Diamond Storage Array
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 are 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 stays full
on when the system is operational and no disk
drive activity is present. As the disk drives are
accessed, the green LEDs flashes. If the disk
drives are heavily accessed the green activity
LEDs appears to flash at a high rate or may even
appear to be completely turned off.
The amber Disk Fault LED is 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 lights. 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
issues 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 continues to read
and write data to the disk drive but the Disk Fault
LED remains 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
Warranty
on page xvi). If you choose to replace
the suspected faulty dual disk drive sled assembly,
follow the appropriate procedures.
