Very Computer

Hi!
I'm trying to install RH 7.1 on an Intel server (dual P3-1ghz, 512mb RDIMM
etc) with the AMI MegaRAID 1600-controller (493). RH 7.1 detects the
controller, I'm able to select the packages wanted as well as specifying
what partitions/sizes to use. It also says that the sda-partition has to be
initialized, and I have to press 5 times in order to continue. However, when
I'm done and have pressed the OK button in order to start installing I get
the message:
"Unable to format /. This may be a serious error".

Anyone familiar with this? I've tried RH 7.0 (2.2.16-22enterprise kernel)
which works great. However, as I'd like the 2.4 kernel in order to run
Vmware G6-server. I then compiled the 2.4.3-ac9 kernel and tried booting up.
The kernel recogizes the controller and disk-array, but says:

SCSI device sda: 286875648 512 byte hdwr sectors (146880 MB)
 sda: unknow partition table

blah-blah-blah......

VFS: Cannot open root device "801" or 08:01
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 08:01

This looks like a 2.4 kernel problem and my controller. I've tried mailing
AMI-support, but not much response from them yet.

Anyone??

Best regards,
Oliver Olsen

With RH 7.0, were you using the stock standard kernel?? Some manufacturers
(Dell and others) include customised patches in their kernels to support
their hardware (RAID controllers in particular). If this is your case then
try and visit the server maker we-site and look for patches that will work
with your setup.

Regards,

Roberto.

My server is one of the server-packs you can buy from Intel (yes, case,
mobo, cpu's are from Intel) and yes, I used standard kernel as I am booting
from the cd.
The AMI-card is bought separately, and I naturally tried AMI for support.
However, their support is the worst I've ever experienced. Totally arrogant
with one-line answers and no useful info whatsoever.
I've tried several news-groups as well as Bugzilla. No solution here yet. I
know Dell use some of these controllers (guess they have "Dellified" the
firmware/BIOS) but they claim a working driver is included with RH 7.1.
Guess I'll have to stick with RH 7.0 and the 2.2 brach if no solution is
found shortly.

I installed rh7.1 (seawolf) on machine with a AMI Elite 1600 (2ch).
I did not install the os on the raid, it is used for a data drive. But it
was recognized and I was able to setup the mount during the installation.
