•a two second pause

•another series of blinks providing more detailed information for technical personnel.

•a four-second pause

•the blink code sequence will repeat from step 1 until the error is cleared.

In general, any fault will require notification of Diamond Array technical personnel for resolution or for further debug instructions. When you report 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. These error messages should be reported to technical personnel to assist in debugging the problem.

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.

Disk drive activity and disk fault LEDs Each dual disk drive sled assembly contains two green activity LEDs and an amber Disk Fault LED. Once the system has successfully powered up and passed POST, the green activity LEDs are full on and the Disk Fault LED off.

The Drive 1 and Drive 2 activity LEDs will stay full on when the system is operational and no disk

drive activity is present. As the disk drives are accessed, the green LEDs will flash. If the disk drives are heavily accessed the green activity LEDs will appear to flash at a high rate or may even appear to be completely turned off.

The amber Disk Fault LED will be off under normal operation. If either of the disk drives on a dual disk drive assembly reports a disk error of any kind, the amber Disk Fault LED will come on. The Disk Fault LED can be activated by minor issues such as a disk drive writing to a bad sector (which is usually corrected by the disk drive the next time it writes) or major issues such as a head crash or complete drive failure.

When the Disk Fault LED is turned on, the system will issue a detailed message via the CLI. These messages are not written permanently to the error log file but should be recorded to help assess the disk problem.

If the disk drive error is a non fatal error and the drive is still functional, the array will continue to read and write data to the disk drive but the Disk Fault LED will remain on. If you repeat a drive command or action and it completes successfully, the Disk Fault LED may have been set by an anomaly in the disk drive. You can clear the Disk Fault LED by either power cycling the array or issuing the SledFaultLED command in CLI as per Diagnostic Commands on page 41

If you repeat a disk command or action and the Disk Fault LED remains on, the disk error may be serious. You should write down the error message issued by the CLI and contact technical support via the means easiest for you for assistance (refer to Contact ATTO Technology, Inc. on page viii). If you choose to replace the suspected faulty dual disk drive sled assembly, follow the appropriate procedures.
