Updating the pe_site File
Whenever the master's or a slave's network address changes, you must update the /opt/dcelocal/etc/security/pe_site file on that host before restarting secd. This file, which exists on each machine in the cell, is required for binding by the DCE Security Service to itself. For the master replica, the file contains the cell name and the name of the master. For slave replicas, the file contains the cell name, the name of the master replica, and the name of the replica itself.
If the master replica address changes, update the pe_site file on every node in the cell that runs a security server (including the master) with the new address for the master. If a slave address changes, update only that slave's pe_site file to reflect its changed address.
