Stop-F Functionality
The Stop-F functionality is not available on systems with USB keyboards.
Stop-D Functionality
The Stop-D (Diags) key sequence is not supported on systems with USB keyboards.
However, the Stop-D functionality can be closely emulated by setting the virtual
keyswitch to diag, using the ALOM setkeyswitch command.
Automatic System Recovery
The system provides for automatic system recovery (ASR) from failures in memory
modules or PCI cards.
Automatic system recovery functionality enables the system to resume operation
after experiencing certain nonfatal hardware faults or failures. When ASR is enabled,
the firmware diagnostics automatically detect failed hardware components. An
autoconfiguring capability designed into the system 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.
