hardware raid (adaptec 1200A)?

hardware raid (adaptec 1200A)?

[nbecker]

I'm setting up a new machine with a pair of IDE drives connected to
adaptec 1200A controller.  I defined a RAID-0 array using the adaptec
bios, but linux doesn't see it as a single drive.  It just sees two
drive, hde and hdg (each at their physical sizes).  Any hints?

Not conversant with the 1200 as such, but in any hardware raid, Linux
should always see it as a single drive.. Otherwise you simply have not
set up the RAID device correctly..

I think the adaptec 1200A is just another low-cost
not-quite-hardware-raid controller. As far as I have heared it is based
on Highpoint-Tech's HPT370. There is raid-0 support implemented in the
kernel.

be sure to enable CONFIG_BLK_DEV_ATARAID_HPT=y

The volumes should show up as /dev/ataraid/d[0-9]p[0-9] (major
blockdevice number 114).

bye,
Wilfried
