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.

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.
Group In VSM, a virtual container that defines one or more elements for a data moving task. See also VDG. 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.
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.
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.
synchronous mirroring A mode of data mirroring in which the updates on the mirror site are synchronized between destinations. system software image A software component, capable of being updated, that contains the operating environment for the Data Path Module, including the SVSP VSM agent for the Data Path Module. target Receives commands from the initiator, and after execution, returns acknowledgement to the initiator. See also initiator.
Volume Shadow Copy Service A backup infrastructure for the Microsoft Windows Server 2003/2008 operating systems, as well as a mechanism for creating consistent point-in-time copies of data known as shadow copies. VSM Virtualization Services Manager. Short for the HP StorageWorks SAN Virtualization Services Platform Manager application. VSM API virtual disk A virtual disk that enables a host to direct VSM CLI commands to a VSM server through a DPM.
