Is SANworks Secure Path Required?
No. It is not a requirement that Secure Path be installed to use EVM.
Planning Use of EVM with SANworks Secure Path
EVM mounts BCVs on a single path. This means that BCV units created by EVM are not path fault-tolerant when used with the controller's multibus mode and Secure Path.
Secure Path normally deals with units that are visible to a host on two separate paths and its interface will report that BCVs created by EVM only have one available path.
In transparent failover mode, BCVs created by EVM are not affected by this limitation.
About SANworks Secure Path
SANworks Secure Path is host-based, multipath software that provides automatic error recovery from server-to-storage subsystem connection failures.
Secure Path supports redundant Fibre Channel paths between hosts and a storage subsystem. If any component in the path between the host and storage subsystem fails, Secure Path immediately redirects all pending and subsequent I/O requests from the failed path to an alternate path.
