Chapter 24. Troubleshooting Installation on IBM System z

This section discusses some common installation problems and their solutions.
For debugging purposes, anaconda logs installation actions into files in the /tmp directory. These files include:
general anaconda messages
all external programs run by anaconda
extensive storage module information
yum package installation messages
hardware-related system messages
If the installation fails, the messages from these files are consolidated into /tmp/anaconda-tb-identifier, where identifier is a random string.
All of the files above reside in the installer's ramdisk and are thus volatile. To make a permanent copy, copy those files to another system on the network using scp on the installation image (not the other way round).

24.1.1. Is Your System Displaying Signal 11 Errors?

A signal 11 error, commonly known as a segmentation fault, means that the program accessed a memory location that was not assigned to it. A signal 11 error may be due to a bug in one of the software programs that is installed, or faulty hardware.
Ensure that you have the latest installation updates and images from Red Hat. Review the online errata to see if newer versions are available.
