14 – Configuring and Monitoring a Redundant Server System
308 R400
Dual Network Configuration
In a dual network configuration the servers are connected on two networks and
have two network cards as illustrated in the following figure.
Modifying the hosts File
The following procedures assume that:
•For hsserva the TCP/IP address for the first network card is 200.0.0.1 and for
the second network card the TCP/IP address is 200.0.1.1.
•For hsservb the TCP/IP address for the first network card is 200.0.0.2 and for
the second network card the TCP/IP address is 200.0.1.2.
To modify the hosts file:
1 Use a text editor to edit the hosts file on the primary and the backup
server. (Note: If you use Microsoft Notepad to edit the hosts files, you
need to remove the .txt file extension after you save the files.)
The hosts file is:
%SystemRoot%\system32\drivers\etc\hosts
For example:
c:\winnt\system32\drivers\etc\hosts
2 Add the following lines to the hosts file:
# First TCP/IP link of the primary
200.0.0.1 hsserva hsserva0
# First TCP/IP link of the backup
