■
To clear the
fault.security.integrity-compromised@/sys/sp
fault,
replace the server’s top cover and either reboot the server’s SP or remove the AC
power cords, and then reconnect the cords.
■
To clear DIMM, CPU, motherboard, and PCIe faults, access the server’s ILOM SP
and clear the fault for the failed component. For information on how to use the
ILOM web interface or the CLI to clear server faults, see the
Sun Integrated Lights
Out Manager 2.0 User’s Guide
(820-1188).
Server Chassis Intrusion Sensors
The server has two sensors—the
/SYS/INTSW
sensor and the
/SYS/SP/SP_NEEDS_REBOOT
sensor—that are asserted when the server’s top cover
is removed while power is being applied to the server. This is an improper service
action so these sensors serve to alert you to any unauthorized and inadvertent
removal of the servers’s cover. Thus, these sensors enable system administrators to
have confidence that the physical integrity of the server has not been violated. This
is particularly beneficial when the server is in a remote or uncontrolled location.
How the
/SYS/INTSW
Sensor Works
The
/SYS/INTSW
sensor is asserted when the chassis intrusion switch trips while
the server is powered on. If the AC power cords are connected to the server, power
is being applied to the server. Even when you shut down the server’s host, power is
still being applied to the server. The only way to remove power from the server
completely is to disconnect the server’s AC power cords.
The chassis intrusion switch will trip if the server’s cover has been removed, the
switch itself is misaligned, or the cover is not properly seated. This sensor is de-
asserted when the integrity of the server’s chassis is restored, that is, when the
removed cover is properly reinstalled returning the chassis intrusion switch to its
closed state.
Caution –
Removing the server’s top cover while the power cord is connected to
the system is not an authorized service action. Proper service action requires that
host and SP shutdown operations be observed and that the power cord be
disconnected from the system before the cover is opened. If proper service actions
are taken, you should not see either the
/SYS/INTSW
or
/SYS/SP/SP_NEEDS_REBOOT
sensors asserted unless there are other issues, such as
a misaligned chassis intrusion switch.
