ATTO Technology Inc. Diamond Storage Array Installation and Operation Manual
5.0 Accessing the Array
Communicate with the Diamond Storage Array through the Fibre Channel link, the RS-232 port or the
Ethernet port using Command Line Interface commands.
You may configure and tune the Diamond Storage
Array for different environments and
applications, update the firmware, monitor
internal power and temperature status, report on
hardware diagnostics and log failures.
Three avenues are available
• In-band SCSI over Fibre Channel and over SCSI
• RS-232 port
• Telnet and SNMP over Ethernet
The rest of this manual describes how to access
the array and use the Command Line Interface or
the ExpressNAV interface.
Command Line Interface
The Command Line Interface provides access to
the array through ASCII command lines.
An initial display, after powering up the unit or
restarting the firmware, will contain the
information in Exhibit 5.0-1. Once the initial
display is complete, with the word
Ready, you are
in the Command Line Interface mode.
Type Help to display a list of all commands
available.
ATTO ExpressNAV
ATTO ExpressNAV is an integrated configuration
tool accessible through an Ethernet connection.
Platform independent, ExpressNAV contains all
the current capabilities of the CLI in a user-
friendly GUI console. A menu on each page
provides access to information and configuration
operations.
Refer to ATTO ExpressNAV: Browser-based Interface
on page 25 for more information.
In-band SCSI over Fibre Channel
In-band SCSI commands (
Write Buffer and Read
Buffer ) may be issued to the array Fibre Channel
port to manage configuration via two mechanisms
• In-band CLI over SCSI, where ASCII CLI
commands, may be issued via Write Buffer. All
CLI commands except Zmodem are supported.
• ID/value, where the application program uses a
SCSI CDB (command descriptor block) to select
the buffer ID of the configuration parameters to
be affected, and the new value of the parameter.
Most configuration options are available.
RS-232 port
The array provides remote service operations over
the RS-232 serial port using standard terminal
emulation software available with most systems.
You will need to set the following serial
parameters in your terminal program
• Bits per second: 115200
• Data Bits: 8
• Parity: None
• Stop Bits: 1
• Flow Control: None.
• Terminal type: ASCII
• Echo: on
Ethernet port
The 10/100 BaseT Ethernet port provides Telnet-
or SNMP-based monitoring and management.
The default IP address is 10.0.0.1; the default
subnet mask is 255.255.255.0. These parameters
can be changed using the RS-232 port or Telnet.
The array should first be configured for the
network using the RS-232 port to establish the
correct IP address.
SNMP, or Simple Network Management
Protocol, is an application layer protocol that
allows network devices to exchange management
information. Through a combination of standard
and custom MIBs (Management Information
Base), the array provides status and error
indications to an SNMP server, allowing the array
to be managed with other devices in a complex
