Actually I did this again recently and the directions still work,
Here is what I have on our internal Wiki here at Michigan,
begin
the sun array does not work with redhats DM-multipath rpm. Download
the linuxrdac source from sun and the lustre kernel source code.
Install the kernel source and link to /usr/src/linux
rpm -ivh kernel-lustre-source-2.6.9-67.0.7.EL_lustre.1.6.5.1.x86_64.rpm
ln -s linux-2.6.9-67.0.7.EL_lustre.1.6.5.1 linux
cd /usr/src/linux
make mrproper
cp /boot/config-`uname -r` .config
make oldconfig
make dep
make modules
There will be two directories, one ending in -obj and one not. The
directories scripts/mod scripts/genksyms need to be copied to the
one ending in -obj/scripts .
Once done untar the linuxrdac package and copy in a working
Makefile provided by This Makefile will not install
right, you will need to comment out the install of mppiscsi_umountall
It is not needed.
Makefile_linuxrdac-09.01.B2.74 rdac-LINUX-09.01.B2.40-source.tar.gz
make clean
make
make uninstall
make
make install
yes
Edit grub.conf to use the mpp initrd over the standard one:
initrd /initrd-2.6.9-67.0.7.EL_lustre.1.6.5.1smp.img
To:
initrd /mpp-2.6.9-67.0.7.EL_lustre.1.6.5.1smp.img
LUNs are accessible form a single SCSI block device, failover happens
in a few seconds, but not right away. CAM should notify you.
[r...@mds1 scripts]# /opt/mpp/lsvdev
Array Name Lunsd device
-
mds-raid0 - /dev/sdb
mds-raid1 - /dev/sdc
mds-raid2 - /dev/sdd
I hope that is enough detail for you,
/end
Again, sun sold us this array, but the sun packaged kernels didn't
come with support for it, annoying.
Maybe sun in the future will push their stuff into DM-Multipath, or
just package it with lustre.

i have tried the following suggestion from lustre
http://www.mail-archive.com/lustre-discuss@lists.lustre.org/
msg01682.html
i may not have changed the information enough
does anyone know if it is neccesary to recompile the rdac and if
so, is there a comprehensive lustre howto on how to compile kernel
modules.
I thank you in advance for any help
