These procedures describe how to preconfigure your network running SLES 11 software to support PXE installation of SUSE Linux software on your Sun Fire X4140, X4240, or X4440 server. These procedures assume that you already have a bootable server that is running a version of the SLES 11 OS.

Preconfiguring your network for PXE installation involves the following procedures:

Copying Files From the Tools and Drivers CD

Configuring a DHCP Server

Installing Portmap

Configuring the TFTP Service

Configuring the NFS Service

Disabling the Firewall

Required Items

Preconfiguring your network for PXE installation requires the following items:

SLES 11 server equipped with:

CD/DVD drive

USB keyboard

Monitor (optional)

SLES 11 media set

Sun Fire X4140, X4240, or X4440 server Tools and Drivers CD

Caution - On the chassis, Ethernet ports are labeled NICi (i = 0,1,2,3). Linux internally represents Ethernet ports as ethj (j = 0,1,2,3). Labeling implies NICi -> ethj, where i=j. This is generally true, but for the for Sun Fire X4140, X4240, or X4440 servers the mapping is as follows:

NIC0 -> eth2
NIC1 -> eth3
NIC2 -> eth0
NIC3 -> eth1

Copying Files From the Tools and Drivers CD

This section describes how to copy the required PXE configuration support files, from the Sun Fire X4140, X4240, and X4440 server Tools and Drivers CD to the DHCP/PXE server. You can also download the driver RPMs from the Sun Fire X4140, X4240, or X4440 server web site. The downloads links are at
http://www.sun.com/servers/blades/x6200/downloads.jsp.

To Copy Files From the Tools and Drivers CD

2. Create a temporary directory to copy the PXE support files to. Enter the following command:

# mkdir /tmp

3. Mount the CD-ROM drive. Enter the command:

# mount /dev/cdrom /mnt/cdrom

4. Enter the following command to copy the files to the /tmp/ directory:

# cp /mnt/cdrom/support/pxeboot/tmp/

5. Uncompress and extract the contents of the tar file into the /tmp/ directory.

# tar -zxf /tmp/

When you extract the file, a directory with all required files is created at /tmp/sles10-pxefiles/.

6. Unmount the CD/DVD by entering the following command:

# umount /mnt/cdrom

7. Remove the Tools and Drivers CD from the server.

Configuring a DHCP Server

Complete the following steps on the server that will be your DHCP server.

To Configure a DHCP Server

1. Power on the server and log in as superuser.

2. Determine whether the DHCP server package is already installed on the server. Enter the following command:

# rpm -qa | grep dhcp-server

3. If the DHCP server package is not listed, install the package using YaST. Enter the following command:

# yast -i dhcp-server

4. Set up your DHCP configuration file (for example, /etc/dhcpd.conf) so that only PXEClient requests receive PXEClient responses.

Add the following entry to the DHCP configuration file (refer to the dhcpd.conf man page for more information).

class “PXE” {match if substring(option vendor-class-identifier, 0,9) = “PXEClient”; option vendor-class-identifier “PXEClient”; vendor-option-space PXE; next-server n.n.n.n;}

Where n.n.n.n is the IP address of the server.

Note - You can start with a sample DHCP configuration file in the /tmp/sles10-pxefiles directory.

5. In the DHCP configuration file, edit the server-identifier entry:

server-identifier n.n.n.n

Where n.n.n.n is the PXE/dhcp server’s IP address.

6. Also in the DHCP configuration file, find the subnet entry fields:

subnet 1.2.3.0 netmask 255.255.255.0 {

range dynamic-bootp 1.2.3.100 1.2.3.200;

option routers 1.2.3.1;

option broadcast-address 1.2.3.225;

}

Edit the subnet, range, router and broadcast-address entries according to the PXE/dhcp server’s network configuration.

7. Edit the /etc/sysconfig/dhcpd file and verify that the DHCPD_INTERFACE is set to the interface that is connected to the network you are planning to run the PXE server.

For example, if you are using Ethernet interface 0, the DHCPD_INTERFACE variable would be set as follows:

DHCPD_INTERFACE="eth0"

8. Start the DHCP service. Enter the following command:

# /etc/init.d/dhcpd start

9. Configure the server to always start DHCP. Enter the following command:

# chkconfig dhcpd on

Installing Portmap

Complete the following steps on your DHCP server.

To Install Portmap

1. Determine whether the portmap server package is already installed on the server. Enter the following command:

# rpm -qa | grep portmap

2. If portmap is not listed, install the package using YaST. Enter the following command:

# yast -i portmap

Configuring the TFTP Service

Complete the following steps on your DHCP server.

To Configure the TFTP Service

1. Determine whether the TFTP server package is already installed on the server. Enter the following command:

# rpm -qa | grep tftp

2. If the TFTP server package is not listed, install the package using YaST. Enter the following command:

# yast -i tftp

3. Edit and save the /etc/xinetd.d/tftp file.

Make the following changes:

Change the -s /tftpboot entry to -v -s /home/pxeboot

Change the disable attribute to no

4. Restart the inetd server. Enter the following command:

# /etc/init.d/xinetd restart

Configuring Syslinux

Complete the following steps on your DHCP server.

To Configure Syslinux

1. Determine whether the syslinux package is already installed on the server. Enter the following command:

# rpm -qa | grep syslinux

2. If the syslinux package is not listed, insert the RHEL CD and install syslinux by entering the following commands.

# mount /dev/cdrom /mnt/cdrom

# -Uvh /mnt/cdrom/suse/x86_64/syslinux

3. Remove the CD from the server after you enter the following command:

# umount /mnt/cdrom

Make sure pxelinux.0 and pxlinux.cfg/ are in the /home/pxeboot directory. If not, copy these files to the /home/pxeboot directory.

Configuring the NFS Service

Complete the following steps on your DHCP server.

To Configure the NFS Service

1. Determine whether the NFS service package is already installed on the server. Enter the following command:

# rpm -qa | grep nfs-utils

2. If the NFS service package is not listed, install the package using YaST. Enter the following command:

# yast -i nfs-utils

3. Edit and save the /etc/exports file to add the following line to it:

/home/pxeboot *(sync,no_root_squash,no_subtree_check,insecure)

4. Start the NFS service. Enter the following command:

# /etc/init.d/nfsserver start

5. Configure the server to always start the NFS service. Enter the following commands:

# chkconfig nfslock on

# chkconfig nfsserver on

Note - If you are using a DNS server, verify that DNS entries exist for the range of addresses defined in the PXE subnet dynamic-bootp entry in the dhcpd.conf file. If you are not using a DNS server, edit the /etc/hosts file to add the range of host addresses found in the PXE subnet dynamic-bootp entry in the dhcpd.conf file.

Disabling the Firewall

If a firewall is enabled on your PXE/DHCP server, you must disable it before attempting to install a PXE image onto the client system.

Caution - Network security vulnerability. When you disable the firewall protection on the system that is your PXE server, the security of the data on that server cannot be ensured. If this server is networked outside of your local intranet, be sure to re-enable the firewall after downloading software to PXE clients.

To Disable the Firewall

1. Execute the YaST command. Enter the following command:

# yast

2. Select Security & Users.

3. Select Firewall.

Select none to disable the firewall for all network interfaces.

Select specific interfaces to enable the firewall on those only.

Installing SLES 11 Using PXE

PXE is a powerful and convenient solution for setting up a number of Sun Fire X4140, X4240, or X4440 servers so that their configuration is identical.

Required Items

The PXE installation procedure requires the following items:

The DHCP server that you set up when you preconfigured your network to support PXE installation equipped with a CD/DVD drive

SLES 11 media CD set

Sun Fire server Tools and Drivers CD

Before You Begin

The network interface card (NIC) in your Sun Fire X4140, X4240, or X4440 server supports the Preboot Execution Environment (PXE) network booting protocol. The system BIOS and network interface BIOS on your server automatically query the network for a DHCP server.

Before you perform the procedures in this section, you must have configured your Linux network to support a PXE server (see Preconfiguring Your Network to Support PXE Installation of SLES 11).

The two procedures in this section are:

Creating a SLES 11 PXE Install Image on the PXE Server

Installing SLES 11 From a PXE Server

Creating a SLES 11 PXE Install Image on the PXE Server

To transfer the SLES 11 PXE files for installation you must:

1. Create a SLES 11 image on your PXE server.

2. Set up and copy SLES 11 software to a directory.

3. Set up the PXE files.

To Create a SLES 11 Image on Your PXE Server

1. Insert the Tools and Drivers CD into the DVD-ROM drive.

2. Copy the PXE support files from the Tools and Drivers CD into the /tmp directory by typing the following commands:

# mount /dev/cdrom /mnt/cdrom

# cp -a /mnt/cdrom/support/pxeboot/tmp

# cd /tmp

# tar xfz

# umount /mnt/cdrom

Set Up and Copy SLES 11 Software to a Directory

The following steps explain how to create the directory setup containing SLES 11 files for PXE installation.

Note - You can use a different target directory than the /home/pxeboot/sles10/ directory shown. The examples in this procedure use this directory.

1. Set up the directory structure that will hold the SLES 11 files. Enter the following commands:

# mkdir -p /home/pxeboot/sles10/CD1

# mkdir -p /home/pxeboot/sles10/CD2

# mkdir -p /home/pxeboot/sles10/CD3

# mkdir -p /home/pxeboot/sles10/CD4

2. Insert SLES 10 CD 1 into your server and copy its content to your PXE server. Enter the following command:

# mount /dev/cdrom /mnt/cdrom

# cp -r /mnt/cdrom/* /home/pxeboot/sles10/CD1/

# umount /mnt/cdrom

3. Remove SLES 11 CD 1 from the server.

4. Repeat the above procedure for copying CD 2, 3 and 4 to their corresponding directories in /home/pxeboot/sles10/ as given below:

# cp -r /mnt/cdrom/* /home/pxeboot/sles10/CD2/

# cp -r /mnt/cdrom/* /home/pxeboot/sles10/CD3/

# cp -r /mnt/cdrom/* /home/pxeboot/sles10/CD4/

Set Up PXE Files

1. Copy the autoinst.xml file from the /tmp/sles10/ directory to the root of the PXE image. Enter the following command:

# cp /tmp/sles10/autoinst.xml /home/pxeboot/sles10/

2. On your PXE server, modify the file home/pxeboot/pxelinux.cfg/default adding the following entry to it:

Note - In the text block below, copy from “append” through “autoinst.xml” as one continuous line with no returns.

default sles10 label sles10 kernel sles10/CD1/boot/x86_64/loader/linux append textmode=1 initrd=sles10/CD1/boot/x86_64/loader/initrd install=nfs://n.n.n.n/home/pxeboot/sles10/CD1 autoyast=nfs://n.n.n.n/home/pxeboot/sles10/autoinst.xml

Where n.n.n.n is the IP address of your PXE server.

3. Save and exit the file.

Installing SLES 11 From a PXE Server

This procedure describes the final step of installing the SLES 11 boot image onto your Sun Fire X4140, X4240, or X4440 server. Before proceeding with this procedure you must have done the following:

Configured your Linux network to support a PXE server. See Preconfiguring Your Network to Support PXE Installation of SLES 11.

Installed a SLES 11 image on that Linux PXE server. See Creating a SLES 11 PXE Install Image on the PXE Server.

To Install SLES 11 From a PXE Server

1. Connect the PXE client to the same network as the PXE server.

2. Power on the PXE client and press F12 to select network boot.

3. When you are prompted at the boot: prompt, enter in the label you gave the image when you installed the SLES 11 image on the PXE server (sles10 in the example above).

4. To configure your SLES 11 Linux server, refer to the Installation and Administration guide on SLES 11 CD 1.

5. Perform an Online Software Update to update the OS files (see Updating the SLES 11 OS).

Updating the SLES 11 OS

The SLES OS installation media might not contain the most up-to-date versions of the SUSE software. This procedure describes how to update the SLES OS on your server after you have installed it from a PXE server or distribution CDs.

To Update Your SLES OS

1. Log in as the superuser.

2. Enter the following command to run the YaST Online Update:

# you

Note that YaST can operate in both text and graphical modes. These directions apply to both.

3. If you are behind a network firewall and need to use a proxy server in order to access the internet, you must first configure YaST with the correct proxy information.

a. Select the ‘Network Services’ tab on the left, then the ‘Proxy’ screen on the right. Enter the correct proxy URLs in both the HTTP and HTTPS fields.

Note - In order for the on-line update service to function correctly through a network HTTP proxy, the following additional configuration step must be performed.

b. Exit the YaST utility and run the following command:

rug set-prefs proxy-url proxy URL

where proxy URL is the fully qualified URL of your proxy server (for example: http://proxy.yourdomain:3128/).

c. After successfully running the command, launch YaST again.

4. Register with the Novell Customer Center. Select the ‘Software’ tab on the left, then select ‘Novell Customer Center Configuration’ and follow the directions.

You will need your Novell Customer Center username and password, as well as a SLES product activation code.

5. Once registered, select the ‘Online Update’ tab to perform the software update.

Updating the SLES SCSI Drivers

To Update the SLES SCSI Drivers:

1. Insert the Tools and Drivers CD for your server.

2. Mount it onto the directory /mnt

# mount /dev/cdrom /mnt

3. Enter the following commands:

# cd /mnt/Linux/drivers

# rpm -ivh driver-filename

For example for SLES 11 SP1 and SP2, 64-bit:

# cd /mnt/Linux/drivers

# rpm -ivh mptlinux-4.00.43.00-1-sles10.x86_64.rpm

Note - Check the /linux/drivers directory on your Tools and Drivers CD for the specific driver file name for your operating system.

4. Installation of the new drivers is now complete. Reboot the server for the changes to take effect. Enter:

# reboot
