Troubleshooting and
Problem Solving

4.1 Overview

The RS-0800-LVD 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 Enclosure Services Processor is housed on the enclosure backplane, with the ESI/Ops Panel LEDs
on the front of the enclosure.

If a fault is indicated on the Operator Panel (ESI/Ops Panel), please refer firstly to

Table 4–2

and then to

the section referenced within that table.

4.1.1 Initial Start-up Problems

4.1.1.1

Faulty Cords

First check that you have wired up the subsystem correctly. Then, if:

• cords are missing or damaged
• plugs are incorrect

• cords are too short

Call your supplier for a replacement.

4.1.1.2

Computer Doesn’t Recognize the RS-0800-LVD Subsystem

1

Check that the Ultra-320 SCSI interface cables from the RS-0800-LVD enclosure to the host computer
are fitted correctly.

2

Check the SCSI ID settings on your RS-0800-LVD subsystem and on your system host.

3

Check that the LEDs on all installed drive carrier modules are illuminated Green. Note that the drive LEDs
will not be lit during drive spinup.

4

Check that all drive carrier modules have been correctly installed.
