There are several possible configurations of a Dell 2650 from the factory, so what I figure we should do is create a table of known configurations and hardware combinations.


Gentoo Installation Instructions - SCSI Models

Loading the Installation CD

Boot up a gentoo installation CD with the doscsi argument,

 gentoo doscsi 

Note :- Found that Dell 2650 froze the installation (no keyboard). By adding noapic to the above boot command fixed the problem and installation completed.

You should see each mirror as a /dev/sda, /dev/sdb, /dev/sdX device. My system for example has a RAID 1 array using the first two discs, and a RAID 5 array using the remaining 5 disks. So my devices are

  1. /dev/sda - raid 1 array, looks just like a normal scsi disk
  2. /dev/sdb - raid 5 array, looks just like a normal scsi disk

Configuring the hard disks - 2 drive version

Configuring the hard disks - 5 drive version

Configuring the Kernel

Note that below I compile` the e100 and e1000 as modules, because if you do this it lets you control which interface is eth0, and which one will be eth1, by the order you specify their loading in /etc/modules.autoload.d/kernel-2.6 (if using kernel series 2.6.x)

  1. Enable the SvrWorks chipset in the ATAPI drivers section (Compiled In)
  2. Enable the aacraid driver in the SCSI/Low Level Drivers section (Compiled In)
  3. Enable the e1000 driver in the 1000 Mbit ethernet card section (Module)
  4. Enable the e100 driver in the 100 MBit ethernet card section (Module)
  5. Enable Device Mapper support in the RAID device section, compile this in as a module

Note:- Check the version of Gigabit card - the Dell 2650 I used required the Broadcom Tigon3 driver not the e1000 - run lspci to verify the adapter
