The HWdiag utility checks the status of a system and its
components. You run the HWdiag utility within the Oracle ILOM
Diag shell.
|
Can function on Standby power and when operating system is not
running.
|
Local, but remote serial access is possible if the SP serial
port is connected to a network-accessible terminal
server.
