Configuring CMC to Use Command Line Consoles 55
Configuring Linux for Server Serial Console Redirection During Boot
The following steps are specific to the Linux GRand Unified Bootloader
(GRUB). Similar changes would be necessary for using a different boot loader.
NOTE: When you configure the client VT100 emulation window, set the window or
application that is displaying the redirected console to 25 rows x 80 columns to
ensure proper text display; otherwise, 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 two
new lines:
serial --unit=1 --speed=57600
terminal --timeout=10 serial
2
Append two options to the kernel line:
kernel............. console=ttyS1,57600
3
If the /etc/grub.conf contains a splashimage directive, comment it out.
The following example 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
timeout=10
#splashimage=(hd0,2)/grub/splash.xpm.gz
serial --unit=1 --speed=57600
