Chapter 7. Installing program temporary fixes on a system

with logical partitions

The basic steps of installing a program temporary fix (PTF) are the same on a system with logical

partitions as on a system without logical partitions. However there are some precautions you should take:

v When you load PTFs to a primary partition, power down all secondary partitions before you restart the

primary partition.

v When using the GO PTF command on the primary partition, change the automatic IPL parameter from

the default (*YES) to (*NO). You do not have to do this if you first power down the secondary partitions.

You can find information on installing PTFs in the Tips for Managing your System chapter of AS/400 Basic

System Operation, Administration, and Problem Handling

fixes with Management Central.

Installing Partition Sensitive PTFs

Most fixes pertaining to logical partitioning are applied as mentioned above. However, there are certain

partition sensitive PTFs that apply specifically to the lowest level code that controls logical partitions.

Partition specific PTFs will have special instructions referring to these steps.

Attention: Failure to follow these steps exactly could result in a lengthy recovery process.

For partition sensitive PTFs you should follow these steps exactly:

1. Permanently apply any PTFs superseded by the new PTFs.

2. Perform an initial program load (IPL) of all partitions from source A.

3. Load the PTFs on all logical partitions using the OS/400 load PTF (LODPTF) command. Do not use

the GO PTF command.

4. Apply the PTFs temporarily on all logical partitions using the OS/400 apply PTF (APYPTF).

5. Power down all secondary partitions.

6. Perform a power down and IPL of the primary partition from source B in normal mode.

7. Perform normal mode IPLs of all secondary partitions from source B.

8. Apply all of the PTFs permanently using APYPTF.
