Bug Description

When trying to install Lucid Alpha 3 on a DELL R210 equipped with a PERC H200 SAS controller no disks are found. The installer doesn't recognize the PERC H200 card which is based on the mpt2sas driver.

I'll add the information from the installer tomorrow as requested.

1) uname -a > uname-a.log
2) cat /proc/version_signature > version.log
3) dmesg > dmesg.log
4) sudo lspci -vnvn > lspci-vnvn.log

Had the same issue while installing ubuntu 9.10 server (from the netinstall CD) on a R710 dell poweredge (also using perc H200 controler -so I needed the mpt2sas module)

satriaNIC: How did you solve your problem did you open and include the mpt2sas in the ISO cd? OR is the server running something else

Having the same problem with debian, it might not be ubuntu related. I have checked all the scsi*.udev packages and so far failed to find the mpt2sas.
Solution I used was to extract the /lib/modules/<kernelversion>/kernel/drivers/scsi/mpt2sas/* and place them in the initrd.gz file.

Note: I use PXE booting so changing the initrd file was relatively quick.
Note: last installer checked used kernel 2.6.30

Driver is still missing in Lucid 10.4 Beta 1 with kernel 2.6.32-16-generic

Lucid can't be installed on new DELL servers.

I have the same problem with the Ubuntu-server installation.

Janåke Rönnblom (jan-ake) wrote :

Three solutions for running Linux on your new server:

1. Install another linuxdistribution from a leading vendor ;)
2. Sell the server on ebay and buy another with support for Ubuntu.
3. Do like this:

1. Boot from the installcd
2. Go to one of the console (alt+f2)
3. Insert USB key with driver on it. (mount -t vfat /dev/sda /mnt --> or something like that)
4. Copy the required driver to /tmp (otherwise the usb i /dev/sda which is where we want the disks from the RAID card)
5. Unmount the USB key6
6. insmod the mpt2sas driver from /tmp
7. Go into the install menu and detect the disks again.
9. After install replace the generic kernel with the server kernel

The driver can be found in the generic kernel. I did install a virtual machine and then installed the generic kernel to it (afterwards) so I could get my hands on the mpt2sas driver.

Hi janake. I'm reading that you resolve the problem!

- Point 1
Must I start the installation with ubuntu-server or ubuntu desktop?
- Point 3
Could you link or upload the driver (zip file) that I must add in USB key?
- Point 6
I must to run the command >insmod /tmp/mpt2sas(folder or file)
- Point 9
I don't understand this point.

So, in which version of Ubuntu this bug was/will fixed?

I'm reading that the ubuntu 10.04 includes the 2.6.32-16.25 kernel based on and NOT the 2.6.32-21.31.

Should I attend a next beta?

includes so it should work...
Or wait for the RC next week :)

Hm, sorry, the daily is still at 2.6.32-20.30, maybe tomorrow.

Can anyone advise if there is an iso image (i386 server) for Lucid that now has the mpt2sas modules in - trying to install on Dell R210 with no luck so far (exact problems as described above) but all images I've tried so far don't seem to work.

I have installed ubuntu 10.04 (64 bit ) without any problems or procedures!!

I follow the procedures Janåke Rönnblom on 2010-03-29 to install Ubuntu server 9.04 x86_64. Everything goes well, but in the last step, i can not build initramfs for server version successfully.

   Even i follow the manpage of mkinitramfs to modify /etc/modules & /etc/initramfs-tools/modules, it still does not work. Could you provide the detailed command to build initramfs supporting scsi_transport_sas.ko & mpt2sas.ko ?

Lin Avator (lavator) wrote :

Eventually, i try out to vi lib/modules/2.6.28-11-server/modules.order in initrd.img-xxx to add support for mpt2sas, and then re-package initrd.img-xxx. It works now.


jfabrizio (jfabrizio84) wrote :

I resolved this problem in the following way:
1) I have installed the daily ISO ubuntu desktop (as suggest from Thierry Carrez) in normal way (this version recognizes the PERC controller)
2) I have installed the ubuntu-server package.

So, my dell-ubuntu server works perfectly!!

Glad to see that the bug has been fixed.
JFabrizio, can you please help me out ? Which version of Ubuntu desktop did you install ? 32 or 64 bits ?
Did you disable anything in the bios ? When did you configure the RAID ?

I have the 2.6.32-24 (Ubuntu 10.04.1 x64), which contains /lib/modules/2.6.32-24-generic/kernel/drivers/scsi/mpt2sas - but no sure what I have to do next.
If I start the installation, it won't see the RAID.

Roger Gardner (r-gardner) wrote :

I have now have Ubuntu 10.10 x64 and there is still no easy way to get the mpt2sas driver to work on my Megaraid SAS9240. It uses megaraid_sas, which does not support automatic rebuild of Raid 1 when a drive is pulled and a new formatted drive is put in. This is a very important step for a server. If I can not get this to work, we will probably go to SLES11 with SP1 and I can look for a new job.
