Configuring Linux 6 to use the iLO Virtual Serial Port
Procedure
1. Configure GRUB based on the following configuration examples.
NOTE:
In the following configuration examples, ttyS0 and unit 0 are for com1 and ttyS1 and unit 1
are for com2.
The following configuration example uses Red Hat Enterprise Linux 6 and com1:
serial -unit=0 -speed=115200 terminal -timeout=10 serial console
default=0
timeout=10
#splashimage=(hd0,2)/grub/splash.xpm.gz title Red Hat Linux (2. 6.18-
164.e15) root (hd0,2)
9
kernel /vmlinux-2.6.18-164.e15 ro root=/dev/sda9 console=tty0
console=ttyS0,115200
initrd /initrd-2.6.18-164.e15.img
If com2 was selected, the configuration example would be as follows:
serial -unit=1 -speed=115200 terminal -timeout=10 serial console
default=0
timeout=10
#splashimage=(hd0,2)/grub/splash.xpm.gz title Red Hat Linux (2. 6.18-
164.e15) root (hd0,2)
9
kernel /vmlinux-2.6.18-164.e15 ro root=/dev/sda9 console=tty0
console=ttyS1,115200
initrd /initrd-2.6.18-164.e15.img
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.
2. 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
3. Use SSH to connect to iLO, and then use the iLO CLP command start
/system1/oemNEC_vsp1 to view a login session to the Linux operating system.
