HP StorageWorks EVA Cluster Extension Software Installation Guide (T3667-96044, April 2010)

General installation prerequisites
This section describes general installation prerequisites for EVA Cluster Extension.
Environmental setup
Ensure that the following conditions are met before installing EVA Cluster Extension Software:
• Continuous Access EVA links (including extender hardware) are redundant and bidirectional.
• Alternate I/O paths between servers and the EVA storage system are set up.
• Cluster and client networks are redundant.
• Cluster nodes can communicate with each other (not required for Windows Server 2003).
• The latest supported software and firmware versions, fixes, FC adapter firmware, and driver versions
for your servers and EVA storage systems are installed.
• The cluster nodes in your zoning configuration each recognize their respective (local) EVA, but
not the remote EVA. Each management server recognizes both EVAs and can recognize each
other. Figure 1 on page 9 shows a zoning example.
