what changes will be required to support active/active. The information you gather will be used when
upgrading the EVA 3000/5000 to VCS v4.001.

running VCS v3.028 to upgrade to VCS v4.001.
• You must perform this assessment on any host connected to the storage system you are considering
upgrading to VCS v4 .001. Any host connected to a storage system running VCS v4.001 must be
configured to support active/active I/O.
