Firmware (Licensed Internal Code) fixes
This topic describes the following types of firmware (Licensed Internal Code) fixes:
򐂰 Server firmware:
Server firmware is the part of the Licensed Internal Code that enables hardware, such as
the service processor. Check for available server firmware fixes regularly, and download
and install the fixes if necessary. Depending on your service environment, you can
download, install, and manage your server firmware fixes using different interfaces and
methods, including the HMC or by using functions specific to your operating system.
However, if you have a 57x or 59x model server, that is managed by an HMC, you must
use the HMC to install server firmware fixes.
򐂰 Power subsystem firmware:
Power subsystem firmware is the part of the Licensed Internal Code that enables the
power subsystem hardware in the model 57x or 59x servers. You must use an HMC to
update or upgrade power subsystem firmware fixes.
򐂰 I/O adapter and device firmware fixes:
I/O adapter and device firmware is the part of the Licensed Internal Code that enables
hardware, such as Ethernet PCI adapters or disk drives.
i5/OS I/O adapter and device firmware PTFs for i5/OS partitions are ordered, packaged,
delivered, and installed as part of the Licensed Internal Code using the same processes
that apply to i5/OS PTFs. Regardless of whether you use an HMC to manage your server,
you use the usual i5/OS PTF installation functions on each logical partition to download
and install the I/O adapter and device firmware fixes.
Operating system fixes
To keep your partitions running smoothly, it is important that you install fixes for your
operating system code when fixes are available.
You can access fixes for your operating systems using the Fix Central Web site:
http://www.ibm.com/eserver/support/fixes/
From the Web site, follow these steps:
1. In the Server list, click the appropriate family. For example, iSeries family or pSeries
family.
2. In the Product or fix type list, click the operating system for which you want to get a fix.
Depending on your selections for Server and Product or fix type, you might see additional
lists from which you can select specific options.
3. Click Continue.
