6.4 Step-by-step iSCSI SAN Boot implementation This section describes the step-by-step implementation tasks needed to set up the iSCSI SAN Boot installation. In our sample configuration, we use the following components: ► IBM System x3550 M3 server ► QLogic iSCSI HBA hardware initiator card - QLE4060C ► IBM DS5020 storage subsystem with v7.60.40 controller firmware ► IBM DS Storage Manager v10.70 6.4.1 Host configuration Tip: The implementation steps can vary, depending on the particular host type and operating system that are involved. This section illustrates how to configure the QLogic iSCSI Card for iSCSI boot and assumes that an iSCSI target has not previously been configured on the HBA. Before you begin: ► Ensure that the latest BIOS and firmware is installed on the HBA. ► Ensure that the storage device and Ethernet switch (if used) are both powered up and completely initialized before proceeding further. ► Ensure that only the primary iSCSI host HBA path is plugged into the network switch at this time. Leave the secondary iSCSI host HBA path cable unplugged for now. 402 SAN Boot Implementation and Best Practices Guide for IBM System Storage
Server BIOS configuration To configure the server BIOS, perform the following tasks: 1. Power on the server and press the F1 key to interrupt the boot sequence and enter the server system BIOS. 2. Select Devices and I/O Ports from the main menu, as shown in Figure 6-4. Figure 6-4 Devices and I/O Ports Chapter 6. iSCSI SAN Boot implementation with IBM System Storage DS5000 403
