- The procedures that are documented for merging networks assume that
- you want to preserve the user base from the old environment. This
- appears to not be the case for you. In general what you have done
- (killing the glbd and rgyd for the now defunct network) should be
- enough. If the machines do not find the new registry (the registry
- on //car, then it is probably because either one or the other or
- both of the previously independent networks were running as unique
- glbd "cells".
-
- Normally all Domain/OS machines look for a glbd running with a
- well known universal unique identifier (UUID). If you want to run
- multiple "logically independent" domain networks on a common physical
- network, it becomes necessary to introduce a per-logical network UUID
- for each glbd. This is stored in the file /etc/ncs/glb_obj.txt on each
- machine of the logical network.
-
- You should check your machines and verify that //res //ind and //cap contain
- a file that is identical with the glb_obj.txt file on the rest of the
- machines (or none if the other machines did not have one).
