[Bug 1286047] Re: Ubuntu 13.10 not booting on hardware RAID

[Hag K]

Question: Did the raid array show up as /dev/sda, or /dev/mapper/something?
Answer: No it did not show as neither of those since a boot takes me right back to the UEFI/ BIOS user interface as if there is no OS installed on the RAID disk. Though, within the UEFI/ BIOS user interface I can see the RAID disk. Also note that the Ubuntu 13.10 installer can see the RAID disk and seems to install successfully.

Question: Can you run the boot info script and provide the results?
Answer: No, since it doesn't boot Ubuntu at all. The machine boot takes me to the UEFI/ BIOS interface. Installing Ubuntu on an USB Stick and then running the "bootinforscript" from there is currently not an option since I have Ubuntu 14.04 Beta1 (i.e. "ubuntu-gnome-14.04-beta1-desktop-amd64.iso") currently working on this machine for OpenStack testing purposes. Therefore the boot record entries present there now are not relevant.

Question: Also please provide a more detailed description of how the boot "doesn't work". Do you get the grub menu? Do you get an error message?
Answer: I do not get a Grub menu but instead I end up in the UEFI/ BIOS user interface. I never get to see an error message.

Note: The problem is not encountered with Ubuntu Gnome 14.04 Beta1
Desktop. I do not need this addressed with Ubuntu 13.10 but it would be
great if it works with Ubuntu 14.04 LTS as it currently does with Ubuntu
Gnome 14.04 Beta1"

Title:
  Ubuntu 13.10 not booting on hardware RAID

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  Steps to reproduce with Ubuntu 13.10:

  1. Setup the adaptec RAID controller to use ANY of the RAID modes
  2. Install Ubuntu 13.10 (in my case from USB) by using either classic partitioning or LVM
  -> Observe that the installer correctly finds the RAID disk and the installation process finishes successfully
  3. Boot the system
  -> Bug: System does not boot into the newly installed Ubuntu 13.10

  Hardware:
  - ASUS H87I-PLUS Motherboard with latest UEFI/BIOS update
  - Adaptec RAID 6405 Controller

  Note the issue reported here is not encountered with Ubuntu 14.04
  daily build (downloaded 27/02/2014). So it appears that Grub 2.02 used
  with Ubuntu 14.04 has a positive impact as it resolves the bug. I hope
  this will be another good reason to ship Grub 2.02 with Ubuntu 14.04
  LTS.
