[Bug 1677385] Re: Grub boot loader didn't install so OS not able to boot up after installation with multipath enable

[ChristianEhrhardt]

Hi,
thank you for your bug report and your help to make Ubuntu better.

I wanted to compare exact HW specs as this seems to be very HW specific,
so to make sure your issue is on UCS-S3260-DHBA IT-HBA as in [1]?

My Cisco products knowledge could be too bad, but the CSC-C3X60-HBA
seems to be a Node to be plugged into a UCS-S3260 as in [2], that sounds
wrong (and I assume my search is). If you'd have the right product for
your case you referred working with 16.04 that would be kind.

Do you have a way to get into the installation prior to (the failing) reboot?
It might be interesting to get some logs from there.
Feel free to add what you consider important, but actually on the install nothing is confidential so you could just tar up all in /var/log of the install environment.

If there is anything reasonable on the install console feel free to add
that as well.

And since we are talking about multipath issues with mp while installing
maybe a "multipath -v3 -ll" from the good and the bad system to compare
the disk/controllers as they were detected could help a lot.

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.
