Using this test, you could analyze the following:

• How well the data is transmitted to/received from the hosts and controllers through each port of the nodes of the IBM Storwize v7000 storage device.
• How well the commands are initiated to the controllers through each port thus helping you to identify the port that is overloaded.
• The number of link failures, synchronization failures of each FC port
• the number of times signal was lost in each FC port
• Errors such as Primitive Sequence portocol errors, invalid word transmission, invalid CRCs transmitted through each FC port and
• The time duration for which each FC port was unable to send the frames due to lack of buffer credit

The default parameters associated with this test are as follow:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• In the HOST text box, specify the host for which the test is to be configured.

• Specify the port number at which the specified HOST listens in the PORT text box. By default, this is NULL.

• Specify the duration (in seconds) beyond which the test will timeout in the TIMEOUT text box. The default value is 60 seconds.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the Update button will register the changes made.

When changing the configuration for specific components, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
