• License Updates on page 4–2

• Storage Systems Updates on page 4–3

Determining the Purpose of the Update

The first step in planning an update of the EVM network is to specify its purpose. For

example:

• Update the EVM server and host agents only for feature enhancements and bug

fixes.

• Add new OS support.

• Add HSV-based storage systems.

• Maintain interoperability with other StorageWorks products.

In all cases, you will need to update the EVM server and all EVM host agents in the

EVM network. In some cases, you may need to change or update storage and host

configurations before you update the EVM server or EVM host agents.
