstall?

  Asked By: Chaim    Date: Sep 19    Category: Sharepoint    Views: 5746

We're pretty close to giving up on our farm configuration of 3 FE
servers outside our firewall and one inside. It's appearing that this is
not a viable solution.

As such, I want to rebuild the farm with JUST the 3 FE servers, and
rebuild the DB. Short of reinstalling on every server, is there a way to
do this?

Right now Central Admin is on the inside server. I could 'disconnect'
the 3 outside servers, then delete the DBS, but then how would I
'reconnect' the 3 servers to a new farm/config DB?

Or should I just reinstall? (And now that I've thought about it, since
we don't have any 'real' content to restore, I'm thinking reinstalling
is probably the best method).

You can move the central  admin website by re-running the SharePoint
Products and Technologies Configuration Wizard. You can also use
Central admin  to remove specific servers  from the Farm (Operations
Tab>Servers in Farm. And you can move specific services to different
servers using the Operations Tab>Services on Servers entry.

it is not necessary to reinstall  everything just to
reorganize your farm.

In your scenario, I would pick the server  on which I want to run Central
Administration.

Run the Configuration Wizard again on that server and choose to run
Central Administration there.

Then on the server that you want to remove from the farm, you can either
run the Configuration Wizard and disjoin from the farm  or just uninstall
SharePoint.

Then, in Central Administration, Operations, Services on the Servers,
change the roles.

The service that you would want to avoid moving is the index server as
that requires rebuilding the complete index.

Since SharePoint does not track IP addresses, you can also just move the
servers from one subnet to another.

It is really easy to reattach the content  databases. Your site heirarchy
will put itself all back in to place. I'm not understanding why you need
a new farm  to move the WFE. Which machine runs central  admin? Inside or
outside the firewall?

You know, I must apologize. I've been getting used to the fact that
things are usually more complicated than they should be with most
aspects of MOSS, but this, indeed, was very easy. I ran the wizard,
disconnected the farms, and then deleted the DBs. Now I'm about to
rebuild the config DB and put it all back together.

As for why we're redoing it, since we had no real  data in the DBs yet,
we figured we might as well just start fresh.

The reason we're moving is that we can't get the inside  FE server
(running central admin) to talk to the outside servers. The issue is
that we need to open a variety of ports in the FW for the communication
to happen, but the ports that need to be opened aren't documented in any
detail anywhere by Microsoft, and our networking folks, understandably,
don't feel like shotgunning the firewall  randomly and opening it all up.
Spending a week on the phone with MS support was of no help, and a MS
Gold partner wasn't able to get us much further either.

So, we're going to just forgo the internal server  for now.

I guess it's of no interest to you now, but in case other people
have this issue, I think the ports used by SharePoint are fairly
comprehensively documented in Microsoft's planning information for
extranets (see http://technet2.microsoft.com/Office/en-
us/library/45086574-a9e9-42f2-a2f7-92fee6897f1c1033.mspx).
