10.1 Troubleshooting

The Diamond Storage Array provides a number of visual, audible and computer system-generated indicators to identify the operational status of the array. System status and error information is readily available. 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, please contact technical support.

Windows 2000 special instructions

When using Windows 2000, the New Hardware screen pops up and asks for a driver when the 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 AttoDM2k.pdf.

Error messages

System Fault LED If a serious hardware or software error occurs in the array, the System Fault LED will display a series of flashes or blink codes in a pattern.

•an initial series of blinks indicating the system problem

an error code, please provide both the first and second blink code values.

During a fault condition, more detailed information about the fault may be available via the CLI 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 will be displayed at power up if the power to the array is recycled.
