System Technician-Demanded T ests: Descripti ons
and Error Codes
Testing for system links is different from the standard test proced ures for
Maintenance Objects. In ad dition to testing the system link maintenance object,
the user is allowed to test all the comp onents in the path of the system link. There
are two paths preserved for the link. The c urrent path, if present, represents the
path traversed by the link c urrently. This path is not present when the link is
down. The other path, the faulted p ath, is present if the link has ever gone d own
or never come up. If the link c ame 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 whic h the link was attempted or
established unsucc essfully.
Test command for the system links, test sys-link UUCSSpp can be specified
with current or faulted as an op tional argument if the user wishes to test all the
components in the spec ified path. The tests executed will b e the same if the user
were to test each component manual ly. In the event that the user does not
specify any path, the n only the tests specified for the system links are executed.
System Link Status (#985)
This test is non-destructive. This test queries the switc h for the status of the
system link and verifies that all switc h components have the same view o f the link
state.
