This test reports the current state of each MDisk and the status of the RAID array that hosts the MDisks. In the process, administrators get to know which MDisks and RAID arrays are inaccessible to cluster nodes, investigate the reasons for the anomaly, and resolve it, before it affects the overall I/O performance of the storage system.

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 to which the specified HOST listens in the PORT text box.

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

• To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the DETAILED DIAGNOSIS capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

  The option to selectively enable/disable the DETAILED DIAGNOSIS capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

• 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.
