Updating an EVM Network
EVM Server Update
Update planning factors include the following. For specific requirements and versions,
see Chapter 5, “Configuring the EVM Network.”
• Previous EVM server - V2.0, V2.0A, V2.0B, V2.0C
• Management Appliance - no change

EVM Host Computer Updates
When you update one EVM host, you must update all EVM hosts. Before updating,
ensure that the EVM server is running V2.0D.
NOTE: HP allows you to install EVM host agent updates on computers that have not previously
been EVM enabled, provided you have sufficient EVM host licenses. When installing on a
“clean” computer, see Chapter 3, “Planning a New EVM Network” for host computer planning
requirements.
EVM Hosts Update Overview
Identify all EVM-enabled computers to be updated. On each:
1. Update the host OS version and FCA/HBA (if applicable).
2. Update the HSG or HSV Solution Software on the host (if applicable).
3. Update Secure Path on the host (if applicable).
4. Verify that the updated host is working correctly with the storage systems.
5. Update the EVM host agent.
6. Browse to the EVM GUI and verify that the expected host and volumes appear on
the Resources page.
Repeat until all hosts are updated.
The following paragraphs address EVM host agents for each supported OS. Planning
factors marked “new requirement” indicate a configuration change must be made
before updating the host agent. Factors marked “new support” indicate that a
configuration change may be required before updating.
