Configuration of LHVolumePerfTest

This test auto-discovers the volumes in each storage cluster of the target storage system and reports how well each volume handles the I/O requests it receives. In addition, this test reveals the time taken to complete read and write operations on each volume. This way, the test turns the spotlight on volumes that are experiencing a slowdown and also reveals what is causing the slowdown - load-balancing irregularities across volumes or poor I/O processing capability?

The default parameters associated with this test are as follows:

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

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

• In the PORT text box, specify the port at which the target host is listening.

• The eG agent uses the command-line interface, CLIQ.exe, to communicate with and monitor the storage cluster. To enable the eG agent to invoke the CLI, configure the full path to the CLI in the CLI PATH text box.

• Specify the credentials of a user who can execute the CLIQ.exe on the host that is connected with the storage cluster in the USERNAME and PASSWORD text boxes.

• Confirm the password by retyping it in the CONFIRM PASSWORD text box.

• 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 servers, 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.
