Default Parameters for HpEvaVDiskTest

The HpEvaVDiskTest auto-discovers the LUNs on an EVA storage array, tracks the I/O requests to each LUN, and reveals how well the cache services these requests.

The parameters of 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 EVAPERFLOCATION text box, specify the full path of the directory in which the evaperf.exe has been installed.

  • Provide the name of the EVA SAN array that has been configured for monitoring in the ARRAYNAME text box.

  • The SSSULOCATION test uses the EVAPerf software component to auto-discover the LUNs on an EVA storage array. The EVA Lun Status test on the other hand uses the SSSU console to discover LUN names. During auto-discovery, the EVAPerf utility reports the WWN names of the LUNs. In contrast, the SSSU console reports the friendly names of the same LUNs.
    To ensure that these LUNs are represented using a uniform, consistent notation across the eG monitoring interface, you can optionally configure this test to use the SSSU console (instead of EVAPerf) to perform LUN discovery. This way, the names of LUNs will be the same for this test and the EVA Lun Status test. To enable LUN discovery via the SSSU console, configure the full path to the location of the SSSU.exe in the SSSULOCATION text box. If you prefer not to use SSSU.exe for LUN discovery and would rather use the EVAPerf component instead, then, set this parameter to none.

  • In the USERNAME and PASSWORD text boxes, provide the user credentials that this test will use to access the target HP EVA SAN.

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

  • In the TIMEOUT text box, indicate the duration (in seconds) for which this test should wait for a response from the storage device. By default, this is set to 60 seconds.

  • Finally, click the Update button.

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.
