About this guide
1 Data Path Module management interface options There are two ways to interface with the Data Path Module (DPM): • Over a serial connection using the DPM management command line interface (CLI) • Over an IP connection using the DPM management graphical user interface (GUI) Most activity with the DPM GUI occurs during initial configuration and debugging (when requested by HP Support). Therefore, under normal operation, the DPM GUI is seldom used.
Data Path Module management interface options
2 Using the command line interface This chapter describes the use of the HP StorageWorks SAN Virtualization Services Platform Data Path Module (DPM) command line interface (CLI). You can configure and manage the DPM with these common command sets that provide the same functions as the DPM GUI. CLI overview The DPM provides a command line user interface through serial, telnet, and ssh connections with serial being the preferred default.
Object type snmp date/timezone Command Page Enable user command 35 Show user command 68 Show users command 69 Create snmp command 23 Disable snmp command 29 Enable snmp command 34 Modify snmp command 44 Show snmp command 66 Modify date command 39 Modify timezone command 45 Show date command 54 Show fan command 59 Show fans command 60 Show group command 60 Show groups command 61 Show therm command 67 Show therms command 68 Show ps command 65 Show pss command 65 Show
This CLI provides command completion to minimize the typing needed to run commands. This feature enables you to press the completion key (the Tab key) to complete a partially typed command line. If the command line fragment is unambiguous, it is completed with the remainder of the command line. If there is more than one possible match for a command line fragment, continue pressing the Tab key to see each of the possible matches.
1. With a serial cable between the VSM server and the DPM, open a PuTTYtel session. Figure 1 PuTTYtel Configuration screen 2. Ensure a speed of 9600 is used with a Serial connection type, and click Open. A login screen appears.
3. Log in to the DPM with the default login and password. NOTE: HP recommends that you change the default password. If you have not already done so, run the “Modify user command” on page 46 to change the password. login: admin password: password The following menu options are displayed (see Figure 3). Figure 3 PuTTYtel console menu options 4. Enter commands from the command line to begin managing the DPM with the CLI commands.
“Modify user command” on page 46, “Modify eth command” on page 40, “Modify port command” on page 42, and “Modify ports command” on page 43 for more information.

4 Using the Data Path Module management GUI The DPM Management GUI is supported on Microsoft Windows platforms running Internet Explorer version 5 or greater. To run the DPM Management GUI, install Java WebStart on your management station. Java WebStart is an application that allows you to download and run a full-featured Java application, such as the DPM Management GUI, directly from a web page.
2. In the screen that displays, click the version for Windows, local copy to install and run the Sun Java WebStart application on your machine. 3. On the Security Warning window, click Run. NOTE: You may need to manually download and install Java 1.5 or later before installing the VSM client interface. 4. The License Agreement dialog box is displayed. In the License Agreement dialog box, click Accept to begin software installation. 5. Click Start. 6. Click Yes if you want a desktop shortcut. 7.
Downloading the DPM Management GUI NOTE: At least 100 MB of free disk space must be available on the hard drive of your host system for the DPM Management GUI and WebStart software. Install WebStart from the browser used to access the DPM Management GUI. For example, you cannot install WebStart using Netscape and run the DPM Management GUI from Internet Explorer. 1. In your web browser, type the IP address of the DPM management port, labeled MGMT (for example, http://10.0.0.1).
Logging into the DPM Management GUI 1. From a web browser, log in with the username and password, using the same web browser from which the WebStart application was installed. User name: admin Password: password Figure 5 DPM Management GUI Login screen 2. Click Login. 3. HP recommends that you change the password if you did not already do so during setup: • If you are using the DPM Management GUI, change the password on the telnet screen. See “Telnet” on page 85 for more information.
Figure 6 DPM Management GUI screen Using the DPM Management GUI, you can access these functions.
3. Click the specific port to manage. The port information screen is displayed (see Figure 7). Figure 7 System port information screen The following information is displayed for each selected port: • • • • • • • World Wide Node Name World Wide Port Name State of link (enabled/disabled) Mode (fabric or loop): Only fabric is supported with SVSP.
NOTE: Enabling and disabling ports takes effect immediately after clicking the Enable/Disable buttons. Disable: Click Disable to disable a port. Enable: Click Enable to enable a port. Chassis panel (system) The Chassis panel displays information about the DPM, such serial number and hardware versions. You can also set the description of the DPM and add a location comment. The DPM can also be rebooted from the Chassis panel.
Figure 9 System Ethernet panel An amber LED indicates that the corresponding component is missing, has failed, or will likely fail soon. Even if your DPMs appear to be performing normally, replace the part if the corresponding LED has turned amber. SNMP panel (system) Figure 10 shows the SNMP panel. This panel allows SNMP v2 or v3 to be enabled or disabled. A trap receiver can also be specified that will receive SNMP trap events from the DPM, if not enabled during the initial installation.
Figure 10 System SNMP panel Network Protocols panel (system) The Network Protocols panel allows the configuration of networking options on the Data Path Module. Figure 11 shows the Network Protocols panel.
Figure 11 System Networks Protocols panel NOTE: If maximum network security is required, all the settings on this panel should be turned off in normal operation, and enabled only when needed. Enable SSH: Enables Secure Shell (SSH) support in the DPM. SSH is a remote login facility (similar to telnet) with security features, including strong encryption and authentication. Use SSH as a alternative to telnet for administrative logins to the DPM.
Figure 12 System Time Base panel Software panel (system) The Software panel shows the current and backup bootset information. Figure 13 System Software panel Sensors panel (system) The Sensors panel for the System function shows diagnostic information for temperatures, fans, power supplies, and voltages for the power supplies on the Data Path Module.

Business Copy SVSP An HP StorageWorks product that works with SAN storage systems to provide local replication capabilities within the SVSP domain, providing local point-in-time (PiT) copies of data, using snapshots of data, based on changes to virtual disks. CLI Command line interface. The Data Path Module provides a CLI through the local administrative console (serial port console), telnet, or SSH.
HBA See host bus adapter. host In VSM, every server that uses VSM virtual disks. Servers that run as VSM servers are also considered hosts. host bus adapter A device that provides input/output (I/O) processing and physical connectivity between a server and a storage system.
