HP Integrated Lights-Out 3 - Manual (Page 129)

After Linux is fully booted, a login console can be redirected to the serial port.
•
If configured, the /dev/ttyS0 and /dev/ttyS1 devices enable you to obtain serial TTY
sessions through the iLO Virtual Serial Port. To begin a shell session on a configured serial
port, add the following line to the /etc/inittab file to start the login process automatically
during system boot.
The following example initiates the login console on /dev/ttyS0:
S0:2345:respawn:/sbin/agetty 115200 ttyS0 vt100
The following example initiates the login console on dev/ttys1:
S1:2345:respawn:/sbin/agetty 115200 ttyS1 vt100
•
Use SSH to connect to iLO, and then use the iLO CLP command start
/system1/oemhp_vsp1
to view a login session to the Linux operating system.
Configuring the iLO Virtual Serial Port for the Windows EMS Console
iLO enables you to use the Windows EMS Console over the network through a web browser. EMS
enables you to perform emergency management services when video, device drivers, or other
operating system features prevent normal operation and normal corrective actions from being
performed.
When using the Windows EMS Console with iLO, note the following:
•
You must configure the Windows EMS console within the operating system before you can
use the iLO Virtual Serial Port. For information about how to enable the EMS console, see
your operating system documentation. If the EMS console is not enabled in the operating
system, iLO displays an error message when you try to access the iLO Virtual Serial Port.
•
The Windows EMS serial port must be enabled through the host system RBSU. The configuration
allows you to enable or disable the EMS port, and select the COM port. iLO automatically
detects whether the EMS port is enabled or disabled, and detects the selection of the COM
port. For more information about enabling the Windows EMS serial port, see
“Configuring
the iLO Virtual Serial Port in the host system RBSU” (page 125) .
•
You can use the Windows EMS Console and the iLO Remote Console at the same time.
•
To display the SAC> prompt, you might have to press Enter after connecting through the iLO
Virtual Serial Port.
To configure Windows for use with the iLO Virtual Serial Port:
1.
Open a command window.
2. Enter the following command to edit the boot configuration data:
bcdedit /ems on
3. Enter the following command to configure the EMSPORT and EMSBAUDRATE values:
bcdedit /emssettings EMSPORT:1 EMSBAUDRATE:115200
NOTE: EMSPORT:1 is COM1, and EMSPORT:2 is COM2.
Enter bcdedit /? for syntax help.
4. Reboot the operating system.
Using the Text-based Remote Console (Textcons)
You can access the Text-based Remote Console (Textcons) using a licensed iLO system and SSH.
When you use SSH, the data stream, including authentication credentials, is protected by the
encryption method that the SSH client and iLO use.
NOTE: For more information about iLO licensing, see the following website: http://www.hp.com/
