HDLM outputs the log information for analyzing errors at the time of
installation to a file. The file name, which is the output destination, is /
var/tmp/hdlminstlog/installhdlm[01-10].log, and the maximum
number of files that can be created is 10. If 10 files already exist and you
perform another installation, the oldest file is deleted and a new log file is
output.
