Hello@all

and tried to setup SME but no drives are seen what can i do?
LSI Megaraid used inside. with a ubuntu live cd 9.0 the kernel
message appears "MPT-Bios-Bug.. at boot?

What you can do is check the megaraid against the appropriate red hat hardware compatability lists as listed in the SME wiki.

Hello

seems to be a unsupported Perc Card how can i see the revision number?
lspci wrote LSI-53c1030 PCI-X but the Webbios shows ATA-Drives?

The Perc BIOS revision should appear briefly on the console at boot. The PERC setup utilities should also be able to display the revision.

Have you tried entering the machines Service Tag number at the Dell support site with red hat selected as the OS?

i have made a short setup of debian lenny

some forum on net describes to build own driver disk
with a setup of Centos 4.7 at another PC
for Kernel 2.6.9
i am a little bit down cause debian+ubuntu-server have the driver
inside the kernel

do get precompiled Driver and easy Install Instruction go to my Blog
http://my.opera.com/linuxonlinehelp/blog/centos-4-7-4-8-sme-server-7-4-megaraid-ata-perc-driver

Howto:
For install of Centos 4.7 4.8 and SME Server 7.4 with

Kernel 2.6.9-89.0.16.EL
Kernel 2.6.9-89.0.16.ELsmp

take my compiled Driver

/lib/modules/2.6.9-89.0.16.ELsmp/kernel/drivers/scsi/megaraid
look for only this modules, remove old or other!
megaraid.ko (my)
megaraid_mm.ko
megaraid_sas.ko

edit with:
#nano /etc/modprobe.conf
change first line!!! to:
alias scsi_hostadapter megaraid
go:
cd /boot
make:
mv initrd-2.6.9-89.0.16.ELsmp.img initrd-2.6.9-89.0.16.ELsmp.img.org
run to make new kernel-initrd:
mkinitrd initrd-2.6.9-89.0.16.ELsmp.img 2.6.9-89.0.16.ELsmp
check for new kernel-initrd:
ls [Enter]
shows:
initrd-2.6.9-89.0.16.ELsmp.img
..ok try to reboot..

Attention! After every signal-event post-upgrade/yum update check
modprobe.conf for first line!!! is set to "megaraid"

Enjoy your old PERC 2/3 Raid Controller...
