Sun Microsystems Sun SPARC Enterprise M4000 - Sending a Break Signal to a Domain

Chapter 4 Operation of the Server 4-19
3. Use the showdomainstatus(8) command to check the power status of the
domain specified to be reset.
Note – When the mode switch on the operator panel is set to "Service" or auto boot
is disabled by the setdomainmode(8) command, automatic boot of the Solaris OS
after the reset instruction is suppressed.
Note – Since the reset(8) command forcibly resets the system, this command may
cause a failure in a hard disk drive or other components. Use this command only for
the purpose of recovery, such as if the Solaris OS hangs, and for other limited
purposes.
