System Technician-Demanded Tests:
Descriptions and Error Codes
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 wishes 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.
