A method and apparatus for providing host server immunization from a failover process that may occur within a data switch that couples the host server to a storage volume. To facilitate such immunization, the method and apparatus caches non-read/write information that is generated by the switch during initialization of the storage volume to host server communication. Upon failover of a switch component within a failover pair of switch components in the switch, the read/write requests issued by the server are ignored and any non-read/write information commands are responded to using the cached information.
