ATTO Technology Inc. Diamond Storage Array Installation and Operation Manual
4.0 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 or ATTO ExpressNAV,
an integrated user
management console
.
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 following chapters describe how to access the
array and use the Command Line Interface or
ATTO ExpressNAV, an integrated user
management console.
Command Line Interface
The CLI provides access to the array through
ASCII command lines.
An initial display, after powering up the unit or
restarting the firmware, contains the information
in Exhibit 4.0-1. Once the initial display is
complete, with the word
Ready
, you are in the
CLI 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 on the program.
In-band SCSI over Fibre Channel
In-band SCSI commands (
Write Buffer
and
Read
Buffer
) may be issued to the array 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.
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 255.255.0.0. To change the
defaults, first be configure the array for the
network using the RS-232 port to establish the
correct IP address. The management port provides
TCP/IP-based monitoring and management.
