[Chris J Arges]

Hello bugproxy, or anyone else affected,

Accepted powerpc-ibm-utils into trusty-proposed. The package will build
now and be available at https://launchpad.net/ubuntu/+source/powerpc-
ibm-utils/1.2.26-1~14.04.2 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Title:
  ISST-LTE: Multipath disk is not automatically set as 1st boot device
  after installation

Status in powerpc-ibm-utils package in Ubuntu:
  Fix Released
Status in powerpc-ibm-utils source package in Trusty:
  Fix Committed
Status in powerpc-ibm-utils source package in Vivid:
  Fix Committed

Bug description:
  [Impact]
  Users who have multipath devices enabled may find that powerpc-ibm-utils does not successfully map multipath devices to the proper underlying device (dm-*), and thus the correct disk may not be set for booting after installation.

  [Test case]
  Install Ubuntu on a POWER system with multipath disks, and multipath support enabled, using the following command-line option at boot:
  disk-detect/multipath/enable=true

  [Regression Potential]
  This will change the detected drive to be used for booting during the installation process and when updating grub for booting the system. Since ofdisk did not correctly map the device at all to anything meaningful if the failure case is met, the potential for regression is minimal.


  == Comment: #11 - Gary M. Gaydos <gmgaydos at us.ibm.com> - 2015-09-29 14:37:05 ==
  Steps to reproduce:

  Install 15.10 beta 1 ppc little endian using multipath disks (in this case mpatha)
  After the installation is finished no device is set as the first boot device.

  The symptom is the same as launchpad bug 1486022 against 14.04.3.
  Syslog from 1486022 and this bug are different however.  In 1486022 no
  mpath devices are found.  In this bug mpath2a (the installation
  target) has an unknown device type, and the volume group is not found.

  Here's a snippet from the syslog

  cat syslog |grep -a2 -b2 mpatha2
