Advanced Configuration of the DRAC 5 49
RAC Serial Interface
RAC also supports a serial console interface (or RAC Serial Console) that
provides a RAC CLI, which is not defined by IPMI. If your system includes a
RAC card with Serial Console enabled, the RAC card will override the IPMI
serial settings and display the RAC CLI serial interface.
To enable the RAC serial terminal interface, set the cfgSerialConsoleEnable
property to 1 (TRUE).
For example:
racadm config -g cfgSerial -o cfgSerialConsoleEnable 1
See "cfgSerialConsoleEnable (Read/Write)" for more information.
Table 4-1 provides the serial interface settings.
Configuring Linux for Serial Console Redirection During Boot
The following steps are specific to the Linux GRand Unified Bootloader (GRUB).
Similar changes would be necessary if you use 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
