ATTO Technology Inc. Diamond Storage Array Installation and Operation Manual
8.1 Troubleshooting
The Diamond Storage Array provides a number of visual, audible and computer system-generated indicators to
identify the operational status of the array. If your situation is not defined here or elsewhere in the manual, if these
solutions do not help, or if you have any questions or concerns about any aspect of operating the array, contact
technical support.
Windows 2000 special instructions
When using Windows 2000, the
New Hardware
screen pops up and asks for a driver when the
Diamond Storage Array is first booted up. While
a driver is not necessary for operation, you should
install our dummy driver to eliminate the
New
Hardware screen’s appearance. Download
AttoDM2k.zip
from our website,
www.attotech.com
, unzip it, and install the driver
AttoDM2k.inf
according to the instructions in

Error Messages
System Fault LED
If a serious hardware or software error occurs in
the array, the System Fault LED displays a series
of flashes or blink codes in a pattern.
• an initial series of blinks indicating the system
problem
• a two second pause
• another series of blinks providing more detailed
information for technical personnel.
• a four-second pause
• the blink code sequence repeats from step 1
until the error is cleared.
In general, any fault requires notification of
Diamond Storage Array technical personnel for
resolution or for further debug instructions. When
you report an error code, provide the first and
second blink code values.
During a fault condition, more detailed
information about the fault may be available via
the CLI or the ExpressNAV interface over the RS-
232 interface port or the optional Ethernet port.
The blink codes are also saved internally by the
array to NVRAM (Non Volatile Random Access
Memory) and are displayed at power up if the
power to the array is recycled.

Audible Alarm
The array audible alarm warns of potential
problems or faults. It beep repeatedly when the
System Fault (FLT) light on the system
management card is activated. The alarm turns off
when the fault condition is cleared or the alarm
can be disabled by issuing a
PowerAudibleAlarm
or
AudibleAlarm
command via CLI as described in
Diagnostic
Commands
on page 41. Disabling the alarm for a
specific error does not silence the alarm for other
error conditions.
