!!!1. Introduction
The goal of this HOWTO document is to explain how to setup RAID 1 (mirroring) with the two hard disks and install bootable !RedHat Linux Operating System on the mirror device. This document discusses both methods of achieving this goal: 1. Using Promise supplied driver 2. Using Linux native RAID. If you choose the first method (using Promise supplied driver), you must use the Kernel 2.4.7-10 that comes with !RedHat 7.2 CD. If you choose the second method, you can upgrade the kernel to the latest kernel (2.4.18). This document does not discuss Striping or other disk configurations, although the author believes that this document might help setup those configurations. This document does not yet cover: 1. Installation using GRUB instead of LILO and 2. Installation with Latest development kernels (2.5.x).

When we experience problems booting a Linux machine with RAID, we may have to use an appropriate ''Append Line''. Therefore, it is important to determine and write down the ''Append Line''. This will help you fix your problems later or upgrade your kernel smoothly or add/remove additional hard disks.

The two free disks above (hde and hdg) are the ones we would like to setup as RAID 1 to create /dev/ataraid/d0 raid device. Note that we do not have hdf or hdh because that is how we used the IDE/RAID ports on Promise chip. It is not a good idea to connect two hard disks to the same Promise controller IDE port. In the above example, we used Primary Master and Secondary Master connections on the Promise Technology card.

From this output, we learn that our Promise Technology card uses IRQ 10 for both ide ports (ide2 and ide3). Using same IRQ is perfectly alright as long as your kernel supports PCI IRQ Sharing. By default, our Linux kernel is configured to support PCI IRQ sharing. From the above output, we also learn that our Promise Technology card uses various IO addresses. For the purpose of identifying Promise Technology disks properly at boot time, we only want the IRQ number(s) and the first four IO Address numbers outside [[ ]. Write down on a piece of paper this information. In this case, from the above output:
-
-
-
-IRQ2 = 10
-IO1 = 0x9400
-IO2 = 0x9000
-IO3 = 0x8800
-IO4 = 0x8400
+
IRQ1 = 10
+ IRQ2 = 10
+ IO1 = 0x9400
+ IO2 = 0x9000
+ IO3 = 0x8800
+ IO4 = 0x8400
Now, we have to evaluate the following to obtain the correct ''Append Line''. Then either specify this ''Append Line'' at boot time or specify it in lilo configuration file.
-
-
-
-
+
ideX=IO1,IO2+0x0002,IRQ1 ideY=IO3,IO4+0x0002,IRQ2
where ideX and ideY are the two IDE ports of Promise card our free disks are using.
In our example, the above ''Append Line'' will become:
-
-
-
-
+
ide2=0x9400,0x9002,10 ide3=0x8800,0x8402,10
If, for example, we want to boot kernel version 2.4.18, labelled linux according to /etc/lilo.conf, then we specify our ''Append Line'' in one of the following two methods:
