I had install megaraid_sas-v00.00.03.16-1.noarch.rpm for kernel 2.6.18-53.1.13.el5.028stab053.10, but unsuccessful, reboot and kernel panic. Server is DELL 2950.

Any idea?

Hi Paveo,

could you please explain, why you need to install any additional drivers? This our kernel based on RHEL5 and as far as I know it includes this driver. Are you tried to use it?

thank you,
Vasily Averin

Thanks for your reply.

My server reports the warning like this(Dell OMSA):

Driver Version 00.00.03.10
Minimum Required Driver Version 00.00.03.13

My raid card is Dell PERC 5/i Integrated, OMSA said my system's Firmware and Driver versions are out of date, so I want to upgrade it but kernel panic happened. Sad

ok, thank you for explanation.

I expect the new driver was re-compiled incorrectly. Could you please show me the logs of this procedure?

The kernel crash messages are interesting for me too.

thank you,

1.gif shows the messages
megaraid_sas: disagrees about version of symbol struct_module
insmod /lib/megaraid_sas.ko: -1 Invalid module format.

These messages means that the module was re-build incorrectly (or may be it was compiled for some other kernel).

You need to rebuild it again. You can use auto-build again -- in this case I would like to look at the messages.
Also if you wish I can explain You how to re-build thsi module manually.

thank you,

The problem module was built by dkms tool, I try to rebuild it with no effect.

Thank you very much to tell me how to build a working module Smile

First of all -- I wold note that you need to build this driver by the same comiler that was used for the kernel build.

Do you have RHEL5 host OS? If not -- You need to create new Container based on this template, and install the kernel and kernel-devel packages -- it contains the Makefiles and headers reuired for the driver compilation.

Then you need take megaraid_sas-v00.00.03.16-src.tgz tarball, it is included into megaraid_sas-v00.00.03.16-1.noarch.rpm, in /usr/src/megaraid_sas-v00.00.03.16-1 directory.

Extract it by using "tar xvzf" command, cd to dkms_source_tree/ directory and look at the following files:
Makefile
megaraid_sas.c
megaraid_sas.h

Then you can compile the driver by using the following command:
make -C /lib/modules/<kernel version>/build \
SUBDIRS=<full_path_to_the_current_dir> modules

for example

# make -C /lib/modules/2.6.18-028stab053.10/build \
SUBDIRS=/root/dkms_source_tree/ modules
make: Entering directory `/usr/src/kernels/2.6.18-028stab053.6-i686'
CC [M] /root/dkms_source_tree/megaraid_sas.o

/root/dkms_source_tree/megaraid_sas.c: In function ‘megasas_resume’:

LD [M] /root/dkms_source_tree/megaraid_sas.ko
make: Leaving directory `/usr/src/kernels/2.6.18-028stab053.6-i686'
#

As you can see it generates some warnings but I think it is not an issue in our case.
