During autoconfig, DPM systems currently configures DASD devices twice:
once for dasd-eckd and once for dasd-fba. Because the firmware
configuration file does not provide the DASD type, this can lead
to inconsistent and redundant configurations.
For example, lszdev may show two devices with the same ID:
TYPE ID ON PERS NAMES
dasd-eckd 0.0.f001 yes auto dasda
dasd-fba 0.0.f001 no auto
However, only dasd-eckd is actually present on the machine, and
the dasd-fba entry is incorrect.
Modify this configuration logic to determine the DASD type dynamically
by parsing the modalias for each device-ID, and configures only the
correct dasd-type. The resulting lszdev output accurately reflects
the actual DASD devices present.
