4.0 Accessing the Diamond-VT
Communicate with the Diamond-VT 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-VT 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
Diamond-VT and use the Command Line
Interface or ATTO ExpressNAV, an integrated
user management console.
Command Line Interface
The Command Line Interface provides access to
the Diamond-VT 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
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 23 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 Diamond-VT 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 Diamond-VT 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. Change these
parameters using the RS-232 port or Telnet. The
Diamond-VT should first be configured for the
network using the RS-232 port to establish the
correct IP address.
