Auto-Boot Options; Error Handling Summary - Sun Microsystems Fire V240 Administration Manual

As long as a failed component is electrically dormant (not causing random bus
errors or signal noise, for example), the system will reboot automatically and resume
operation while a service call is made.
Note – ASR is not enabled until you activate it.

Auto-Boot Options

The auto-boot? setting controls whether or not the firmware automatically boots
the operating system after each reset. The default setting is true.
The auto-boot-on-error? setting controls whether the system will attempt a
degraded boot when a subsystem failure is detected. Both the auto-boot? and
auto-boot-on-error? settings must be set to true to enable an automatic
degraded boot.
To set the switches, type:
ok setenv auto-boot? true
ok setenv auto-boot-on-error? true
Note – The default setting for auto-boot-on-error? is false. Therefore, the
system will not attempt a degraded boot unless you change this setting to true. In
addition, the system will not attempt a degraded boot in response to any fatal non-
recoverable error, even if degraded booting is enabled. For examples of fatal non-
recoverable errors, see "Error Handling Summary" on page 82.

Error Handling Summary

Error handling during the power-on sequence falls into one of the following three
cases:
If no errors are detected by POST or OpenBoot Diagnostics, the system attempts
to boot if auto-boot? is true.
If only non-fatal errors are detected by POST or OpenBoot Diagnostics, the
system attempts to boot if auto-boot? is true and auto-boot-on-error? is
true.
