RAID driver cciss

[Kief Morris]

Hello, I'm new to FAI, I've been struggling to get it to work with 
some Compaq/HP Proliant servers. I've got one server going
(a DL320 G2), and now I'm working on a DL380 G2, which uses
the Smart Array 5i/532 RAID controller.

This machine already has Debian installed with a 2.4.18 kernel,
two virtual drives formatted with ext3 partitions. But when I boot
using FAI (2.4.1), the RAID controller is not recognized.

The setup_harddisks script has this:

    $result = `sh -c "LC_ALL=C sfdisk -d -q"`;

But when I run it from the command line I get nothing:

  phobos:~# sh -c "LC_ALL=C sfdisk -d -q"
  phobos:~#

Playing around with sfdisk and other utilities gets nothing:

  phobos:/tmp/fai# sfdisk -l /dev/cciss/c0d0
  /dev/cciss/c0d0: No such device or address

  sfdisk: cannot open /dev/cciss/c0d0 for reading


The only tool that admits the RAID controller exists is kudzu, which
puts out this:

-
class: RAID
bus: PCI
detached: 0
driver: cciss
desc: "Compaq|Smart Array 5i/532"
vendorId: 0e11
deviceId: b178
subVendorId: 0e11
subDeviceId: 4080
pciType: 1
-

I'm assuming the kernel FAI boots the machine with has the cciss
driver compiled in, since there are a few references to it in the archives
of this list. Is this true? Perhaps the driver version is different, but
surely the newer driver would still be able to recognize the disk exists
even if it has been partitioned and formatted by an older version of
the driver?

Does anyone have experience using FAI 2.4.1 with the Smart Array
controller? Did you have to do anything special? Any suggestions
for further investigation? I'm considering compiling a kernel for FAI
which I'm sure has the cciss driver as a next step.

Thanks,
Kief


More info: when I boot under the old system (hostname zephyr,
but the same system as phobos), I can get useful info using
sfdisk:

zephyr:~# sh -c "LC_ALL=C sfdisk -d -q"
# partition table of /dev/cciss/c0d0
unit: sectors

/dev/cciss/c0d0p1 : start=       32, size=  195808, Id=83, bootable
/dev/cciss/c0d0p2 : start=   195840, size= 3998400, Id=83
/dev/cciss/c0d0p3 : start=  4194240, size=16001760, Id=83
/dev/cciss/c0d0p4 : start= 20196000, size=15357120, Id=83
# partition table of /dev/cciss/c0d1
unit: sectors

/dev/cciss/c0d1p1 : start=       32, size=78123808, Id=83
/dev/cciss/c0d1p2 : start= 78123840, size=58596960, Id=83
/dev/cciss/c0d1p3 : start=136720800, size= 5532480, Id=82
/dev/cciss/c0d1p4 : start=        0, size=       0, Id= 0

The kernel:

zephyr:~# uname -a
Linux zephyr 2.4.18-686-smp #1 SMP Sun Apr 14 12:07:19 EST 2002 i686 unknown

sfdisk works too:

zephyr:~# sfdisk -l /dev/cciss/c0d0
