The purpose of this document is to describe how the 7-segment display on the RAID controller module works for a Sun Storage[TM] 6180, 6580 and 6780 arrays.  Additionally, it will describe the codes that can be displayed.

Goal

On boot, the array controllers will go through a rapid sequence of displays, which indicate the points in the boot up sequence that the controllers are performing. This document is intended to describe the dynamic display pattern, which is repeated if the boot up sequence stops.

Solution

Steps to Follow

Review the use cases below to get detail on the codes being shown on the display.

Step 1. Watch the 7-segment display for a repeating pattern.

The display indicates the reason why the boot sequence is stopped, and will be accompanied by an Amber Fault LED next to the display that indicates that the controller is offline as well.

The array will repeat this pattern until the issue is resolved. The pattern that is shown is the first issue that the array discovered on boot. The repeating pattern has the following general format:

category code 1+ dash+ detail code 1+ dash+ 
category code 2+ dash+ detail code 2+ dash+ 
  :
  :
category code N+ dash+ detail code N+ blank-

• The display will show a minimum of 2 category/detail codes before repeating.
• The first code will be either an SE, OS, OE, or dE category code, followed by the detail.
• A dash is identified by only the middle segment of the display lit.
• A blank is identified by no segment of the display lit.
• The "+" sign denotes Diagnostic Light (between the two 7-segment digits) is on. The "-" sign denotes Diagnostic Light is off.

• The number "5" and the letter "S" look the same in the display.
• A Start-Up Error (SE) is state produced by power on of the controller, either by insertion or power on of the module
• An Operational Error (OE) is an state produced after the controller was operational/online, but was placed offline by the subsystem.
• An Operational State (OS) is a state produced after the controller is online, and typically allows the controller to continue operations in a degraded state with some exceptions.
• A Diagnostic Error (dE) is a state produced during a diagnostic test of the controller by the subsystem which results in a component fault.

Step 2. Compare the pattern to the use cases in Table 1 and any lockdown codes to Table 2.

Table 1: Use Case Patterns

Table 2: Controller Lockdown Code Descriptions

Table 3: Controller Startup Error Code Descriptions

• If the display shows the tray ID on solid. The controller is online.
• If the display shows a repeating pattern, write it down and continue to Step 3.

Step 3. You have verified that you have a fault code on the array, which will require troubleshooting.
