Linux

You must edit two files in Linux to ensure that the console redirection still works after the

operating system has loaded. The same files are changed for Red Hat Linux (RHEL) and

SUSE Linux.

Edit these files:

򐂰 /boot/grub/menu.lst

򐂰 /etc/inittab

Menu.lst or grub.conf

Add the parameter that is highlighted in bold in the file that is shown in Example 9-24.

Example 9-24 Example of the grub.conf

# grub.conf generated by anaconda

#

# Note that you do not have to rerun grub after making changes to this file

# NOTICE: You have a /boot partition. This means that

# all kernel and initrd paths are relative to /boot/, eg.

# root (hd0,1)

# kernel /vmlinuz-version ro root=/dev/mapper/VolGroup-lv_root

# initrd /initrd-[generic-]version.img

9.14.4 How to start a SoL connection

In this section, we explain how to connect to the HX5, x3850 X5, or x3690 X5 through SoL.

RHEL 6: If you have installed RHEL 6 in UEFI mode, you must edit the

/boot/efi/EFI/redhat/grub.conf file instead of the /boot/grub/menu.lst file.

534 IBM eX5 Implementation Guide

Connecting to the x3690 X5 or x3850 X5

You can use Telnet or SSH to connect to the x3690 X5 or x3850 X5 servers. Follow these

steps:

1. Start a Telnet/SSH session to the IMM IP address.

2. Log in to the IMM. The default user id is USERID and the default password is PASSW0RD,

where the 0 is a zero.

3. The IMM CLI main page appears (Figure 9-92).

Figure 9-92 IMM CLI main page

4. Start SoL with the console 1 command.

The SoL console starts and you see whatever is transmitted over the SoL connection (for

example, the UEFI setup windows). See “Sample output” for examples of what you see over

an SoL connection when the system boots.

Connecting to the HX5

You can use Telnet or SSH for the connection to the BladeCenter HX5. Follow these steps:

1. Start a Telnet/SSH session to the AMM IP address.

2. Log in to the AMM. The default user id is USERID and default password is PASSW0RD, where

the 0 is a zero.

3. The AMM CLI main page appears (Figure 9-93).

Figure 9-93 AMM CLI main page

4. Start SoL with the console -T system:blade[5] command.

The SoL console starts and you see whatever is transmitted over the SoL connection (for

example, the UEFI setup windows). See “Sample output” for examples of what you see over

an SoL connection when the system boots.

Sample output

After you connect to the system using SoL and power on the server, you see the output in the

telnet/SSH window. Figure 9-94 shows the x3850 X5 booting.
