CHAPTER 4: Troubleshooting
12
Overview
The Gateway E-842R enclosure includes a processor and associated monitoring and control logic
to enable it to diagnose problems within the enclosure’s power, cooling, and drive systems.
The sensors for power and cooling conditions are housed within the power supply modules. There
is independent monitoring for each unit.
If a fault is indicated on the Ops panel, see the table in “Ops panel LEDs” on page 14.
Initial start-up problems
Faulty cords
First make sure that you have wired up the subsystem correctly. Then, call Gateway Customer Care
for a replacement if:
• Cords are missing or damaged
• Plugs are incorrect
• Cords are too short
Alarm sounds on power up
See “Audible alarm” on page 15.
Green “Signal Good” LED on controller module is not lit
• Make sure that the SAS cables are properly connected.
• Try removing and re-inserting the suspect RAID controller.
• If the Fault LED is lit there are a few steps you can take to attempt to diagnose the problem:
• Connect the cable to the RS232 port and to your COM port or terminal. In your terminal
window, access the RAID Configuration Utility (RCU) and examine the event log to
determine if an event occurred. If an event is listed, refer to the VT-100 RAID
Configuration Utility User Guide for an explanation of the event. Perform the necessary
troubleshooting from known information.
• Try power cycling the enclosure while monitoring the boot process from the terminal.
Refer to the VT-100 RAID Configuration Utility User Guide - Monitor Mode.
• If you are still unable to capture and examine the boot process to determine the cause,
contact Gateway Customer Support. Refer to the VT-100 RAID Configuration Utility User
Guide.
Your computer does not recognize the enclosure
• Make sure that the interface cables from the enclosure to the host computer are connected
correctly.
• Make sure that all drive carrier modules are correctly installed and that the LEDs on all
installed drive carrier modules are lit green. Note that the drive LEDs are not be lit during
drive spinup.
• Make sure that there is activity on the SAS connector activity LEDs. Also check for Controller
OK LEDs on both the upper and lower RAID controllers.
