Chapter 9: HeartBeat 
This section describes the high availability Linux application called “HeartBeat” in more detail. 
The automated installation script creates all the defaults covered in this chapter.
How HeartBeat Works
You can configure the Avaya IP Telephone File Server Application in a high availability mode 
using two servers. The application uses a combination of the HeartBeat High Availability Linux 
software and the RSync utility.
HeartBeat allows two servers to monitor the health of each other over a private Ethernet or 
serial link. HeartBeat manages a single, publicly available IP address for the Avaya IP 
Telephone File Server Application server to share. RSync is a sophisticated file comparison/
duplication utility. In this case, RSync mirrors the data files between the two servers.
Note:
Note:
To control a High Availability cluster you only use the HeartBeat daemon control. 
Do not manually start or stop the Avaya IP Telephone File Server Application or 
MV_WatchDog daemons. HeartBeat does this for you as needed.
The fundamental requirements are:
two identical Intel-based servers with dual Ethernet connections.
RedHat Linux Enterprise Server Version 3, Update 4 0r 5. 
Avaya IP Telephone File Server Application server software.
HeartBeat software, available at

RSync software, available at

Note:
The MV_IPTel_Install.sh is a self-extracting script which contains all the 
components needed beyond the Red Hat OS installation.
