Yeah. That all turned out to be a bug in the HAL that we fixed
sometime during Leopard's life-span (10.5.3 I think). The only work-
around is to not use private aggregate devices and use a public one
instead.

We have developed code to create internal Aggregate Devices in our

The code now works great on Leopard and Snow Leopard but
unfortunately fails on Tiger with the error described in an old 2006

Is there any workaround for it on Tiger?
Thanks Jeff, it fixed the problem.
Another question : I guess it does not make really sense to
"aggregate" devices that are themselves... aggregate devices, so I
guess we should check to be sure to aggregate only "real" devices right?
Thanks.
