errors are occurring. If there are any errors, the dlmchpdattr utility
might end with an error.
• If you cancel the execution of the dlmchpdattr utility by pressing Ctrl +
C, the KAPL10571-I message might be output depending on the timing of
the cancellation. This message signifies that the setting change was not
successful. If this message is output, re-execute the dlmchpdattr utility

and then execute the dlmchpdattr utility with the original parameters
specified.
