Dell PowerVault MD3420 - Manual (Page 218)

Parameter Description
testID Specifies the identifier for the diagnostic test you
want to run. For this diagnostic test, the value is
cableDiagnostics.
Notes
When you run the cable diagnostic test, the firmware returns the following information:
• Port: The port on which the diagnostic test was run.
• The date and time the test was run.
• RAID Controller Module
• Status:
– OK: All of the pairs of cables are good and do not have any faults.
– Open: One or more of the four pairs of cables are open.
– Short: One or more of the four pairs of cables are shorted.
• Incomplete: One or more of the four pairs returned incomplete or invalid test results.
• Cable Length: The length of the cables are listed in meters and the following information about the
cables is returned:
– When the cable status is OK, the approximate lengths of the cable pairs are returned. The lengths
of the cable pairs are shown as a range (L1-L2), which are the shortest and the longest lengths of
the cable pairs.
– If the cable status is Open or Short, the approximate distance to the failure in the cable pairs. If
there is one failure, the length is reported for that cable pair. If there is more than one failure, the
information returned is both the shortest and longest lengths to the failures. The lengths are listed
as a range (L1-L2) where L1<L2.
– If the cable status is Incomplete, the information returned are the lengths for the shortest and
longest cable pairs that the firmware can successfully test. The lengths are listed for the valid cable
pairs as a range (L1-L2) where L1<L2.
• Raw Register values for the cable diagnostic registers. The values are in a hexadecimal format:
– Two bytes show the combined cable status (four bits per port).
– Four two-byte numbers show the length of each channel.
