Setting up iSCSI boot clients with a Flex daemon on an OpenSUSE server

This section describes how to set up an OpenSUSE 10.3 server to:

• Act as a PXE network boot server
• Use the Double-Take Flex daemon

for the purpose of providing client systems the ability to boot their operating system from storage located on iSCSI SAN.

The process includes:

• Setting up the network interface
• Setting up the Double-Take Flex service to provide the necessary iSCSI boot parameters
• Setting up a DHCP server to assign IP addresses and provide a bootstrap name
• Setting up a TFTP server for the Double-Take Flex iSCSI bootstrap to be loaded

Requirements

• PXE boot-capable machine, GbE NIC recommended.
• Double-Take Flex Linux daemon - (supplies the bootstraps iscsinbp.0, iscsinbp.1, plus the iSCSI session parameters)
• Packages - all of them can be found on the DVD or in the main OpenSUSE repository.
• DHCP server - assign IP addresses, provided bootstrap name
• TFTP - delivers bootstrap to the PXE boot client
• yast2-tftp-server - graphical configuration tool for a TFTP server
• yast2-dhcp-server - graphical configuration tool for a DHCP server
• Network cable
• OpenSUSE 10.3 DVD

Configuration tools

All of the graphical configuration tools used in this document can be found in Yast2 in the Network Services section.
