1 Introduction Traditionally, servers are configured to install the operating system on internal direct-attached storage devices. With external booting from HBAs or RAID arrays, server-based internal boot devices can be eliminated. Booting from an external device provides high-availability features for the operating system during the boot process by configuring the HBA BIOS with redundant boot paths.
2 Configuring HBAs NOTE: • Although the procedures in this chapter refer to HBAs, they apply to all supported adapter types (HBA, CNA, LOM, and mezzanine cards). • For Windows servers, only one boot path must be configured. IMPORTANT: HP recommends disabling HBA BIOS on HBAs that are not part of BFS. HBA/CNA/LOM/mezzanine cards provide BFS functionality. When adapters are configured to boot from the disk device on the SAN, the server boots as if the SAN disk were a local disk.
16. • • For servers running Windows: 1. Complete the operating system build. See “Installing the operating system” (page 10). 2. Install multipathing software. 3. Proceed to Step 17. For servers running Linux: 1. Complete the operating system build. See “Installing the operating system” (page 10). 2. If multipathing software is not already configured, configure multipathing software. 3. Proceed to Step 17. 17.
f. Select the alternate device from which to boot, and then press Enter. 13. Repeat Step 12 for all controller ports in the array. 14. Press Esc twice to save the changes, and then select Save Changes. The configuration changes to the selected HBA are saved. 15. From the Fast!UTIL Options menu, select Select Host Adapter, and then press Enter. Select the other HBAs and repeat Step 2 through Step 14. 16. Press Esc twice to save the changes. Initial setup is complete. 17. Reboot the server.
NOTE: FCoE boot is only supported on DCB enabled configurations. 6. 7. 8. 9. 10. 11. Select MBA Configuration, and press Enter. Configure Boot Protocol field to FCoE and press Esc. Select FCoE Boot Configuration and press Enter. Select Target Information and press Enter. From the list, select the first available path and press Enter. Set the connect parameter to Enabled. Enter the target WWPN and Boot LUN ID for the target to be used for boot. 12.
3 Best practices Consider the following: • For Windows, a single path to a single LUN must be created before starting the build process. • Verify the boot order in the server RBSU and ensure that the boot HBA is positioned correctly. • In Microsoft Windows 2008 server, ensure that the USB key is positioned below the hard drive C. • When the build process is complete, BFS driver kit must be upgraded to the full Smart Component driver kit. • Read the release notes for the latest required updates.
4 Installing the operating system Emulex, QLogic, and Brocade HBAs NOTE: Although the procedures in this chapter refer to HBAs, they also apply to all supported Emulex and QLogic adapter HBA, CNA, LOM, and mezzanine card types. Linux Verify that there are multiple paths to the LUNS before installing a Linux operating system. Red Hat Enterprise Linux 1. 2. Start the installation of the operating system. Provide the parameter linux mpath to the kernel boot line.
Loading the HBA driver for a Microsoft Windows Server 2003 install To load the driver: 1. Insert the HP Smart Setup CD. 2. From the EBSU menu, select Bootable DVD, and then press Enter. 3. Select Load OEM Boot driver or press B to display the Load OEM Boot Driver window. 4. Select the Fibre Channel HBA, and then press Enter. 5. Press Tab once, and then press Enter to load the driver. The system displays a message confirming that the driver is loaded. 6. Select Exit or press X to exit.
5. 6. 7. 8. 9. Select a Disk to Install VMware ESXi appears. Locate and select the configured in Adapter BIOS and press Enter. Select the appropriate layout of the keyboard and press Enter. Enter the root password, ensure that password must match. Press Enter to continue. Press F11 to confirm the installation. Installation is complete. Remove the installation media and press Enter to reboot. NOTE: For specific ESX/ESXi 3.x, 4.x, and 5.x installation documentation, see http:// pubs.vmware.com/.
7. 8. 9. 10. 11. 12. 13. 14. 15. Click Add Advanced Target. Select Add FCoE SAN and click Add Drive. Select each interface intended for FCoE boot, clear Use DCB, select Use auto vlan, and click Add FCoE disk(s). Ensure that all FCoE-visible disks are seen under ‘Multipath Devices’ or ‘Other SAN Devices’ or both, as appropriate. Repeat steps 8 to 10 for all initiator ports. Click Next and complete the installation. The system reboots after installation is complete.
10. Continue with the installation. 11. Under the Expert tab on the Installation Settings screen, select Booting. 12. Select Boot Loader Installation tab and then select Boot Loader Installation Details. Ensure to have one boot loader entry and delete all redundant entries. 13. Click OK and complete the installation. Windows Microsoft Windows Server 2008 SP2/R2 1. 2. 3. 4. Insert Microsoft Windows Server 2008 SP2/R2 CD in the DVD drive and select Bootable DVD.
1. 2. 3. Boot from the updated ESXi installation image and select ESXi installer when prompted. Follow the instructions on the screen to continue the installation process. Reboot the system. VMware Best Practices • Follow HP recommendation from the specific server booting from a SAN. • Enable and configure the adapter correctly, to allow it to access the boot LUN. • Each host must have access to its own boot LUN only and not others.
