But I'm surprised that STRASPBAL *USAGE is ignore on the
guested LPAR. That must mean that the guested i OS must
somehow know it's disks are virtualized.

It's not so much ignored as there usually is next to no
performance delta between the virtual disks and so there is
nothing to do. You can run TRCASPBAL and STRASPBAL *USAGE to
attempt to move things around, but chances are not much will
happen.

Virtual disks do have a unique 4-character identifier so the
system knows the drives are virtual.
