What must be true before a port can be disassociated from an FA emulation on a PowerMax?
On a PowerMax, disassociating a port from a front-end (FA) emulation changes the emulation's port-mapping configuration, and because this is an emulation-level operation, Dell requires that every port currently associated with that FA emulation be taken offline before any port can be disassociated from it, rather than requiring only the target port or every port on the physical I/O module to be offline.
