Measures reported by UnityFibreTest
By periodically checking the health of the ports and measuring the I/O load on the ports, you can identify overloaded ports, isolate the storage processor they support, and thus proactively detect potential/existing load-balancing irregularities and/or processing bottlenecks with the storage processors. The UnityFibreTest test facilitates this port check. For every port configured on each of the storage processors (A and B) supported by the target storage system, this test reports the health of the ports, the I/O load on the ports and the processing ability of the ports. In the process, the test not only points administrators to overloaded ports, but also puts a finger on ports that are slow when processing I/O requests.
Outputs of the test : One set of results for each Fiber Channel Port on the target storage system being monitored.
The measures made by this test are as follows:

Note:
By default, this measure reports the Measure Values listed in the table above to indicate the current health of this Fiber Channel Port. The graph of this measure however is represented using the numeric equivalents only - 0 to 8.
