Branches down. Any ideas?

It started out 2 days ago with one printer down.  It would never work,
so I varied off everybody at the branch (ended the other printer first),
varied off the controller, and had them power everything off.

After powering back up (printers then terminals then controller) they
had only 2 terminals working and no printers.

We went through the controller config and it looked OK.  At some point,
there was "Internal object is damaged" and one of the suggestions is to
IPL.  I first tried deleted all devices related to that branch, but no
go.

So we powered down/up last night.

Now 5 branches are down!

They are all connected on frame relay using SNA on the ethernet line. 
There are other branches on ethernet that ARE working.  The routers are
Motorola and are apparently doing some kind of 5494 emulation. 
Controllers are IBM (don't know the model.)

APPC controllers, APPC devices, RWS controllers all say ACTIVE.  All
devices at these branches are VARY ON PENDING.

The router people say everything looks good and there should be signon
displays.  Nope.

Any thoughts?

TIA!
