Handling Network Address Changes
When secd starts, master and slave replicas can detect address changes and can perform the necessary updates to the master's replica list and to the cell namespace. Generally, all that is required on your part to handle network address changes is to update the pe_site file. However, if the network address of the master and a slave replica change simultaneously, your intervention is required. This subtopic describes how to update the pe_site file and how to handle simultaneous address changes.
