DELL PowerEdge 2800 Installation Guide
       
1. RAID configuation
Use PERC RAID S/W to Create RAID1(36Gx2) & RAID5(73Gx4), also call it channel 0 & channel 1.
       
2. Use Dell OpenManange Server Assistant to Install RedHat Linux ES(version3.0)
        And something wrong with X Windows, can not load Graphic window, I have to modify /etc/inittab,change id:3:initdefault:  to id:5:initdefault:
       
3. After OS Installation,
        Use 'fdisk -l' to list all Internal HardDisk (or System Tools>HardWare Browser)
        And you can find /dev/sda1(...7) and /dev/sdb
        Now you should mount the /dev/sdb ... It's big array ...
               
        Fdisk /dev/sdb
                1) software that runs at boot time
                2) booting and partitioning software from other os
        Command(m for help): p   //display disk information
        Command(m for help): n         //create a partition
                        E        extended
                        P         primary partition (1-4)

                P
                Partition number (1-4): 1
                First cylinder (1-26725), default 1): 1
                Last cylinder or +size or +sizeM or +sizeK (1-26725,default 26725):  26725

Command(m for help): w                        //after partition creation & save it
可以用m命令来看fdisk命令的内部命令；n命令创建一个新分区；d命令删除一个存在的分区；p命令显示分区列表；t命令修改分区的类型ID号；l命令显示分区ID号的列表；a命令指定启动分区；w命令是将对分区表的修改存盘让它发生作用。

4. mkfs -t ext3 /dev/sdb1
5. Mount /dev/sdb1 mannualy or automatically

如何不用Dell OpenManange Server Assistant 光盘,而直截手动配置硬RAID及安装OS
---------------------------------------------------------------

RAID Config Mannualy & OS instatllation    - collect by 仲龙@Nov.2004

Step 1:
上DELL站点下载一些RAID卡驱动
http://support.ap.dell.com/apjsite/Downloads/index.aspx

请输入7位机器编号(Service Tag:FVNNK1X)
SCSI RAID(阵列卡)
Redhat Enterprise Linux 3

In Device Selection, Choose LSI Logic PERC 4/Di,then 2 download type displayed in next page, one is Driver(ver2.10.7) and another is Application,
This driver in this page is what you want to get, click it:
http://support.ap.dell.com/apjsi ... mp;releaseid=R81652

In this page, you can find one file name with "perc-2.10.7-A10.tar.gz", download it right now else the network will be terminiate~. Untar this package, this files include in it and I list it at below:
                        dell-megaraid2-v2.10.7-32bit-1dkms.noarch.rpm
                        disk-info
                        dkms-1.10-1.noarch.rpm
                          GPL
                        install.sh
                        modinfo
                        modules.cgz
                        modules.dep
                        pcitable
                        perc-2.10.7-A10.txt
                        README.dkms
                rhdd-6.1

Step 2.
        Create a ext2 format floppy.
                Mke2fs /dev/fd0 1440
                Mount -t ext2 /dev/fd0 /mnt/floppy
                Cp /tmp/perc-4Di/. /mnt/floppy
Umount /mnt/floppy

Step 3.
        Boot the Server,
<ctrl>+<m>,进入PERC/CERC(4e di)Bios Configuration Utility U821,
        Configuration > New Configuration >
        Highlight READY 1 Disk then press "Enter",
        Hightlght READY 2 Disk then press "Enter",
        ...
        Then Initialize this RAID.
        Reboot the server

Step 4.
       
        Insert the OS Disc 1 into Optical Drive , boot the server
        At the Booting time , press F2 choose Option .
        In next interface, type "linux dd" (add driver mode)
        OS will ask you " Do you have a drive disk?"                         - "yes"
                                        "Driver Disk Source"                                         - "fd0"
        Then ask you to insert ur driver disk into /dev/fd0 and press "OK" button to continue
        System will reading floppy and install Megaraid2 driver, after this instation, ask u
        Load more driver disks, choose "No",
        This OS installation give u a CD Found tips, skip it .
        ...
        And the next is same like before.
