Configure serial console on Sunfire x86 machine with Oracle Linux 5.x and 6.x and Solaris 10u1 and later

Solution

ILOM Serial Port Configuration:

https://docs.oracle.com/cd/E19245-01/821-0489-13/ilom30_supplement.html#50610189_89135

Start Console:

From Ilom:

-> start /SP/console

From Elom:

-> start /SP/AgentInfo/Console

BIOS (Default):

https://docs.oracle.com/cd/E23393_01/html/E27229/z400012a1446073.html

Solaris 10u1 to Solaris 10u11 and Solaris 11:

<Document: 1012953.1>, <Document: 1018638.1>, and <Document: 1533902.1>

UFS:

For Solaris with UFS root the menu.lst is located in /boot/grub

ZFS:

For Solaris with ZFS root the menu.lst is located in the /<root pool>/boot/grub/

(ZFS example: /rpool/boot/grub/menu.lst)

Edit/verify the grub configuration:

menu.lst :

# Uncomment 'serial --unit=0 --speed=9600' and 'terminal serial'

serial --unit=0 --speed=9600

terminal serial

# comment out the "splashimage" line

#splashimage /boot/grub/splash.xpm.gz

-------------

From Solaris:

list eeprom parameters

# eeprom

# eeprom console=ttya

# eeprom ttya-mode=9600,8,n,1,-

(Ref: /boot/solaris/bootenv.rc)

Solaris 11.1 (GRUB2):

https://docs.oracle.com/cd/E26502_01/html/E28983/gkvhz.html#glzaj

bootadm set-menu console=serial serial_params=port[,speed[,data bits[,parity[,stop bits]]]]

# bootadm list-menu

# bootadm set-menu console=serial

Linux GRUB:

https://docs.oracle.com/cd/E20815_01/html/E20821/gjoxs.html

Edit the /boot/grub/grub.conf (/boot/grub/menu.lst is a soft link to grub.conf).

# Remove splashimage

#splashimage=(hd0,0)/grub/splash.xpm.gz

# Add

serial --unit=0 --speed=9600 --word=8 --parity=no --stop=1 -------> new line

terminal --timeout=10 serial console -------> new line

# add console=ttyS0,9600

kernel /vmlinuz-2.6.X.X ro root=/dev/XX/XX console=tty1 console=ttyS0,9600

Oracle Linux 5.x:

Add ttyS0 to /etc/securetty:

ttyS0

edit /etc/inittab

#Serial Port

s0:12345:respawn:/sbin/agetty -L 9600 ttyS0

Oracle Linux 6.x:

Add ttyS0 to /etc/securetty:

ttyS0

Additional note:

How To Enable Serial Console Support In OVM Server and access it via Ethernet (Doc ID 1624136.1)

Linux grub2:

Oracle Linux 7.x

Add the following GRUB lines to /etc/default/grub

GRUB_CMDLINE_LINUX='console=tty0 console=ttyS0,9600n8'

GRUB_TERMINAL=serial

GRUB_SERIAL_COMMAND="serial --speed=9600 --unit=0 --word=8 --parity=no --stop=1"

Re-generate GRUB configuration

Take a copy of the current grub.cfg file

Generate the new grub.cfg:

# grub2-mkconfig -o /boot/grub2/grub.cfg

PS: for EFI activated machines the path is /boot/efi/EFI/redhat/grub.cfg
