Analyzing condition reports
Analyzing each error condition report involves three steps:
1. Identifying the element.
2. Determining the major problem.
3. Defining additional problem information.
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 controller 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 drive 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 1B, 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 group members using the enclosure address bus. Information from enclosures
in other reporting groups is ignored.
