Start Diagnostics Test
Diagnostic tests interrupt normal HBA operations. At the completion of the testing,
the HBA’s state before the tests are restored. Note the following:
Run these tests when no other activities are required of the HBA.
Tests read and write to sensitive areas on the HBA.
Disruption of some diagnostic tests may require a complete update of the
HBA's critical memory areas.
NOTE:
Although SANsurfer FC CLI protects against normal operation interruption
and testing disruption, it is your responsibility to ensure that the diagnostics
are run without causing interruptions to other processes and disruptions to
the actual testing process.
