Hello Chris

Hi from Adi

Here is a update on my findings from 15.04 PPC64LE Live image:

I tried latest driver from avago 06.809.16. Preliminary every thing
looked okay: Creating, deleting and accessing RAID0 volume.

However, coming to particular error that we are facing that: 15.04
Ubuntu Disk Install blocked on  Avago RAID Disk.  That error,from logs
and console messages,  has to do with mounting ext4 file system on Avago
Raid Disk. But as you can imagine it’s a bit hard to reproduce this full
install and debug. So I tried to reproduce that specific part of
mounting in live image with newest driver.

So basically I focussed to pin point on what’s causing that error:

a)I created a partition on raid disk (from Avago) with ext4.   
b)Tried to mount the ext4 

Doing so returns an I/O error, even in live image with Avago’s latest
driver . I pasted the commands below: and DMESG error at extreme bottom:


Procedure to reproduce this error:

To make it more simple to reproduce and debug: I booted to a Live Ubuntu
OS PPC64LE 15.04 Version:

And executed the following commands:


storcli64 /c0 /vall del force     (delete virtual disk)

storcli64 /c0 add vd type=r0 drives=252:0-3  (Create new v drive)

storcli64 /c0 /vall start init force             (Initiate the v drive)

Title:
  Ubuntu 15.04 Install Error with Avago Controller

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Hello Canonical Team

  We are running to an issue installing ubuntu PPC64LE 15.04 full blown
  image on our servers  (with RAID controller).  Installation hangs
  around 70% of progress.

  An important part of our configuration is Avago RAID controller:
  9361-8i Firmware version we used is 4.300.00-4429, and the package is
  24.10.0-0002.

  IMPORTANT: It has to be noted that with same hardware configuration
  14.10 full blown image installs fine.

  Dmesg logs are attached:

  Looking at dmesg logs point out that:
  LSI (avago) driver loads fine
  During further interaction with raid volume during the installation process, firmware errors are seen 
  [  196.991417] megasas: FW status 0x3

  [  196.999376] megasas: FW status 0x3

  [  197.007376] megasas: FW status 0x3
  Further down the  process I/O errors are thrown
  [  217.438664] Buffer I/O error on device sda2, logical block 22052864

  [  217.438671] Buffer I/O error on device sda2, logical block 22052865

  [  217.438678] Buffer I/O error on device sda2, logical block 22052866

  [  217.438686] Buffer I/O error on device sda2, logical block 22052867

  Full dmesg log is attached. Snippet is pasted below highlighting:

  It can be noted that there’s a Mellanox Connectx 3 pro card with some test Firmware on our setup. 
  We can Ignore any diagnostic messages from that card in dmesg logs for the purpose of this bug. 

  Thanks
  Adi Gangidi
