** Description changed:
- During installation, either through the menu or in an ssh session ,
- dasdfmt fails with a buffer overflow error and does not format the dasd
- volume. The volume is a z/VM minidisk - defined as 1 to end, this is
- common in this environment. The DASD volume was formatted from z/VM as a
- minidisk volume. These are the same steps taken for other distributions
- running under z/VM. I've attached some screen shots.
+ [Impact]
+
+ * In certain hardware configurations, dasdfmt fails to format a drive,
+ thus preventing successful installation and/or initialisation of a new
+ disk.
+
+ "there is a bug in the parsing of /proc/dasd/devices which is being
+ triggered only if an FBA device is listed prior to the ECKD device in
+ question. And since you've had FBA devices attached to your system
+ during the installation, you ran into that bug."
