-Hardware configuration

• You must choose the same type of HDDs for a RAID drive.
• LSI Logic Embedded MegaRAID is not available on this distribution.

-Evaluation

(*1)
You need to create a RAID driver beforehand by another development environment.
Ubuntu-server needs two the drivers, for generic kernel and for server kernel. Ubuntu-desktop needs only the driver for generic kernel.

* Making the driver -- Driver created in the steps below can be got from here.

1. Download Ubuntu_10.04_LTS_05.30.zip the deiver package from LSI.
2. Take out megaraid_sas-v00.00.05.30-src.tgz from the package.
3. Execute the following comands in the 2.6.32-38-generic development environment. The megaraid_sas.ko will be created.
   $ sudo -s
   # cd /usr/src
   # ln -s linux-headers-2.6.32-38 linux
   # tar zxvf megaraid_sas-v00.00.05.30-src.tgz
   # cd megaraid-sas-v00.00.05.30
   # make -C /lib/modules/2.6.32-38-generic/build/ M=`pwd`
   
4. Ubuntu-server needs the megaraid_sas.ko for server kernel. Execute above steps in 2.6.32-38-server development environment.
5. Copy the driver(s) in the USB storage.
   In the following, it is assumed that generic/megaraid_sas.ko is for generic kernel, server/megaraid_sas.ko is for server kernel in the USB storage.

* Installation

1. When the installer starts up, go to the console by pressing Ctl + ALT + F2.
2. If "$" prompt appears, conduct the following command.
   $ sudo -s
3. Connect the USB storage that contains the megaraid_sas.ko, check the drive letter of the USB storage (such as /dev/sde) by the following command. In the following, it is assumed that it is '/dev/sde'.
   # dmesg | grep ' sd'
4. Execute the following comands.
   # mount -t vfat /dev/sde1 /mnt
   # cp -f /mnt/generic/megaraid_sas.ko /lib/modules/2.6.32-38-generic/kernel/drivers/scsi/megaraid/
   # modprobe megaraid_sas
   
5. Ubuntu-server needs followings, additionally.
   # mkdir -p /lib/modules/2.6.32-38-server/kernel/drivers/scsi/megaraid/
   # cp -f /mnt/server/megaraid_sas.ko /lib/modules/2.6.32-38-server/kernel/drivers/scsi/megaraid/
   
6. Remove the USB storage after the next command.
   # umount /mnt
   
7. Return to the installer by pressing ALT + F7 or Alt + F1, continue with the installation.
   
8. When "Installation complete" appears, don't restart and go to the console again with Ctl + ALT + F2.
9. If ubuntu-desktop, execute the following comands.
   # cd /lib/modules/2.6.32-38-generic/kernel/drivers/scsi/megaraid/
   # cp -f megaraid_sas.ko /target/lib/modules/2.6.32-38-generic/kernel/drivers/scsi/megaraid/
   # cd /target/boot
   # mkinitramfs -k -o initrd.img-2.6.32-38-generic
   
10. If ubuntu-server, execute the following comands.
    # cd /lib/modules/2.6.32-38-server/kernel/drivers/scsi/megaraid/
    # cp -f megaraid_sas.ko /target/lib/modules/2.6.32-38-server/kernel/drivers/scsi/megaraid/
    # chroot /target
    # cd /boot
    # mkinitramfs -k -o initrd.img-2.6.32-38-server 2.6.32-38-server
    * Warning that "grep: /proc/modules: No such file or directory" is displayed, but can be ignored.
11. Return to the installer by pressing ALT + F7 or Alt + F1 and complete the installation.

Updating the LAN drivers

*On Board LAN Controller( tg3: -> 3.122n )

1. You need development environment such as gcc.
2. Download linux-3.122n.zip the driver for BCM5718 from Broadcom.
3. Copy the driver package to /tmp.
4. Execute the following comands.
   # cd /tmp
   # unzip linux-3.122n.zip
   # cd Server/Linux/Driver
   # tar zxvf tg3-3.122n.tar.gz
   # cd tg3-3.122n/
   # make
   # make install
   # modprobe -r tg3
   # modprobe tg3
5. Update the initrd image.
   ex. # mkinitramfs -o /boot/initrd.img-2.6.32-38-generic
6. Reboot and configure networking.

(*3)
If the I/O load is very high and the amount of memory is small, Call Trace may be logged in the syslog .

(*4)
The following message is registered in the syslog on each boot.
Not enabling x2apic, Intr-remapping init failed.
ACPI Error: No handler for Region [OEM2] (f74172d0) [IPMI] (20090903/evregion-319)
ACPI Error: Region IPMI(7) has no handler (20090903/exfldio-295)
ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PMI0._PMM] (Node f7416ba0), AE_NOT_EXIST

(*5)
The system may stop in the middle of the boot with the following display in rare cases. You must push the DC button to recover.
run-init: nuking initarmfs contents: Directory not empty
[ X.XXXXXX ] kernel panic -not syncing: Attempted to kill init!
