Table 2. Error messages
Message	Description
CPA3DE6	Cause: Software agreements were not found on the volume loaded in the alternate IPL device. Recovery: Read the instructions for the message that is displayed on the console. Perform the recovery action described in the message to correct the problem.
CPZ2003 CPZ2004 CPZ2005 CPZ2010 CPZ2011	Cause: The installation process received a tape or optical media error code. Note: If you are performing a network installation of the operating system, there is a network problem or slow network performance. Recovery for Error Code Ex10 0019 or Ex10 001A: Clean the media. If you are using tape, clean the tape head and tape path thoroughly. If you are using optical media, clean the media with a clean lint-free cloth. Gently wipe the disc from the center to the outside of the disc. Try the installation process again. If you were using the automatic installation process, go to Starting the automatic installation process again. If you were using the manual installation process, go to step 3 in Licensed Internal Code recovery to start the installation process again. If you receive another error message indicating a media error on the same installation media, contact your software provider to get another set of installation media to complete the installation process. Recovery for all other error codes: Contact your authorized service provider.
CPZ2022	Cause: The restore options read from the installation profile are not valid. Note: If you create distribution media and specify NONE for the installation profile name, the media will contain an empty installation profile. These media cannot be used to perform an automatic installation. Recovery:* Record the recovery information for the error message. Try to install the operating system again using the manual installation process. You can also try to use the automatic installation process with a different set of media. If the problem occurs again during an automatic installation process, contact your next level of service.
CPZ2023	Cause: The installation options read from the installation profile are not compatible with the current state of the system. The installation requested by the options read from the installation profile cannot be performed. For example, this condition can occur when an installation is requested that does not load program objects and that results in the QSYS library being damaged. Recovery: Try to install the operating system again using the manual installation process.
CPZ20xx	Cause: These termination messages are displayed by the installation of the operating system process. Print the display if possible; otherwise, copy all of the information. Recovery: Read the instructions for the messages that are displayed on the console. Perform the recovery action described in the message to correct the problem and then try the installation process again. Note: A short time after you press Enter, a B900 xxxx reference code is displayed. Analyzing and handling problems contains additional information.
