ATTO Technology Inc. Diamond Storage Array Installation and Operation Manual
10.0 System Monitoring and Reporting
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 to the end user.

RS-232 monitoring port and CLI
One tool to support a Diamond Storage Array is a
host computer with an RS-232 port and terminal
emulation software. Using this computer, you can
hook up a null modem serial cable to the RS-232
port on the Diamond Storage Array management
card and control the array via the Command Line
Interpreter (CLI) management software built into
the array. The CLI can be used to configure the
unit, modify key parameters and read back key
system information. (refer to

If the optional Ethernet management system card
has been installed, you may use the RJ45 Ethernet
port and Telnet to access the CLI software on the
Diamond Storage Array. Use the same CLI
commands or the ExpressNAV browser-based
interface to configure, modify or read key systems

Power On Self Test (POST)
Each time the Diamond Storage Array array is
powered up, it will perform a series of internal
tests called POST (Power on Self Test). The
POST sequence takes from 1 to 2 minutes to
complete.
Each time the Diamond Storage Array array is
powered up, it will perform a series of internal
tests called POST (Power on Self Test). The
POST sequence takes from 1 to 2 minutes to
complete.
The Diamond Storage Array’s LEDs will blink at
various points in the test sequence and, if the RS-
232 system management port is connected, a list
of tests and test results will scroll across the
screen. When the POST is nearly complete, all the
LEDs on the array will flash simultaneously twice
in a row. If the system is fully operational, the
various points in the test sequence and, if the RS-
232 system management port is connected, a list
of tests and test results will scroll across the
screen. When the POST is nearly complete, all the
LEDs on the array will flash simultaneously twice
in a row. If the system is fully operational, the
ready LED will be lit and the unit is available. If
the POST fails, the System Fault LED will be lit
and an error code will be flashed.

Ready LED
The Ready LED (RDY) indicates the operational
status of the Diamond Storage Array.

status of the Diamond Storage Array.
At power up, the green Diamond Array Ready
(RDY) LED is disabled until successful
completion of the POST (Power On Self Test)
indicating the array is available for normal
operation. If a host computer is hooked to either
Fibre Channel or SCSI port, the Ready LED will
momentarily blink and then stay lit if the
connection is good. If that host is rebooted, the
Ready LED will blink again and stay on once the
connection is reestablished.

Audible alarm
The Diamond Storage Array audible alarm warns
of potential problems or faults. It beeps twice at
power up to indicate it is operational and will beep
repeatedly when the System Fault (FLT) light on
the system management card is activated. The
alarm will turn off when the fault condition is
cleared or the alarm can be disabled by issuing a

Thermal monitoring
The Diamond Storage Array provides excellent
advance warning of problems in temperature
through a variety of warning mechanisms (visual,
audible and software) and through an automatic
system which protects the disk drives under
abnormal operating or ambient conditions.
