The following progress codes (or checkpoints) represent various processes that occur during initial program load (IPL). The list of progress codes is in numeric order. A general description of the process represented by the progress code appears beside each number (or range of numbers). Progress codes are 8-characters long, unless otherwise specified.
For information about using this list of progress codes and about progress codes in general, see Using progress codes.
Use the following list to find information about specific progress codes. The first column represents the first 4 characters of the 8 character progress code, unless otherwise specified. The second column describes the progress code and links to information that includes one or more tables. If you do not find the progress code that you are looking for in this list, ask your next level of support for assistance.
