Connecting to the controller CLI port

Network parameters, including the IP address, subnet mask, and gateway address are displayed for

each controller.

9.

Use the ping command to verify network connectivity.
For example:

# ping 192.168.0.1 (gateway)

Info: Pinging 192.168.0.1 with 4 packets.

Success: Command completed successfully. - The remote computer responded with 4
packets.

10.

In the host computer's command window, type the following command to verify connectivity, first for

controller A and then for controller B:

ping controller-

IP-address

If you cannot access your system for at least three minutes after changing the IP address, your network

might require you to restart the Management Controller(s) using the CLI. When you restart a

Management Controller, communication with it is temporarily lost until it successfully restarts.
Type the following command to restart the management controller on both controllers:

restart mc both

11.

When you are done using the CLI, exit the emulator.

12.

Retain the new IP addresses to access and manage the controllers, using either the SMU or the CLI.

NOTE:

Using HyperTerminal with the CLI on a Microsoft Windows host:

On a host computer connected to a controller module’s mini-USB CLI port, incorrect command syntax in a

HyperTerminal session can cause the CLI to hang. To avoid this problem, use correct syntax, use a different

terminal emulator, or connect to the CLI using telnet rather than the mini-USB cable.
Be sure to close the HyperTerminal session before shutting down the controller or restarting its Management

Controller. Otherwise, the host’s CPU cycles may rise unacceptably.

If communication with the CLI is disrupted when using an out-of-band cable connection, communication

can sometimes be restored by disconnecting and reattaching the mini-USB cable as described in

step 2

on

page 38.
The USB device driver is accessible from the Software Support and Documentation CD that shipped with

your product. The USB device driver is also available as a download.

NOTE:

Using the CLI port and cable—known issues on Windows

When using the CLI port and cable for setting controller IP addresses, be aware of the following known

issues on Microsoft Windows platforms.

Problem

On Windows operating systems, the USB CLI port may encounter issues preventing the terminal emulator

from reconnecting to storage after the Management Controller (MC) restarts or the USB cable is unplugged

and reconnected.

Workaround

Follow these steps when using the mini-USB cable and USB Type B CLI port to communicate out-of-band

between the host and controller module for setting network port IP addresses.
To create a new connection or open an existing connection (HyperTerminal):

1.

From the Windows Control Panel, select Device Manager.
