Has anyone tried to connect the second port of an HSC50 served disk to the UDA-50 on one of the cluster vaxes? Presumably you'd need to set the allocation class the same and prey (or otherwise coerce) that the HSC50 was used as the primary path. I'm interested in this principally for robustness since we have been having trouble with our HSC50 (Circuit breaker in the back trips occasionally). -Ken Adelman Caltech
