Recovering a Hung System
If you cannot log into the Solaris Operating System, and typing the
break
command
from the LOM shell does not force control of the system back to the OpenBoot
PROM
ok
prompt, then the system has stopped responding.
In some circumstances the host watchdog detects that the Solaris Operating System
has stopped responding and automatically resets the system.
Assuming that the host watchdog has not been disabled (using the
setupsc
command), then the host watchdog causes an automatic reset of the system.
You can issue the
reset
command (default option is
-x
which causes an XIR to be
sent to the processors) from the
lom>
prompt. The
reset
command causes the
Solaris Operating System to be terminated.
Caution –
When the Solaris Operating System is terminated, data in memory might
not be flushed to disk. This could cause a loss or corruption of the application file
system data. Before the Solaris Operating System is terminated, this action requires
confirmation from you.
