Chapter 5. Using OFM and OFM-Advanced upgrade
This section contains information on using the two offerings: OFM and
OFM-Advanced upgrade
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
adapters. See “Upgrading firmware” on page 6.
2. Create an initial configuration file. See “Creating a configuration file
automatically” on page 15.
3. Download and store the new configuration file in a safe location. This file is the
source of your OFM configuration.
4. Update the configuration file, if required, and save the resulting file.
5. Create a requirements report. Validate that you can apply the OFM
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.
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
chassis that you wish to add to the domain.
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
spreadsheet or text editor.
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.
Replacing a blade in the same slot
When you replace a blade in a slot that is OFM enabled, the OFM parameters are
automatically applied to the new blade before it is given power permission. The
boot sequence is not part of the OFM configuration and it is not pushed
automatically.
