You can display a history of previous run levels using the fwtmp command.

Note: The bosext2.acct.obj code must be installed on your system to use this command.
  1. Log in as root user.
  2. Type the following at a command prompt: 
    /usr/lib/acct/fwtmp </var/adm/wtmp |grep run-level
    The system displays information similar to the following:
