On the server blade you are updating, issue the
fweupdate.efi
command from the EFI
command prompt by entering:
fweupdate.BL860c.sxxxx.byyyy.mzzzz.efi
.
where:
s
means system firmware;
xxxx
is the system firmware version number
b
means BMC firmware;
yyyy
is the BMC firmware version number
m
means iLO 2 MP firmware;
zzzz
is the iLO 2 MP firmware version number
This command updates the system firmware, BMC firmware, and iLO 2 MP firmware.
Troubleshooting the Server Interface (System Console)
All system console connections (local RS-232 and iLO 2 MP LAN) are made through the I/O port
connector on the front of the server blade, through the local I/O cable.
HP-UX uses the RS-232 serial text connection to a dumb terminal, or to terminal emulator software
running on a PC, to control server blade operations locally. All other connections are unsupported.
HP-UX alternatively uses the MP’s 10/100 BT LAN connection over a private network, to control
one or more server blade operations -- locally through telnet or Secure Shell (SSH), or remotely
over a public network through a web GUI.
NOTE:
RS-232 connection: If a dumb terminal/PC running terminal emulation software is attached
to the iLO 2 MP local port and does not respond to a
Ctrl-B
key sequence (and the terminal is
running 9600 baud, 8 data bits, is online, etc.) then it is possible that the iLO 2 MP is not
operational/functional.
Troubleshooting the Environment
Ambient intake air temperature is often different from ambient room temperature; measure the
operating temperature and humidity directly in front of the cabinet cooling air intakes, rather than
measure only ambient room conditions.
Within the server blade enclosure, temperature sensors report chassis temperature to the BMC.
The BMC controls fan speed, based on this information.
Temperature sensors are found on:
•
I/O baseboard, where the processors provide an integrated temperature sensor
•
Status panel, where a thermal sensor detects the ambient room temperature. This sensor’s
reading is the main parameter used to regulate fan speed, under normal conditions.
