HP Proliant DL120 G7 Raid 1+0 and Linux

[SGE4ever]

Hello Community,

the following issue we have with one of your HP Server:

we need to install in a Raid 1+0 envirnement an Red Hat Enterprise Linux 6 Server (x86-64) OS.

the B110i SATA RAID Controller has been configured already as 1+0 via different ways.....with F8 and so on and used as well the SmartStart 8.70B DVD that gave as a few more options.....but it looks like that the Raid is configured on the Controller.

if we start now to install the Linux onto the server, we see that the install gets done only on the first HDD without pushing anything over to the second HDD. Partition getting done for example as well only on the First HDD....absolutly nothing getting written on the Second HDD.

if we use the SmartStart, we have an option to install an OS via the GUI, but all we can see is Windows Based OS and no Linux OS as we think it should, because we see in the DVD Drivers for the Linux Machines.

it almost looks like that we have the Driver for the Controller, but no Driver for Linux.

we have downloaded SATA RAID Controller Driver updates .rpm for Linux, but is that actual required to install? and if so....how exactly do we install them?

thanks for now

Udo

You need the hpahcisr driver for the RAID function of the B110i controller.  The driver for RHEL 6 and instructions for use can be found here http://h20565.www2.hpe.com/hpsc/swd/public/detail?sp4ts.oid=3958195&swItemId=MTX_f40bb4d3a183494cb4643bbedd&swEnvOid=4103

You need the dd image of the driver during boot and must add the following to the boot line 'dd blacklist=ahci'

The driver is release specific and you will need the correct driver for your version of 6.x. You may look at putting the controller in plain SATA mode and using the software RAID from the OS itself.

Hi,

we have downloaded the hpahcisr-1.2.6-18.rhel6ux.x86_64.dd.gz and extracted them into a different folder, doing so we recognized that the latest 3 updates included only a 'dd.img' file, these we renamed to there respective update name.

we copied all 6 Files into an empty USB Stick and connected the Stick to the Server.....entered the LINUX DVD and started to boot, we were then able to enter the anaconda bood menu, but were unable to get any further, because we got the following error:

dd: unregognized operand 'blacklist=ahcl'

we tried as well to run 'dd blacklist=achi', but we have gotten the same error meassge.

I guess we are making just one basic error to get successful the Driver installed, could you lead us a bit further the way?

You don't need all 6 files, you only need the one that corresponds to the update version of 6.x you are attempting to install.  From the boot menu you need to edit the boot line and append the boot options. The option 'dd' tells the installer to check for a driver disk, and the 'blacklist=' option keeps the installer from loading the ahci driver.

IF you are entering this at the 'boot:' prompt you need it to read 'linux dd balcklist=ahci'
