This test monitors the I/O operations on each MDisk in each node of the storage system, reports how well every MDisk processes the I/O, and reveals processing latencies (if any) in that MDisk. This way, MDisks that are overloaded, those that are slow in processing I/O, and the nodes that such MDisks are mapped to, can be accurately identified.

This page depicts the default parameters that need to be configured for the IBMV7000MDiskTest.

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

• Specify the duration (in seconds) beyond which the test will timeout in the TIMEOUT text box. The default value is 30 seconds.

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

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz” and $port will be changed to “80” when configuring a test.
