(N.B.: This driver package and these instructions are provided as is and are not supported by Dell.) To get proper drive information using OMSA 6.5 on an R510 with the H700 controller under Debian Squeeze using the stock kernel, you will need a megaraid_sas driver newer than what is in the stock kernel (as of 2012.02.01). In this directory is a .deb that uses dkms to build and install a newer driver. You will first need to install the dkms package from the Debian repository. Alternatively, this is how the .deb in this directory was built: 1) Install the dkms and debhelper packages from the Debian repo. 2) Install the linux headers Debian package for your kernel (probably use "linux-headers-2.6-amd64"). 3) Go to support.dell.com, lookup your system by the Dell service tag number, and go to "Drivers and Downloads". Select RHEL5 as your OS, select "SAS RAID", and choose "Dell Driver". Download the tar.gz file (should be called "R282636-megaraid_sas-00.00.04.31.2-1.tar.gz"). 4) Extract the tarball. Inside is a tarball called "megaraid_sas-v00.00.04.31.2-src.tgz". Rename the directory to megaraid-sas-00.00.04.31.2. Edit megaraid-sas-00.00.04.31.2/dkms.conf so that the PACKAGE_NAME/PACKAGE_VERSION lines are replaced with this: AUTOINSTALL=yes PACKAGE_NAME="megaraid-sas" PACKAGE_VERSION=00.00.04.31.2 5) Place megaraid-sas-00.00.04.31.2/ into /usr/src now that you've made the changes in the previous step. 6) Follow the standard dkms steps: "dkms add", "dkms build", and "dkms mkdeb". You'll need to use the proper invocations with the appropriate -m and -v switches. 7) Install the .deb that was created by dkms mkdeb. The output of dkms mkdeb will tell you where the .deb has been placed.
