[Bug 1416001] Re: ISST-LTE: ubuntu15.04 installer is missing ibmvfc driver


The kernel packages in -proposed solves the problem.
The ibmvfc module is present on scsi-modules for both trusty and utopic.

        3.13.0-49.81	 proposed (main)

	$ wget -q http://ports.ubuntu.com/ubuntu-ports/pool/main/l/linux/scsi-modules-3.13.0-49-generic-di_3.13.0-49.81_ppc64el.udeb -O scsi-modules.udeb && ar p scsi-modules.udeb data.tar.xz | tar tJ | grep ibmvfc

        3.16.0-34.45	 proposed (main)
	$ wget -q http://ports.ubuntu.com/ubuntu-ports/pool/main/l/linux/scsi-modules-3.16.0-34-generic-di_3.16.0-34.45_ppc64el.udeb -O scsi-modules.udeb && ar p scsi-modules.udeb data.tar.xz | tar tJ | grep ibmvfc

  Defect Description:

  I am trying to install ubuntu15.04LE on multipath disks, but while
  installtion installer is not able to find multipath disks.

  For enabling multipath support is have set "disk-
  detect/multipath/enable=true" parameter in grub menu while

  Here is the error which i am getting:

  I have tried installing other distros and the installer is able to find the disks but ubuntu installer is giving error.

  lpar is at installation prompt, please have a look.

  I tried the Ubuntu install without multipath enabled and still hit the
  issue. So it is not related to multipath. On the "Detect disks"
  screen, I scrolled through the list of available drivers and did not
  find ibmvfc.

  The Ubuntu installer does not have the ibmvfc module.

  This is from a separate lpar, used to get the ibmvfc info for a running Ubuntu 15.04 system.

  (see attachment: modinfo ibmvfc)

  == Comment: #17 - David Heller <hellerda@xxxxxxxxxx> - 2015-01-28 14:13:46 ==
  So clearly ibmvfc is not a builtin on the ppc64el kernel.

  After poking around some more I can verify the ibmvfc.ko is missing
  from the installer initrd files -- both the netboot one and the one on
  the ISO.  I did find one installed system where the module is present
  so it's "around" but just not in the installer.

  So, I think the next step is to mirror this and request ibmvfc.ko be
  added to the installer.  The other alternative is to request that it
  get builtin all around.  Currently it's built as a module.

  Brian, is this correct?  Do we have a preference?

  Yes, ibmvfc needs to be part of the install image. I don't think it matters too much whether its a module or built in. Consistency with ibmvscsi makes sense to me.

  Thanks.  Changing the title accordingly.
