5.9.1 SAN Boot using SUSE Linux Enterprise Server 11 SP2 Following are the general steps to set up a SUSE Linux host using SAN Boot: 1. Configure the Storwize V7000 Subsystem in a such way that only the boot volume you want is mapped to the host. Tip: Unlike other operating systems, with SUSE Linux Enterprise Server 11 SP2, it is recommended to have multiple paths configured between host and the SAN Volumes before installation of the operating system. 2. Configure and enable the HBA BIOS, as shown in 5.5.1, “Finding WWPNs of QLogic FC HBAs” on page 313 and/or 5.5.3, “Finding WWPNs of Emulex FC HBAs” on page 321. 3. Selecting the volume configured for SAN Boot (see section 5.4.5, “Creating a volume for SAN Boot” on page 298) and start the installation process. 4. After initializing the installation process, you come to the first window that gives various startup options. Choose Installation at the Welcome panel, as shown in Figure 5-97. Figure 5-97 Welcome to SUSE Linux Enterprise Server 11 installation 348 SAN Boot Implementation and Best Practices Guide for IBM System Storage
5. Select New Installation as the installation mode, as shown in Figure 5-98. Figure 5-98 Installation Mode Chapter 5. SAN Boot implementation with IBM SAN Volume Controller and IBM Storwize v7000 349
