Receive server firmware fixes using an HMC
If you use an HMC to manage your server and you need to configure several partitions on the
server periodically, 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 two 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 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.
Receive server firmware fixes without an HMC
Periodically, you need to install fixes for your server firmware. If you do not use an HMC to
manage your server, you must get your fixes through your operating system. In this situation,
you can get server firmware fixes through the operating system regardless of whether your
operating system is AIX 5L or Linux.
To do this, complete the following tasks:
1. Determine the existing level of server firmware using the lsmcode command.
2. Determine the available levels of server firmware.
3. Get the server firmware.
4. Install the server firmware fix to the temporary side.
5. Verify that the server firmware fix installed successfully.
6. Install the server firmware fix permanently (optional).
