I have an HP Proliant DL380e with a 1TB SAS Drive and I am trying to
install ubuntu server 12.04 on it.
I have created a RAID array using Array Controller Utility and had a RAID0 logical
volume configured on that array. I also set this logical volume as the
primary bootable device.
Having done this, I believe installing ubuntu on the created partition
should be as smooth as it can be. However, it seems I am so wrong...
During the installation process, the installer does not detect my SAS
Drive. At the step required to partition disks, it only avails the option
to "Configure iSCSI Volumes".
When I checked the /var/log/syslog file. I see that the installer tries to
detect SATA Drives but finds none.
Are there any custom configurations I need to make to get the installer to
successfully detect my SAS Drive? I can't quite figure out what I need
to do get the installer to detect my SAS Drive.
Thanks in advance.

Some models of the HP ProLiant DL380e use a Dynamic Smart Array controller. This is a low-end controller and doesn't have the same widespread support as a proper Smart Array controller. The other problem here is Ubuntu... Windows, Red Hat and SuSE all have drivers for this controller. Ubuntu does not. See the HP/Ubuntu technical exceptions matrix.
The HP Dynamic Smart Array B110i/B120i/B320i controller driver for
Ubuntu 12.04 is not available. The Ubuntu 12.04 certification was
completed in SATA mode.
Ubuntu is certified for the ProLiant DL380e only if the Dynamic Smart Array controller is disabled. Please see the Ubuntu certification notes.
System is certified with Dynamic Smart Array
disabled. To disable: *Press F9 to boot into RBSU *Navigate to System
Options -> HP Dynamic Smart Array B320i and select disable *Go to
System options -> SATA Controller options and select Legacy SATA or
AHCI *Reboot the machine and now you will be able to install the OS.
It's unfortunate. The DL380e is an entry-level server. The DL380p would work properly with no modification. But the other issue is that Ubuntu doesn't have the support for the RAID controller.
