1 Installation Preparation Installing EVM host agent software involves the following major steps: 1. Reading the EVM Network Administration Guide for configuration requirements and planning. 2. Coordinating EVM Installation Activities, page 1–1 3. Verifying the Host Configuration, page 1–2 4. Verifying the EVM Server Configuration, page 1–2 5. Removing EVM V1.x Client Software, page 1–3 6. Preparing for Installation, page 2–1 7. Starting the Installation, page 2–2 8.
Installation Preparation • The EVM server is running while installing the EVM host agent. NOTE: HP recommends making sure that the EVM server is running to allow the EVM host agent installation software to establish communication with the EVM server. If necessary, the EVM host agent can be installed while the EVM server is not running. When ready, go to the next section.
Installation Preparation Make sure to have this information available during the host agent installation. To view the network name (for example, swma1A2B3C) and IP address of a Management Appliance, browse to the Management Appliance and view the HP OpenView Open SAN Manager (OSM) home page. Both items are shown in the upper right-hand corner of the page. Removing EVM V1.x Client Software If EVM V1.

4 Reinstalling the EVM Host Agent Situations may arise where a change in the EVM network requires a change to EVM server information stored by the EVM host agent. For example: • The Management Appliance is renamed or replaced. • The Management Appliance IP address changes. • The EVM server software is moved to a different Management Appliance. • A network name changes. • A host computer is reassigned for use with a different Management Appliance.
Glossary This glossary defines terms used in this guide or related to this product and is not a comprehensive glossary of computer terms. Agent In a client-server system, a program that performs information gathering or processing tasks on behalf of a client or server.

Glossary Host In StorageWorks storage systems, the controlling computer to which a storage system is attached. Job (EVM job) A file created by EVM that represents a user request to perform a task or series of tasks. For example, the EVM job named stor1_backup_daily_sales might: 1. Replicate a storage unit by the clone method to create BCV units. 2. Mount the BCV units on a server. 3. Start the tape backup of the BCV units. EVM jobs are created by using the EVM Job Add page of the GUI.
