The parted utility in Red Hat Enterprise Linux 6 cannot handle Extended Address Volumes (EAV) Direct Access Storage Devices (DASD) that have more than 65535 cylinders. Consequently, EAV DASD drives cannot be partitioned using parted, and installation on EAV DASD drives will fail. To work around this issue, complete the installation on a non EAV DASD drive, then add the EAV device after the installation using the tools provided in the s390-utils package.
