Opening a new Feature Request as per https://bugzilla.redhat.com/show_bug.cgi?id=1144979#c4

1. Proposed title of this feature request  
Anaconda action for CDL formatting for LDL low level formatted disks. Might be possible by adding a particular parameter in kickstart?
      
3. What is the nature and description of the request?  
Red Hat only supports the CDL low level formatted disks in zlinux. The LDL formatted disks create problem during installation. kernel detects them and there partitions, whereas anaconda can't detect them. So it will be great if anaconda pop up a message with the help of dasdview output and state that there are few underlying disks with LDL format so that customers will know that there is a problem and they can fix the format.And beyond that, anaconda shall ask if customers want to fix this by CDL formatting, and if selected yes, format the Disks with CDL format.

4. Why does the customer need this? (List the business requirements here)  
This made alot of confusion about our support on CDL v/s LDL formatted disks. There are few softwares in zlinux which provides LDL formatted disks which manually need intervention to format with CDL.
      
5. How would the customer like to achieve this? (List the functional requirements here)  
By a pop up message by anaconda with few details and next steps of action, like dasdfmt with cdl format?
      
6. For each functional requirement listed, specify how Red Hat and the customer can test to confirm the requirement is successfully implemented.  
By a pop up message by anaconda with few details and next steps of action, like dasdfmt with cdl format? Or simply a pop up informational message.
      
7. Is there already an existing RFE upstream or in Red Hat Bugzilla?  
There is one _ONLY_ for warning Message https://bugzilla.redhat.com/show_bug.cgi?id=1144979

8. Does the customer have any specific timeline dependencies and which release would they like to target (i.e. RHEL5, RHEL6)?  
No
      
9. Is the sales team involved in this request and do they have any additional input?  
No
      
10. List any affected packages or components.  
Anaconda
      
11. Would the customer be able to assist in testing this functionality if implemented?  
Yes

FWIW, the same solution for 1164240 will be implemented here: 
clearpart will get a new option added to it to format LDL disks -> CDL
Comment 3 Jan Stodola 2015-10-08 18:29:04 UTC 
Retested with python-blivet-0.61.15.34-1.el7, but also FBA DASDs are treated as LDL disks, which is not correct.
Since also other LDL bugs have been moved to 7.3 and this bug is not a blocker, proposing this bug for 7.3 and moving back to ASSIGNED.
Comment 7 Jan Stodola 2016-05-12 12:03:56 UTC 
Anaconda still asks to format FBA devices, the following change is needed to fix that:

diff --git a/blivet/devicelibs/dasd.py b/blivet/devicelibs/dasd.py
index 5b5f64f..446908a 100644
--- a/blivet/devicelibs/dasd.py
+++ b/blivet/devicelibs/dasd.py
@@ -131,7 +131,7 @@ def is_ldl_dasd(device):
         return False
 
     # check we're not on an FBA DASD, since dasdfmt can't run on them
-    if arg.type[0:2] == 'FBA':
+    if arg.type[0:3] == 'FBA':
         return False
 
     # check DASD volume label; "VOL1" is CDL formatted DASD, won't

Tested with python-blivet-0.61.15.45-1.el7
Comment 10 Jan Stodola 2016-08-29 09:23:24 UTC 
Anaconda no longer asks to format FBA disks, and detection and formatting of LDL disks works fine - tried in text and vnc mode, kickstart and manual installation.
Tested with anaconda-21.48.22.86-1.el7, pykickstart-1.99.66.10-1.el7, python-blivet-0.61.15.55-1.el7.

Thanks, moving to VERIFIED.
