Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Due to the inability of multipathd (a path monitoring daemon) to distinguish between deleted and recently added but not yet fully initialized devices, it used to take more than a minute to remove a dead path and reload the device with a new one. This has been fixed and multipathd now removes the deleted devices immediately.
