Receive server firmware fixes using an HMC
If you use an HMC to manage your server and you periodically configure several partitions on
the server, you need to download and install fixes for your server and power subsystem
firmware.
How you get the fix depends on whether the HMC or server is connected to the Internet:
The HMC or server is connected to the Internet.
There are several repository locations from which you can download the fixes using the
HMC. For example, you can download the fixes from your service provider's Web site or
support system, from optical media that you order from your service provider, or from an
FTP server on which you previously placed the fixes.
Neither the HMC nor your server is connected to the Internet (server firmware only).
You need to download your new server firmware level to a CD-ROM media or FTP server.
For both of these options, you can use the interface on the HMC to install the firmware fix
(from one of the repository locations or from the optical media). The Change Internal Code
wizard on the HMC provides a step-by-step process for you to perform the procedure to install
the fix. Perform these steps:
1. Ensure that you have a connection to the service provider (if you have an Internet
connection from the HMC or server).
2. Determine the available levels of server and power subsystem firmware.
3. Create the optical media (if you do not have an Internet connection from the HMC or
server).
4. Use the Change Internal Code wizard to update your server and power subsystem
firmware.
5. Verify that the fix installed successfully.
