Goal

This document describes a common infrastructure configuration issue which may occur in networked enviornments when server communication is dependent upon the ability of the hosts to identify and resolve host names within the domain.

In distributed Oracle Secure Backup environnents, hosts must be able to communicate over the network.  Host communication can usually be tested using an operating system "ping" command.  Environments which have multiple network interfaces, may choose to configure OSB Preferred Network Interface (PNI) on the media server to define which network interface should be leveraged when communicating with another host(s) within the domain. 

OSB PNI's are commonly configured in Exadata environments so backup data over an Infiniband (IB) connection to the tape devices attached to a media server(s) and OSB control messages travel over a management (IP) connection to the OSB Administrative Server.  What about backing up the Administrative Server to tape devices attached to the media servers?  Backup of the Adminstrative Server would go over the management network while backup of Exadata nodes would go over the IB network.

What if the Exadata nodes can be successfully backed up to tape although their seems to be a communication problem between the OSB Administrative Server and media server for backing up the admin server?
