Learn about ongoing fix support and upgrades for your server or HMC and how to obtain software and firmware fixes.
Periodically, a problem might be discovered in your server's software or firmware (Licensed Internal Code). When the service and support organization discovers a problem in your software, a software fix, sometimes referred to as a program temporary fix (PTF), is distributed. If a problem is discovered in the firmware, the fix might be released as a PTF or as a firmware fix, depending on the server type and model.
Fixes play an important part in your server's maintenance strategy. They give you a chance to reduce system downtime, add functionality, or provide optimal availability. It is important that you develop a fix-management strategy to help you keep track of code fixes that are available for your software and firmware.
For more details about how to download and install various types of fixes, see Fixes and upgrades.
