One more thing that bubbled up...
I seem to remember having really weird drive problems
that were related to a mis-behaving smcX device. After
a library reconfig, we had to destroy and rebuild the
smc0 device, the destroy and rebuild the drives and
library definition in ADSM.
Just a shot in the dark at this point, but maybe that
might help.
Cheers,
Dan
