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.
