Command Description
help Displays the menu list.
restart_cpu Issues a broadcast interrupt (level 7) to all CPU boards in
the system and generates a system dump.
shutdown Initiates an immediate orderly system shutdown by
invoking the power down process specified for the
powerdown daemon in the /etc/inittab file. The
powerdown daemon must be running for this command to
work. For information about spawning the powerdown
daemon, see the powerdown(1M) man page.
reset_bus
If there is a nonbroken CPU/memory board in the system,
this command issues a “warm” reset (that is, save current
registers) to all boards on the main system bus. This
command immediately kills all system activities and reboots
the system. CAUTION: Do not use this command if you
want a system dump; use the hpmc_reset command
instead.
