Updating an EVM Network
If you are also adding new host computers during the update of the EVM network,
refer to Chapter 3 for host computer planning requirements on a “clean” computer.
Overview of Update Steps
1. Ensure that EVM update activities have been coordinated with users.
2. Ensure that no EVM jobs are running or “undoing” or are scheduled to run or
“undo” during the update.
3. Update the storage systems. For example, update an ACS version or add
HSV-based storage systems to the EVM network.
4. Update the Management Appliance, OSM, and HSG and HSV Element Managers
as necessary to support the storage. Do not update the EVM server yet.
5. Update Secure Path on the hosts.
6. Verify that the updated storage systems and hosts are working correctly.
7. Update the EVM server.
8. Browse to the EVM GUI. Verify that the expected storage systems appear on the
Resources page.
9. Update the EVM-enabled host computers.
10. Browse to the EVM GUI. Verify that the expected hosts and volumes appear on
the Resources page.
License Updates
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.
EVM Host Licenses
If your update adds EVM-enabled hosts, ensure that you have sufficient licenses for
the total number of hosts. If you need additional licenses, they are available in
quantities of 5, 10, or 25 hosts.
