Chapter 4. Configuring BladeCenter Open Fabric Manager
Configuring OFM involves a number of steps that include the creation of your
configuration file and applying the new configuration, along with several other
considerations.
Important: You must configure OFM through the AMM Web interface before you
Creating a configuration file automatically
When using OFM for the first time, you will need to create a configuration file in
which you assign virtual addresses to each slot in each chassis.
The following example outlines the kind of steps you might follow when creating
a configuration file automatically. It does not apply to all BladeCenter
environments. These example steps assume that you have a single domain (no
addresses are duplicated).

Note: You also have an option here to specify a value in the LUN field.
7. Click Next. This will open the Chassis to include page in the right pane.
8. On the Chassis to include page, there are two methods for providing the list
of chassis to be included in the configuration file.
You can either create a file with the list of AMM IP addresses or use the
chassis that were discovered by the AMM via SLP. When using the Use AMM
IP Addresses that were discovered on the AMM management network
button, you should verify that all the chassis that you want to configure OFM
on are listed on that page When using the AMM via SLP method, all of the
chassis that were discovered will be displayed on the AMM Web interface
Remote Chassis page.
If you elect to use an explicit list of AMM IP addresses instead, create a text
file in which each line contains a single IP address or the hostname of a single
chassis. If you use hostnames in this file, you will need to enable DNS and
define at least one DNS server on the AMM Web interface Network Protocols
page. When the text file is complete, you can then select the Use AMM IP
