An overview of the preparation tasks that you can perform on your servers to ensure a successful install, which includes determining if there are any special instructions.
Determine how to install your fixes. Some fixes can be applied without requiring an IPL. These fixes are called immediate fixes. Some fixes can be applied only during an IPL. These are called delayed fixes. Immediate fixes can also be applied during an IPL. You need to determine if you are installing any delayed fixes and when it is convenient for you to IPL your system to apply the fixes. The cover letter tells you if the fix is immediate or delayed.
Before you begin to install fixes, complete these tasks:
- Have a current backup of your user data, operating system, and licensed programs. If you have backed up the operating system and licensed programs since the last time you applied fixes, that backup is acceptable.
- Have all users sign off the system only if you are doing an IPL when you install the fix.
For 8xx models, before applying a fix to the primary partition
of a system with logical partitions, power down the secondary partitions.
See Install fixes on systems with logical partitions for
further information. For eServer™ 5xx models, see the Customer service, support, and troubleshooting and
the Install fixes on systems managed by Hardware Management Console topics.
- Be sure you have security officer (*SECOFR) user class authority. You need it to do the rest of the install steps.
- Verify that your system is running on the B storage area. See the Determine the storage area topic for more information. Your server maintains two copies of all Licensed Internal Code: a permanent copy and a temporary copy. Read this topic to learn about the available storage areas.
