Reporting group feature
Another function of the enclosure address bus is to provide communications within a reporting group.
A Reporting Group (rG) is an HSV co ntroller pair and the associated drive enclosures. The controller
pair automatically assigns a unique (decimal) four-digit Reporting Group Number (RGN) to each EMU
on a Fibre Channel d rive enclosure.
Each of the drive enclosures on a loop pair are in one reporting group:
• All of the drive enclosures on loop pair 1, both loop 1A and loop 1 B, share a unique reporting
group number.
• All of the drive enclosures on loop pair 2, both loop 2A and loop 2B, share a unique reporting
group number.
Each EMU collects environmental information from the associated enclosure and broadcasts the
information to reporting g roup mem bers using the enclosure address bus. Information from enclosures
in other reporting groups is ignored.
