Enabling IPMI on managed system
On a managed system, use the Dell Open Manage Server Administrator to enable or disable IPMI. For more information, see the
Dell Open

Configuring Linux for serial console during boot
The following steps are specific to the Linux GRand Unified Bootloader (GRUB). Similar changes are required if a different boot loader is
used.
NOTE:
When you configure the client VT100 emulation window, set the window or application that is displaying the
redirected Virtual Console to 25 rows x 80 columns to make sure the correct text displays. Else, some text screens may
be garbled.
Edit the
/etc/grub.conf
file as follows:
1.
Locate the General Setting sections in the file and add the following:
serial --unit=1 --speed=57600 terminal --timeout=10 serial
2.
Append two options to the kernel line:
kernel
.............
console=ttyS1,115200n8r console=tty1
3.
Disable GRUB's graphical interface and use the text-based interface. Else, the GRUB screen is not displayed in RAC Virtual Console.
To disable the graphical interface, comment-out the line starting with
splashimage
.
The following example provides a sample
/etc/grub.conf
file that shows the changes described in this procedure.
# grub.conf generated by anaconda
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that all
# kernel and initrd paths are relative to /, e.g.
# root (hd0,0)
# kernel /boot/vmlinuz-version ro root=/dev/sdal
# initrd /boot/initrd-version.img
#boot=/dev/sda
default=0
