Enterprise Volume Manager (Multi-OS) Version 2.0D Network Administration Guide

Enterprise Volume Manager (Multi-OS) Network Administration Guide 3–3
Planning a New EVM Network
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.
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.
