enabling the Diagnostics mode.
In addition, you can emulate Stop-D function using the ALOM system controller
bootmode diag command. For more information, see the Sun Advanced Lights Out

About Automatic System Restoration
The system provides automatic system restoration (ASR) from failures in memory
modules or PCI cards.
Automatic system restoration functionality enables the system to resume operation
after experiencing certain nonfatal hardware faults or failures. When ASR is enabled,
the system’s firmware diagnostics automatically detect failed hardware components.
An autoconfiguring capability designed into the OpenBoot firmware enables the
system to unconfigure failed components and to restore system operation. As long
as the system is capable of operating without the failed component, the ASR features
enable the system to reboot automatically, without operator intervention.
For more information about ASR, see “About Automatic System Restoration” on
page 195.
