If you receive an error message stating No devices found to install Red Hat Enterprise Linux, then there may be an issue with your DASD devices. If you encounter this error, add the DASD=<disks> parameter to your parm file (where disks is the DASD range reserved for installation) and start the install again.

Additionally, make sure you format the DASDs using the dasdfmt command within a Linux root shell, instead of formatting the DASDs using CMS.
