This screenshot shows output from hdparm, fdisk and the values in
/sys/block/sda/queue/physical_block_size and logical_block_size.

Title:
  Ubuntu 18.04 install not reading block storage properly

Status in hdparm package in Ubuntu:
  New

Bug description:
  We recently received Supermicro servers with Avago 3108 chipset, and
  2x Seagate 4K SAS drives in a hardware RAID1 configuration.

  All other operating systems (including Ubuntu 16.04) report this
  virtual drive properly.

  Ubuntu 18.04 shows it as if it were using 512 byte sectors, instead of
  the 4K sectors that are actually there.

  Instead of having ~1TB drive, it shows as ~8TB and is unable to
  install no matter what I do.

  Going to shell during install and running fdisk shows all of the right
  information and drive/sector sizes.

  I am able to install 16.04 and then upgrade to 18.04, but that is not
  ideal.

  Please let me know what other information I can get, or how I can get
  it for you.
