Abstract: Auto-trespass can be at least temporarily disabled subsequent to an automatic failover. The automatic failover exchanges roles between an active path and a passive path, such that the passive path becomes the active path and vice versa. By disabling auto-trespass, hosts that are unaware that the automatic failover has occurred will not trigger another failover when those hosts attempt to perform I/O operations via the formerly-active path. This can reduce performance decreases that would otherwise occur due to the active role being traded in a “ping-pong” manner between the paths.
