Title:
  Grub boot loader didn't install so OS not able to boot up after
  installation with multipath enable

Status in multipath-tools package in Ubuntu:
  Incomplete

Bug description:
  On UCS-S3260-DHBA IT-HBA card with multipath enabled during the
  installation, Grub boot loader didn't seem to install on mutipath
  device so after installation it will not boot into OS. Seeing issue
  with Legacy boot install on Ubuntu 16.04/16.04.01 and UEFI
  installation was fine with multipath enabled during the installation.

  Tried installing without multipath enabled during the installation and
  it failed to install after choosing the drive.

  Ubuntu 14.04.05 with multipath enabled during the installation on this
  UCS-S3260-DHBA IT-HBA controller was fine.

  Ubuntu 16.04/16.04.01 with multipath enabled during the install on
  CSC-C3X60-HBA IT-HBA controller was fine as well. So we are expecting
  it should work on UCS-S3260-DHBA IT-HBA controller.

  As of now, on UCS-S3260-DHBA IT-HBA controller, user has to install
  regular OS install without editing "install disk-
  detect/multipath/enable=true" at installer prompt.
