Solution  1021109.1 :   Sun StorageTek[TM] 6140, 6540, and Flexline 380 Array Controller 7-Segment LED  


PreviouslyPublishedAs

Description
The purpose of this document is to describe how the seven(7) segment display on the RAID controller module works, for a Sun StorageTek[TM] 6540, StorageTek[TM] Flexline 380, and Sun StorageTek[TM] 6140. Additionally, it will describe the codes that can be displayed.
The seven segment displays on these arrays are static.  Under optimal conditions they will display the tray ID, which is 85 by default. 

On boot, the array controllers will go through a rapid sequence of displays, which indicate the points in the boot cycle that the controllers are performing.  This document is intended to describe the static display, which does not change after the boot sequence has stopped.  The static 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.



Steps to Follow
Follow the steps below to reference the meaning of the tray ID.
1. Verify that you're looking at the RAID module or controller.

The RAID module is a piece of hardware that contains only the RAID controllers and power distribution components for the module,
pictured here in the Sun System Handbook.  This applies to a Flexline 380 and a 6540 array.

The RAID controller tray is a tray of drives that contains a pair of RAID controllers, instead of expansion modules.  The difference
being that the controllers have ethernet network ports on them.  An example is pictured here in the Sun System Handbook.  This applies to a 6140 array.

If your array is not a 6140, 6540, or Flexline 380, but has a seven segment display on the RAID controller tray or module, you
 are likely looking at a 6580, 6780, or 6180 array.  Please reference
Otherwise, continue

2.  Review the table below against what you are seeing on your display, for it's meaning. 

Code	Description
L0	The controller types are mismatched
L1	The interconnect is missing
L2	A persistent memory error has occurred.
L3	A persistent hardware error has occurred.
L4	A persistent data protection error has occurred.
L5	The auto-code synchronization (ACS) has failed.
L7	The sub-model identifier is not set or is mismatched
L8	A memory configuration error has occurred.
L9	Link speed mismatch
LF	Lock-down with limited Management access
LH	Controller firmware mismatch
LU	Controller Reboot Limit Exceeded
88	This controller is being held offline by the alternate controller
85	This is the default tray ID.  Although it can be set to anything between 85-93, it is not recommended to do so.
5d or Sd	Controller is booting its operating system
