HP StorageWorks Business Copy EVA V3.x Administrator Guide (T3680-96001, April 2005)

12 Planning and best practices
Planning local replication upgrades
Replication components have many dependencies and relationships to other SAN components. For
supported versions of related products, see HP StorageWorks EVA software compatibility reference on the
HP StorageWorks Business Copy EVA web site. When planning upgrades, consider the following:
Interface versions
Before upgrading a local replication interface, ensure that the interface prerequisites are met. There may
be compatibility requirements for management servers, hosts, and browsing computers.
Hosts
If replication host agents are installed, ensure that the update is compatible with the host agent and other
applications on the host. Some typical issues include:
• Operating system type and version
• File system types
• Logical volume manager type and version
• Cluster software type and version
• Fibre Channel HBA type and driver version
• Multipath software type and version
Browsing computers
When updating browsing computers, ensure compatibility with HP Command View EVA and other local
replication software. Some typical compatibility issues include:
• Operating system type and version
• Browser type and version
• JRE type and version
SANs with MA/EMA arrays
If you are using HP StorageWorks Business Copy EVA/MA/EMA for local replication on EVA and
MA/EMA arrays, consider MA/EMA compatibility when upgrading.
