(1) Host A with IPMI BMC installed:
a) BIOS POST:
(i) Enable "Console Redirection" in BIOS Setup.
For example, COM2 / 19.2Kbps / 8N1
(ii) Disable "Enable Console Redirection after POST" in BIOS setup.
b) BOOT LOADER:
(i) For GRUB, add the following TWO lines into /boot/grub/grub.conf, but comment out "splashimage=(hd0,0)/grub/splash.xpm.gz"
- Code: Select all
serial --unit=1 --speed=19200 --word=8 --parity=no --stop=1
terminal --timeout=10 serial console
#splashimage=(hd0,0)/grub/splash.xpm.gz
(ii) Then add "serial console=ttyS1,19200n8" to the end of kernel /vmlinuz in /boot/grub/grub.conf.
For example:
- Code: Select all
kernel /vmlinuz-2.6.5-1.358smp ro root=LABEL=/ rhgb quiet serial console=ttyS1,19200n8
This will result all boot message to be output to console ttyS1, and you will not see
all these boot messages in local console until login message promt up.
c) LINUX OS:
(i) Add the following line into /etc/inittab.
- Code: Select all
s0:2345:respawn:/sbin/agetty ttyS1 19200
(ii) Edit /etc/securetty and add ttyS1
(2) Host B with IPMIView installed:
a) Install and run IPMIView.
b) Log in Host A with IPMI BMC installed as Admin.
c) Start Console Redirection in IPMIView right after the Host A reboots.
You will see the BIOS POST, the boot loader, and the Linux OS messages and
prompts.
