Dave,

Please check if you've got the dasd_diag_mod and/or dasd_fba_mod kernel
module loaded.
The dasd_diag_mod module allows you fast access to CMS reserved disks via
the diagnose driver,
or the dasd_fba_mod module lets you use fba type devices like the
dasd_eckd_mod module lets
you talk to 3390s.
