Testing for system links is different from the standard test procedures for MOs. In addition to testing the system link MO, the user can test every component in the path of the system link. There are two paths preserved for the link. The current path, if present, represents the path traversed by the link currently. This path is absent when the link is down. The other path, the faulted path, is present if the link has ever gone down or never come up. If the link came up and went down, then the Faulted Path is marked present. If the link never came up, the Faulted Path is marked default. In either case, it represents the path on which the link was attempted or established unsuccessfully.

Test command for the system links, test sys-link location, can be specified with current or faulted as an optional argument if the user wants to test every component in the specified path. The tests executed are the same if the user tests each component manually. In the event that the user does not specify any path, then only the tests specified for the system links are executed.
