With this fix you can format a DASD that was used for LVM.

I have however found a problem, of which I don't know if this is related
or a new one or is even expected behaviour. If this is separate, please
tell me so that I can open a new bug for this.

Here's what I tried:

- Select DASD (which I used for an installation with LVM before)
- Format the Device -> no
- Finish
- Partitioning method: manual

- Menu "Partition disks":
DASD 0.0.5d32 (ECKD) - 7.4 GB IBM S390 DASD drive
>     #1    500.0 MB       ext2
>     #2      6.9 GB    K  lvm
>            49.2 kB       FREE SPACE
LVM VG rootVG, LV rootLV - 6.9 GB Linux device-mapper (linear)
>     #1      6.9 GB       ext4

- Go Back

- Select "Configure direct access storage devices (DASD)"

- Select previous DASD again; DASD is displayed as 0.0.5d32 (online)

- Format the device -> Yes

- Error:

Installation step failed
An installation step failed. You can try to run the failing item again from the menu, or skip it and choose something
else. The failing step is: Configure direct access storage devices (DASD)

/proc/partitions looks like this:

1        1      40000 ram1

I have attached the syslog that was created during my test.

Title:
  Installer cannot use DASD if it was used with LVM before

Status in lvm2 package in Ubuntu:
  Fix Released

Bug description:
  == Comment: #0 - Michael Roesch <ROESCH3 at de.ibm.com> - 2016-01-21 07:31:16 ==
  A DASD that has been used with and partitioned for LVM, cannot be used for installation. The installer cannot format the disk. It throws the error "An installation step failed. You can try to run the failing item again from the menu, or skip it and choose something else. The failing step is: Configure direct access storage devices (DASD)". 
  When you just select the DASD without formatting, the installer accepts the DASD, but hangs at "Scanning disks..." at 45 percent. I have attached the syslog.
