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. Of the two interface
methods, using the serial connection is the preferred method because it more secure than using the
Internet.
This document describes the two interface methods beginning with the CLI.
HP StorageWorks SAN Virtualization Services Platform Data Path Module User Guide 9
Data Path Module management interface options10
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. All configuration, maintenance, and monitoring of the DPM is
performed through the CLI.
Command quick reference by object

Command syntax and command completion
The CLI command syntax is as follows:
command
keyword [value]
keyword [value1] [value2]
The command is followed by one or more keywords. Consider the following rules and conventions:
• Commands and keywords are case sensitive.
• Required keyword values appear in standard font: [value]. Optional keyword values are shown
in italics: [value].
Using the command line interface12
66Show voltage command
66Show voltages command
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. You then type enough of the command line to distinguish it from
the other possible matches.
In addition, you can get a list of legal fields at any point in the command line. For example, if you
type set debug p, and then press the Tab key, a list of valid debug options beginning with the
letter p is returned.
The completion feature in the CLI also validates previously typed input. If there is an error in the
command line prior to the point where you have requested completion, an error is printed and the
cursor is set to the point where the command line breaks the defined syntax rules.
Online help
The CLI for the DPM includes online help. Type part of a command, and press Enter, to view the help
information, such as a list of arguments or the proper syntax.
Help commands
For information about getting a list of commands, see “Help commands” on page 33. For information
about getting help with a particular command, see “Help command” on page 32.
Example 1.
Typing modify and pressing Enter returns these results:
required arg not present
one of [eth, ntp, snmp, factory, chassis, therm, port, ports, date, timezone,
user, san '?'] required
Example 2.
Typing show use and pressing Enter returns these results:
admin@k-> show use
show user <user name>
show users
“use” is ambiguous, must differentiate between: [user, users]
Please refer to command syntax for detail.
Accessing the CLI
The DPM management (MGMT) port is configured when the HP StorageWorks SAN Virtualization
Service Platform solution is installed on site. The following procedure describes how to use the serial
port with PuTTYtel to access the DPM CLI on the VSM server. The PuTTYtel terminal emulator is provided
on the open source CD in your media kit.
HP StorageWorks SAN Virtualization Services Platform Data Path Module User Guide 13
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.

.
Using the command line interface14
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 42 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.
Users and groups
The DPM provides two built-in users and two built-in groups: admin is a member of the Administrator
group, and kmonitor is a member of the Monitor group.
Table 2 shows the default password for both accounts. See “Modify user command” on page 42 for
information about changing the password.
NOTE:
The default passwords may have been changed prior to your installation of the DPM. See the records
of the installation for details.
Users in the Monitor group are limited to commands that only view system configuration and status;
Monitor users cannot change the system configuration. See the show commands, such as “Show user
command” on page 65, “Show port command” on page 59, and so on, for more information.
Users in the Administrator group can create and delete users, and they can also modify users, eths,
ports, and perform all of the other commands listed in this document. See “Create user
command” on page 19, “Delete user command” on page 22, “Modify user command” on page 42,
HP StorageWorks SAN Virtualization Services Platform Data Path Module User Guide 15
“Modify eth command” on page 36, “Modify port command” on page 38, and “Modify ports
command” on page 39 for more information.
Table 2 summarizes the features of the built-in groups.

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.
The DPM simplifies the task of configuring the management station by automatically detecting whether
Java WebStart needs to be installed when the management station first accesses the DPM. If Java
WebStart is not present on the management station, the DPM can provide a copy of the application
that you can download and install. See “To install Java WebStart” on page 69 and “To download
the DPM Management GUI from a Web browser” on page 71 for more information.
Once you have installed the WebStart application, the web console enables you to access the DPM
Management GUI remotely using your standard web browser. For web browsers already running
Sun's Java WebStart application, skip the next two sections and see “To log into the DPM Management
GUI” on page 72.
NOTE:
Sun Microsystems provides versions of Java WebStart for Windows and other platforms through its
Java website. You may be able to use the DPM Management GUI from non-Windows management
stations using a version of Java WebStart provided by Sun; however, HP only supports the use of the
DPM Management GUI on Windows platforms running Internet Explorer version 5 or greater in
conjunction with the version of the Java WebStart application provided with your Data Path Module.
Installing Java WebStart
For web browsers on Windows platforms that are already running Sun's Java WebStart application,
see the next section “To download the DPM Management GUI from a Web browser”. For web
browsers on Windows platforms that do not yet have Sun's Java WebStart application installed,
follow this procedure:
1. From a web browser, enter the management port (labeled MGMT) IP address as the URL and
press Enter.
HP StorageWorks SAN Virtualization Services Platform Data Path Module User Guide 69
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.

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.
Continuous Access
SVSP
An HP StorageWorks product that works with SAN storage systems to provide
asynchronous data replication (remote mirroring) between SVSP domains to
support disaster tolerance requirements. Data replication can be bidirectional,
meaning that an SVSP domain can be both a source and a destination.
crash consistent The state of the media behind a logical unit after a server crash. Pending writes
are lost.
cross-connected A property of a high-availability configuration in which both Data Path Modules
connect to a dual fabric SAN, allowing either Data Path Module to access both
controllers of a dual-controller storage array.
Data Path Module A SAN-based device, separate from the core Fibre Channel switching
infrastructure, that provides storage virtualization services across heterogeneous
hosts, storage, and SAN fabrics. The device runs a VSM fabric agent,
communicates with a VSM server, is able to process virtual disk information,
present virtual disks to servers as LUNs, and handle their I/Os by routing them
to storage systems managed by the VSM server.
default boot set The boot set that becomes the active boot set when the system is started, unless
the user selects a different boot set. Applies to the DPM.
DPM See Data Path Module.

data by carrying SCSI commands over IP networks (by encapsulating SCSI data
in TCP packets).
example, there is one kdisk per virtual disk for each unique server initiator
port–to–DPM target port combination.
to a specific sector on a back-end LU. Early PC hard drives specified the sector
in terms of its cylinder number, its head number, and its sector number. LBA
addressing uses just one number. In LBA addressing, the first sector on the
back-end LU is sector zero and all sectors on the back-end LU are simply
incremented from there. Also known as the Logical Block Number (LBN).
LUN Logical Unit Number. A unit of storage that a storage system presents to the SAN
and shows up as a back-end LU when presented to servers. Every storage system
can usually expose multiple logical units, each having a unique number (Logical
HP StorageWorks SAN Virtualization Services Platform Data Path Module User Guide 89
Unit Number), which allows servers to access that particular logical unit. LUNs
that a storage system exposes to the SVSP domain are identified by VSM as
back-end LUs.
migration A VSM service that migrates virtual disks from one storage pool to another while
the host application remains online.
mirror A VSM service that mirrors virtual disks synchronously and asynchronously.
See also asynchronous mirroring and synchronous mirroring.
mirroring The creation and continuous updating of one or more redundant copies of data,
usually for the sake of fault or disaster recovery.
OpenVMS Unit ID Abbreviated as OUID. A storage element identifier that is necessary for hosts
running OpenVMS to interact with the storage elements presented to them. This
identifier is relevant to virtual disks, snapshots, and synchronous mirror groups.
passive path A path that must have some operation (for example, a SCSI start unit command
that is issued by the server) performed on it to make it active.
See also active/active RAID, active/passive RAID, and secondary path.
patch file Incremental update to an existing system image.
persistent
reservation
A mechanism for the resolution of dynamic SCSI contention in systems with
multiple initiator ports accessing a logical unit, whereby a single initiator port
or a set of initiator ports can reserve the logical unit indefinitely. While reserved,
the storage device server rejects all commands for that logical unit from any other
initiator ports.
personality The way in which a DPM exposes LUNs to the hosts that use them. Exposing a
LUN with the correct personality (such as HP EVA VS-ALUA or HP EVA MS-DPM)
for the hosts enables features such as failover and failback between DPMs in
conjunction with the appropriate multipath software running on the host. See the
HP StorageWorks SAN Virtualization Services Platform Manager User Guide
for a list of personalities used with SVSP.
physical disk A disk device that can be discovered and managed by VSM.
PiT Point-in-Time. A VSM term denoting an entity created by a snapshot that represents
the freezing of a virtual disk’s data at a particular time and the redirection of
any further modifications to the virtual disk’s data to a new virtual disk, called a
temporary virtual disk.
POST Power-on Self Test. The diagnostic sequence executed by devices during system
startup.
primary path For an active/active or active/passive device, a path belonging to the set of
paths that are active by default, as viewed by the server.
See also active/passive RAID, active path, and secondary path.

PSCs between any two DPM initiator ports and a back-end LU presented to the
domain by an eight-port storage array (for example, an HP EVA8100).
quad A Data Path Module purpose-built ASIC that is capable of directing the data to
and from the hosts. The DPM has four quads, with all capable of communicating
across all ports, although it is desirable to keep traffic within a quad if possible.
Glossary90
Each quad contains two front or host-facing ports, and two back or storage ports.
Each of these ports is capable of a 4 Gbit/s Fibre Channel rate. Therefore, using
additional quads may be necessary as a multiple of that 8 Gbit/s or 6.4 MB/s
rate.
RPO Recovery Point Objective. The point in time to which you must recover data as
defined by your organization. This is generally a definition of what an
organization determines is an acceptable loss in a distressed situation.
RTO Recovery Time Objective. The duration of time and a service level within which
a business process must be restored after a disaster to avoid unacceptable
consequences associated with a break in business continuity.
SAN Storage Area Network. A network specifically dedicated to the task of transporting
data between storage systems and servers. SANs are traditionally connected
over FC networks but have also been built using iSCSI technology.
secondary path For an active/passive device, the set of paths that are passive by default.
See also active/passive RAID, passive path, and primary path.
setup virtual disk A virtual disk that contains the virtualized VSM configuration for the SVSP domain,
including, for example, information about storage pools and virtual disks defined
on the domain.

• A VSM service that creates multiple low-capacity, read-write snapshots of
virtual disks and makes the snapshots available to any number of hosts, for
purposes such as data recovery, backup and testing, while the original virtual
disk stays online and continues to be updated.
• A read-write entity that makes PiT data available to any host as a logical
drive.
SNMP Simple Network Management Protocol. The protocol used by the Data Path
Module to report exception conditions to third-party network management
applications.
SSH Secure Shell. A protocol and application for communicating with a remote
computer system. SSH is a more secure alternative to using telnet to communicate
with the Data Path Module.
storage pool In VSM, a set of back-end LUs or stripe sets from which you can create virtual
disks and allocate them to hosts. SVSP storage pools enable you to classify
storage elements into classes of service and provide different classes of service
to different hosts.
stripe set In VSM, a set of back-end LUs across which VSM stripes data, optionally used
to build storage pools.
