DSTAT is actually reading the ID information off the drive. The difference
between SYSGEN and DSTAT does not matter, though many people alter SYSGEN
after the fact with the correct ID so it is in sync with reality. In
configuring disk drives in SYSGEN, the only thing that really matters is
that you get the correct driver. On your system there are only two, one for
FW and one for SE. So choosing ANY FW drive would have worked.
