Solution 1004609.1 : Sun Storage Array D130: How to read panel LED's

Applies to:

Sun Netra st D130 Storage Array (DC) - Version Not Applicable and later
Sun Netra st D130 Storage Array (AC) - Version Not Applicable and later
All Platforms

Goal

This document is intended to examine and explain all the LED's and switch setting on a Sun Storage D130 Array. It will also touch on daisy chaining and termination.

The information provided here has been extracted from Netra™ st D130 Installation and Maintenance Manual

Solution

The front panel of the D130 has 6 LED's arranged in the below configuration:

D130 Array Figure 1

The System Power LED is lit when power is on and unlit when power is off.

The system summary fault LED is green when all is normal and amber when the entire D130 (minus the disk drives) needs to be replaced.

In order to explain the Disk Drive LED's the rear panel needs to be referenced:

The SCSI ID switch sets the SCSI IDs for the disk drives.

D130 Termination

System Power and System Summary Fault LEDs
The System Power and System Summary Fault LEDs give the same diagnostic
information as the System Power and System Summary Fault LEDs at the front of
the enclosure.

Auto Termination Indication LEDs
The Auto Termination Indication LEDs indicate if the Netra st D130 storage
enclosure is part of an UltraSCSI, wide SCSI or narrow SCSI daisy-chain. It also
indicates its position in the daisy-chain.

High	Low	Meaning
Off	Off	The Netra st D130 storage enclosure is the first device in the UltraSCSI or wide SCSI daisy-chain; another device follows it.
On	On	The Netra st D130 storage enclosure is the last or only device in the UltraSCSI or wide SCSI daisy-chain.
On	Off	A narrow SCSI device follows the Netra st D130 storage enclosure in the daisy-chain.
Off	On	N/A
