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 installation.
Here is the error which i am getting:

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)

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.
