Installing Linux over the SAN without an IBM subsystem device driver

Use this process to install Linux over the SAN without an IBM subsystem device driver (SDD). These instructions only apply to QLogic adapter cards or to the eServer BladeCenter HS20. These instructions do not apply to a server with Emulex adapter cards.

1. Boot the server.
2. Press the <CTL-Q> message for the Fast!Util when it appears.
3. In the QLogic FAST!Util, select the controller that has your remote boot disks attached.
4. Click Configuration Settings → Host Adapter Settings and change the BIOS enabled setting to Enabled.
5. Click Configuration Settings → Selectable Boot Settings.
   1. Change the Selectable boot setting to Enabled.
   2. Set (Primary) Boot Port Name,Lun: to the first device in your list.
      Note: If you have assigned multiple LUNs and are using any of them to boot from (that is, if you have file systems such as /boot, /, /usr, /var, or the swap partition), you must list the LUNs in the subsequent entries, as well.
6. Save your changes.
7. Back out of the FAST!Util and reboot.
8. Insert modules disk modules2 into the diskette drive (see the previous procedure for creating modules disks).
9. Put the SP1 CD in the CD-ROM drive and reboot.
10. Select Manual Installation.
    Note: If you are using a Summit machine, you must add “apic” to the boot options at the bottom of the menu screen.
11. Select the appropriate keyboard and press Enter.
12. After manual installation, select the Kernel modules (hardware drivers) and Load IDE/RAID/SCSI modules options.
13. Select the QLA23xxxx module from the list, press Enter twice, leaving the parameters line blank.
14. Wait for the module to return from loading, and then press Enter.
15. Press the right-arrow key once to select the Back button, and press Enter again.
16. Select Start Installation/Update > Install > CD-Rom.
17. When you are prompted with “Please make sure that CD number 1 is in your drive!”, place the SLES 9 Install CD 1 CD into the CD-ROM drive and press Enter.
18. When you are prompted with “SUSE's End User License for SLES”, select Accept, and then select the appropriate keyboard. Click Accept.
19. During detection, if you are asked whether you want to make a New Installation, select New Installation and continue.
20. Create the partitions. (Normally, there are three: one of approximately 200 MB for /boot, a second of approximately 2 GB for swap, and the rest for /.)
21. Make the package selections, making sure to include the kernel source package.
22. Check your boot device parameters. In most cases, add “apic=off” to the load string. If you have loaded the apic boot option at the outset, it is listed automatically. If you used an APIC-enabled installation and the apic boot option is not listed automatically, add it. Failure to add the apic boot option results in a panic condition for the server at reboot.
23. Check your time zone parameter and change it to the appropriate time zone.
24. Check the clock setting. If it defaults to “UTC”, change it to “Local”.
25. Click Next and then click Yes when you are prompted. The system formats the remote disk, and then installs the packages.
26. Switch CDs when you are prompted.
    Note: To boot Linux, follow the instructions above to allow the server to boot.
