An LVM-partitioned DASD cannot be formatted if you have not chosen to do so on first-time selecting the DASD for installation. 

Reproduction:

- 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.
