Are you sure you want to start /SP/console (y/n)? y

It hangs at that point. Typing on the keyboard reflects nothing visually on the screen.

Also, trying to stop, start or reset the SP does not help.

Note : menu.lst is a working copy of the grub.conf. Please make sure they match.

Displaying kernel messages on one or more consoles

On each kernel line listed in /boot/grub/grub.conf and/or /etc/lilo.conf, append the correct "console" statement as a parameter to the kernel. The following is an example from grub.conf (my addition to the line appears in bold):

   kernel /vmlinuz-2.6.9-22.0.2.EL ro root=LABEL=/ console=tty1 console=ttyS0,9600

Provide a login prompt to the serial console

In /etc/inittab, below the 6 mingetty lines, add the following agetty line:

   S0:12345:respawn:/sbin/agetty 9600 ttyS0 vt100

Allow root to login via the serial console

To the end of /etc/securetty add the following line:

   ttyS0
