4.0.0 HP Polyserve Matrix Server Administration Guide (T5392-96052, March 2010)

• When planning the virtual hosts needed for your cluster, first determine the network
services that will be available to your clients. Then determine the IP addresses for
those services. You will need to create a virtual host for each IP address.
• Choose virtual hostnames that differ from your actual server names. Virtual hosts
are independent of specific servers, and their names should be independent as
well.
• Use an IP address that is on the same subnet as the network interfaces where it
will be configured. The IP address must be higher than the system's primary ad-
dress.
• Update the hosts file (%SystemRoot%\system32\drivers\etc\hosts)
or the DNS name service with the virtual hostnames and IP addresses. (For im-
proved performance, the Management Console caches hostname lookups. If your
DNS changes, you may need to restart the console so that it will reflect the new
hostname.)
• Do not manually configure the IP address in the operating system or a system
startup script. Matrix Server configures the operating system appropriately to
support the virtual host.
• After creating virtual hosts, you will need to configure your applications to recog-
nize them.
Add or modify a virtual host
To add or update a virtual host, select the appropriate option:
• To add a new virtual host, select Matrix > Add > Add Virtual Host or click the V-
Host icon on the toolbar. Then configure the virtual host on the Add Virtual Host
window.
• To update an existing virtual host, select that virtual host on either the Server or
Virtual Hosts window, right-click, and select Properties. Then make your changes
on the Virtual Host Properties window.
