My FBA device was not picked up because the fba part of the dasd driver was not in the initrd (argh! - that rules out install from a 'iso-as-if-a-3370' install type on the P390). The other part I think is because the disk was CMS formatted before I started and there may be two different code paths trying to tell if the disk is managed by the ECKD or the DIAG portion, and one of these decide the other portion should handle it (and DIAG is not in either). I'm sure I will have plenty of options to repeat the process ;-) Rob
