Using OFM
This topic contains information on using OFM.
Initial deployment
Follow these steps for an initial deployment.
1. Update the firmware of the AMM, blade service processor, blade BIOSes and
2. Create an initial configuration file. See "Creating a configuration file
3. Download and store the new configuration file in a safe location. This file is the
4. Update the configuration file, if required, and save the resulting file.
5. Create a requirements report. Validate that you can apply the OFM
6. Apply the OFM configuration. See "Applying a new configuration" on page 20.
Adding a new chassis to the domain
When you need to add a new chassis to the domain, you will need to add its OFM
configuration to the OFM configuration file. You can either do it manually or use
the generate feature to create a new configuration file. In that case, you will need
to define the ranges so that they do not contain addresses that are already used by
the current configuration.
1. Create a file where each line contains the IP address or hostname of the new
2. Create a new configuration file using the list you just created.
3. After creating the new file, you can append it to the current file using a
4. Apply the configuration.
When you apply the combined file, only the changes to the new chassis are
applied assuming that for the other chassis the configuration in the file matches
the existing configuration.

configuration without errors. You can apply the configuration successfully even
if no blades are present or if the blade's firmware does not support OFM. In
this case, the AMM stores the configuration on the AMM and it will push it to
the blade when it is inserted or when its firmware is updated. See "Creating a
requirements report" on page 19.
