About this document The EVA4100/6100/8100 uses active/active controller failover behavior instead of the active/passive controller failover behavior in VCS 3.xxx. The change to active/active will impact most host configurations. The impact of this change may involve replacing HBAs and drivers, installing new multi-pathing software, and re-establishing the correct paths to the storage system LUNs. Use this document to assess: • The impact of upgrading your EVA3000/5000 to an EVA4100/6100/8100. • Your current host configuration to determine the changes required to support active/active (if applicable). • What storage system components may have to be replaced during the upgrade. NOTE: • You must be running VCS 3.028 or later, or VCS 4.007 or later to upgrade to an EVA4100/6100/8100. • You must perform this assessment on any host connected to the storage system you are considering upgrading. Any host connected to an EVA4100/6100/8100 must be configured to support active/active I/O. • This upgrade procedure is used when upgrading to EVA4100/6100/8100 controllers. All upgraded controllers must have XCS 6.110 or later installed.
