|
|
</H2>
|
|
|
|
<P> Refer to the instruction manual to install the card and the
|
|
drives. For DPT, since a storage manager for Linux doesn't exist yet,
|
|
you need to create a MS-DOS-formatted disk with the system on it
|
|
(usually created using the command "format /s" at the MS-DOS prompt).
|
|
You will also be using the DPT storage manager for MS-DOS (available
|
|
from
|
|
<A HREF="http://www.adaptec.com">the Adaptec website</A>),
|
|
which you should probably make a copy of for safety.
|
|
<P> Once the hardware is in place, boot using the DOS system
|
|
disk. Replace the DOS disk with the storage manager. And invoke the
|
|
storage manager using the command:

|
|
<P>Wait a minute or so, and you'll get a nice menu of options. Configure
|
|
the set of disks as a hardware RAID (single logical array). Choose
|
|
"other" as the operating system.
|
|
<P> The MS-DOS storage manager is a lot easier to use with a mouse,
|
|
and so you might want to have a mouse driver on the initial system
|
|
disk you create.
|
|
<P> Technically, it should be possible to run the SCO storage manager
|
|
under Linux, but it may be more trouble than its worth. It's probably
|
|
more easier to run the MS-DOS storage manager under Linux.

<H2><A NAME="ss4.2">4.2 Configuring the kernel </A>
|
|
</H2>
|
|
|
|
<P> You will need to configure the kernel with SCSI support and the
|
|
appropriate low level driver. See the
|
|
<A HREF="http://sunsite.unc.edu/mdw/HOWTO/Kernel-HOWTO.html">Kernel HOWTO</A> for information on how to compile the kernel. Once you choose
|
|
"yes" for SCSI support, in the low level drivers section, select the
|
|
driver of your choice (EATA DMA or EATA ISA/EISA/PCI for most EATA DMA
|
|
compliant (DPT) cards, EATA PIO for the very old PM2001 and PM2012A
|
|
from DPT). Most drivers, including the EATA DMA and EATA ISA/EISA/PCI
|
|
drivers, should be available in recent kernel versions.
|
|
<P> Once you have the kernel compiled, reboot, and if you've set up
|
|
everything correctly, you should see the driver recognising the RAID
|
|
as a single SCSI disk. If you use RAID-5, you will see the size of
|
|
this disk to be 2/3 of the actual disk space available.

driver should look something like this:
