Analyzing condition reports
Analyzing e ach e
rror condition report involves three steps:
1. Identifying th
eelement.
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 HSV210 controller pair and the associated drive enclosures. The controller
pair automatically assigns a unique (decimal) four-digit Reporting Group Number (RGN) to ea ch 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 p air 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 mem bers using the enclosure a ddress bus. Information from enclosures
in other reporting groups is ignored.
Reporting group numbers
The reporting g roup number (RGN) range is 0000 through 4099, decimal.
• 0000 is res
erved for enclosures that are not part of any reporting group.
• 0001 through 0015 are RGNs reserved for use by the EMU.
• 0016 through 4095 are valid RGNs.
• 409 6 thro
ugh 4099 are invalid RGNs.
The repor
ting group numbers are displayed on the EMU alphanumeric d isplay as a pair of two-digit
displays
. These two displays are identified as rH and rL.
• Valid rH displays are in the range 00 through 40, and represent the high-order (most significant)
two digits of the RGN.
• Valid rL displays are in the range 00 through 99, and represent the low-order (least significant)
two digits of the RGN.
To view a
reporting group number:
1. Press and release the bottom push button until the alphanumeric display is rG.
2. To display the two most significant digits of the Reporting Group N u m ber, press and hold the top
push bu
tton unit the display is rH.
3. Press and release the top push button to display the first two digits of the RGN.
4. Press and release the top push button until the alphanumeric display is rH.
