Enterprise Volume Manager (Multi-OS) Network Administration Guide 1–5

This chapter presents a basic introduction to the Enterprise Volume Manager, discussing its purpose, its components, and its basic configuration.

What Is EVM?

EVM is an application program that makes point-in-time copies of storage volumes. These copies, called Business Continuance Volumes (BCVs), can be mounted dynamically on any other supported host in the EVM storage network. To replicate storage volumes, EVM requires the establishment of an EVM network. Figure 2–1 shows a typical EVM network.

The EVM network consists of the following hardware and software components.

• One HP OpenView Management Appliance

• One or more host computers

• One or more HP StorageWorks storage systems

Enterprise Volume Manager (Multi-OS) Network Administration Guide 2–1

Introduction to EVM

• EVM server software, which runs on the management appliance

• EVM host agent software runs on the user’s host computer systems that are part of

the EVM network.

• Storage Element Manager, which runs on the management appliance

The EVM server manages the EVM network, manages EVM jobs, and provides the Web browser interface to users. The EVM server is installed on an HP OpenView Management Appliance. Another EVM component, called the EVM host agent, is installed on host computers and participates in the EVM jobs created for volume management. StorageWorks storage systems provide the storage that is used in EVM jobs.

An EVM network is often a subset of an existing Fibre Channel storage area network (SAN). The SAN consists of host computers, StorageWorks storage systems, and switches that are connected by fiber optic cabling. The Fibre Channel carries storage data transmitted between StorageWorks storage systems and host computers.

The computers in an EVM network are also connected by a Local Area Network (LAN) and communicate with each other by a TCP/IP connection. The LAN carries command and status data transmitted between network components.

The EVM network and its associated StorageWorks storage systems can be managed remotely using a Web browser. From the Web browser the user logs in to the management appliance and the EVM server and then has access to the EVM graphical user interface (GUI).

What the Management Appliance Does

EVM server software runs on the HP OpenView Management Appliance. The Management Appliance provides a centralized facility for managing and monitoring SAN elements, including storage arrays. Management Appliance software includes element managers for both HSG-based and HSV-based storage systems. The element managers allow users to manage storage through GUI interfaces, which are accessed through a Web browser.

IMPORTANT: To use EVM with HSV-based storage systems, you must separately enter (on the EVM Configuration page) the same user name and password that you entered in the OSM (Open SAN Manager) Account Login page. See the online Help/User Guide for HSV password details.

EVM networks are accessible from systems that have an Internet Explorer or Netscape Web browser (see Table 5–12 on page 5–13 for browser compatibility with host operating systems).

What the EVM Server Does

The EVM server software controls all activities within the EVM network. The EVM server software provides:

• An engine for running EVM storage replication jobs.

• EVM job creation and job management functions. These features allow the

creation, validation, and management of jobs. All EVM jobs are stored on the Management Appliance.

• EVM Resources, Jobs, Logs, and Configuration pages. These displays provide

information that helps to identify available resources, create and manage jobs, log EVM activities, and manage storage system visibility.

• An HTTP server for EVM. The HTTP server allows the use of a Web browser to

access all of the features of EVM.

What an EVM Host Agent Does

The EVM host agent software is installed on a host computer and performs all activities associated with running EVM jobs within the EVM network, as directed by the EVM server.

The host agent software provides an EVM Command Line and job engine. These two elements provide the means for running EVM jobs. The host agent software also provides communication between the host computer and the EVM server.

Introduction to EVM

Enterprise Volume Manager (Multi-OS) Network Administration Guide 2–3

Planning a New EVM Network

This chapter provides information on planning a new EVM network. Before installing EVM software, HP recommends reading this planning chapter and Chapter 5, “Configuring the EVM Network,” and completing the EVM network planning worksheets in Appendix A.

This chapter discusses the following topics, which are the basic steps in planning an EVM network:

• Determining the Purpose of the EVM Network on page 3–1

• Licenses on page 3–1

• Storage Systems Planning on page 3–2

• EVM Server Planning on page 3–3

• EVM Host Computer Planning on page 3–4

• Sample Worksheets on page 3–5

Determining the Purpose of the EVM Network

The first step in planning an EVM network is to specify its purpose. Determine, for example, whether the network is intended for centralized backup, data warehousing, or application testing.

After specifying the purpose of the EVM network, consider the EVM-SAN configuration that best supports the operational requirements for that network. See Chapter 5, “Configuring the EVM Network,” for sample configurations.

Licenses

In addition to the license that is required for the EVM server, other licenses are required to view EVM network resources and include them in EVM jobs.

Enterprise Volume Manager (Multi-OS) Network Administration Guide 3–1

Planning a New EVM Network

EVM Host Licenses

The EVM kit contains one EVM server license and a license for five EVM hosts. If your planned EVM network includes more than five EVM-enabled hosts, you will need to purchase a license for additional hosts. Host licenses are available in quantities of 5, 10, or 25 hosts.

VCS Snapshot Licenses

If your planned EVM network includes HSV-based storage systems, you must have a VCS snapshot license for each. EVM cannot access an HSV-based storage system unless the storage system has a VCS snapshot license.

Storage Systems Planning

An EVM network must include at least one storage system and can include many storage systems. However, for the best overall performance, an EVM network should include only storage systems that you intend to include in EVM jobs.

If your SAN configuration (and planned EVM network) must include storage systems that you do not intend to use with EVM, you can browse to the EVM Configuration page and deselect them. This improves EVM performance but does not limit their use outside of EVM.

Before installing EVM, ensure the following are addressed. For specific requirements and versions, see Chapter 5, “Configuring the EVM Network.”

HSG-based Storage Systems

• You have identified the HSG-based storage systems that you want to use in the EVM network, if any.

• The number of storage systems does not exceed the number that the Management Appliance supports.

• Each HSG-based storage system is controlled by an element manager (and not by a StorageWorks Command Console agent).

• Each HSG-based storage system has an EVM supported ACS and is configured for multibus failover.

3–2 Enterprise Volume Manager (Multi-OS) Network Administration Guide

HSV-based Storage Systems

• You have identified the HSV-based storage systems that you want to use in the

EVM network, if any.

• The number of storage systems does not exceed the number that the Management

Appliance supports.

• Each HSV-based storage system has an EVM supported VCS with snapshot

license.

EVM Server Planning

An EVM network must include one, and only one, EVM server running on a Management Appliance. In addition, EVM can access only those storage systems that are controlled by element managers that are on the same appliance as the EVM server software.

If your SAN configuration (and planned EVM network) includes more than one Management Appliance, you need to select the one on which to install the EVM server software. Any other Management Appliances should be excluded from (zoned out of) the EVM network.

Planning a New EVM Network

Before installing the EVM server software, ensure the following are addressed. For specific requirements and versions, see Chapter 5, “Configuring the EVM Network.”

Management Appliance and OSM

• You have identified the Management Appliance that you want to use with EVM.

• Storage that you want to use with the EVM is controlled by that Management

Appliance.

• The Management Appliance is on the same LAN as the planned EVM host

computers.

• The Management Appliance is running an EVM supported version of OSM.

HSG and HSV Element Managers

• For HSG-based storage systems, the Management Appliance is running an EVM

supported version of the HSG Element Manager.

• For HSV-based storage systems, the Management Appliance is running an EVM

supported version of the HSV Element Manager.

Planning a New EVM Network

EVM Host Computer Planning

An EVM network can include many EVM-enabled host computers. For a computer to be EVM-enabled, you must install EVM host agent software on it.

In terms of EVM job operations, you need a computer to be EVM enabled to:

• Replicate storage volumes by specifying the host name.

• Suspend or resume host I/O (in conjunction with replication).

• Mount volumes on the host.

• Launch (start) an external job or issue a host command.

Selecting which computers are to be EVM enabled is largely a matter of reviewing your operational needs. Typically, EVM host computers are database servers and tape backup servers, although there is no EVM limitation on how a host is used.

Before installing EVM host agent software, ensure the following are addressed. For specific requirements and versions, see Chapter 5, “Configuring the EVM Network.”

Host Operating System, FCA/HBA and LAN

• Each host is running an EVM supported operating system.

• Each host is connected to storage systems via EVM supported FCA/HBAs.

• Each host is on the same LAN as the Management Appliance (EVM server).

HSG or HSV Solution Software

• Each host is running EVM supported drivers from an HSG Solution Software kit.

• Or, the host is running EVM supported drivers from an HSV Operating System

kit.

Secure Path

• Each host is running an EVM supported version of StorageWorks Secure Path.

• Or, the host has EVM supported multipath support in the OS (for example, HP

Tru64 UNIX).
