Fedora 14 installation unable to format

[Steffen Maier]

Hi Clark,

could it be that the ECKD DASDs contain some existing broken Linux Disk 
Layout leading to the I/O errors? If so, I'd recommend performing a new 
manual low-level format of those disks. Since anaconda does not support 
this, you could do so manually from within any Linux on System z 
instance having access to the affected DASDs using the dasdfmt tool 
(preferably specifying Compatible Disk Layout), even using the root 
shell within the rescue mode of the Fedora installer image

http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/ap-rescuemode.html#Rescue_Mode-x86.
Dasdfmt is documented in the device drivers book

http://public.dhe.ibm.com/software/dw/linux390/docu/l26fdd00.pdf

As already suggested you could also perform the low-level format with 
z/VM tools.

FYI and not related to the I/O errors: according to the z/VM "CP 
Commands and Utilities Reference" and your device number query (which 
corresponds to the output format of CP QUERY VIRTUAL DASD), you seem to 
have in-memory VDISKs which are FBA (9336) on devno 0300 and 0301. 
AFAIK, anaconda does not handle FBA DASDs, see also 
https://bugzilla.redhat.com/show_bug.cgi?id=601855 and 
https://bugzilla.redhat.com/show_bug.cgi?id=707026.
