HP P2000 G3 SAS MSA System User Guide 41
5 Connecting to the controller CLI port
Device description
P2000 G3 MSA System controllers feature a new command-line interface (CLI) port used to cable directly
to the controller and initially set IP addresses, or perform other configuration tasks. This port differs from
G1 and G2 controllers. It employs a mini-USB Type B form factor, and requires a new cable and additional
support so that a server or other computer running a Linux or Windows operating system can recognize the
controller enclosure as a connected device. Without this support, the computer might not recognize that a
new device is connected or might not be able to communicate with it. For Linux computers, no new driver
files are needed, but a Linux configuration file must be created or modified.
For Windows computers, a special device driver, gserial.inf, must be downloaded from a CD or HP
website, and installed on the computer that will be cabled directly to the controller’s CLI port.
NOTE: Directly cabling to the CLI port is an out-of-band connection because it communicates outside the
data paths used to transfer information from a computer or network to the controller enclosure.
An in-band connection can also be used to configure a new controller. If used, cabling to the CLI port
might not be necessary. The in-band method uses the MSA Device Discovery utility on the Software
Support/Documentation CD that is included with your system, and is the best way to discover the
controller’s IP addresses automatically, so that you can use them to log into and manage your controllers
using a web browser for SMU, or telnet for the CLI. See Using the MSA Device Discovery Tool to discover
controller’s IP addresses for instructions about how to use the MSA Device Discovery Tool over your existing
in-band connection to discover controller IP addresses without using the CLI port.
Preparing a Linux computer before cabling to the CLI port
Although Linux operating systems do not require installation of a device driver, certain parameters must be
provided during driver loading to enable recognition of the P2000 G3 MSA System controller enclosures.
To load the Linux device driver with the correct parameters, the following command is required:
modprobe usbserial vendor=0x210c product=0xa4a7 use_acm=1
Optionally, the information can be incorporated into the /etc/modules.conf file.
Downloading a device driver for Windows computers
A Windows USB device driver download is provided for communicating directly with the controller’s CLI
port using a USB cable to connect the controller enclosure and the computer. If you use the MSA Device
Discovery Tool you may not need the download. However, you can download it and install it for future use.
NOTE: Access the download from your HP MSA products page at http://www.hp.com/go/p2000.
Select Models — select your product — select HP Support & Drivers, then select Download drivers and

The USB device driver is also available from the P2000 G3 Software Support/Documentation CD that
shipped with your product.
Obtaining IP values
Using the MSA Device Discovery Tool to discover controller’s IP addresses
The MSA Device Discovery Tool provides the optimal approach for setting network port IP addresses on
Windows or Linux platforms. For help with configuring your P2000 G3 MSA System products, see the
P2000 G3 Software Support/Documentation CD that shipped with your product.
