Parameter testID Description Identifier for the diagnostic test to run. The identifier and corresponding tests are: 1 - Reads the test 2 - Performs a data loop-back test 3 - Writes the test discreteLines - Discrete lines diagnostic test NOTE: Discrete lines are control and status lines connected between two RAID controller modules in a RAID controller. The discrete lines test enables each RAID controller module to verify that control signal transitions can be observed at the control inputs of the alternate RAID controller module. The discrete line test automatically runs after each power cycle or RAID controller module reset. You can run the discrete lines diagnostic test after you have replaced a component that failed the initial discrete lines diagnostic test. When the test runs successfully, the following message is shown: The controller discrete lines successfully passed the diagnostic test. No failures were detected. If the test fails, the following message is shown: One or more controller discrete lines failed the diagnostic test. If the CLI cannot run the test, the CLI returns Error 270, which means the diagnostic test could not start or complete. Script Commands 143
