Note that in the Class and State fields, the virtualization engines arepresented as
two primary/ONLINE devices. The current Sun StorEdge TrafficManager design
does not enable you to manually halt the I/O (that is, you cannot perform a failover

Alternatives to Sun StorEdge Traffic Manager
As an alternative to using Sun StorEdge TrafficManager, you can manually halt the
I/O using one of two methods: quiesce I/O and unconfigure the c2 path. These
methods are explained below.
