Default Parameters for HpEvaDiskTest

The HpEvaDiskTest monitors the level of I/O activity on each physical disk on an EVA storage array, and helps isolate irregularities in load balancing across the disks.

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 physical disks on an EVA storage array. The EVA Physical Disk Status test on the other hand uses the SSSU console to discover physical disk names. During auto-discovery, the EVAPerf utility reports the WWN names of the physical disks. In contrast, the SSSU console reports the friendly names of the same physical disks.
  To ensure that these physical disks 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 physical disk discovery. This way, the names of physical disks will be the same for this test and the EVA Physical Disk Status test. To enable physical disk 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 physical disk 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.
