|
|
.Sh DESCRIPTION
|
|
When the
|
|
.Nx Ns Tn /alpha
|
|
kernel is booted normally
|
|
it initializes itself and proceeds to start the system. An automatic
|
|
consistency check of the file systems takes place, and unless this
|
|
fails, the system comes up to multi-user operation. The proper way
|
|
to shut the system down is with the
|
|
.Xr shutdown 8
|
|
command.
|
|
.Pp
|
|
If the system crashes, it will enter the kernel debugger,
|
|
.Xr ddb 8 ,
|
|
if it is configured in the kernel.
|
|
If the crash occurred during
|
|
initialization and the debugger is not present or is exited, the
|
|
kernel will halt the system.
|
|
If the crash occurred during normal operation and the debugger
|
|
is not present or is exited, the system will attempt a dump to the
|
|
configured dump device (which will be automatically recovered with
|
|
.Xr savecore 8
|
|
during the next boot cycle), and after the dump is complete (successful
|
|
or not) the kernel will attempt a reboot.

|
|
The device names used by
|
|
.Nx Ns Tn /alpha
|
|
and the
|
|
.Tn SRM Console
|
|
often have no relation to each other.
