Enterprise Volume Manager (Multi-OS) Network Administration Guide 4–3
Updating an EVM Network
VCS Snapshot Licenses
If your update adds HSV-based storage systems, you must have a VCS snapshot
license for each. EVM cannot access an HSV-based storage system unless the storage
system has a VCS snapshot license.
Storage Systems Updates
When you update an EVM network, you may also need to update some aspects of the
storage systems.
Storage Systems Update Overview
Identify the storage systems that require updating to interact with EVM.
1. Update the ACS on HSG-based storage systems (if applicable).
2. Reconfigure the failover mode to multibus on HSG-based storage systems (if
applicable).
3. Update the VCS on HSV-based storage systems (if applicable)
4. Verify that the Management Appliance is working correctly with the storage
systems.
In the following paragraphs, planning factors marked “new requirement” indicate a
configuration change must be made to work with EVM server V2.0D. Factors marked
“new support” indicate that a configuration change may be required.
