Default Parameters for UnityDiskTest

This test monitors the load balancing capability of each disk of the target storage system. Using this test, administrators can pin point the disks that are handling more I/O requests than the rest. This way, irregularities in the distribution of I/O load across disks can be detected at ease and in the process, administrators would be able to fine-tune the load-balancing algorithm. In addition, the test also proactively alerts administrators to probable slowdowns in I/O processing by specific disks, thereby enabling administrators to initiate pre-emptive actions.

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

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

• The eG agent uses the command-line utility, UEMCli.exe, which is part of the UniSphere Management Suite, to communicate with and monitor the storage device. To enable the eG agent to invoke the CLI, configure the full path to the CLI in the UNISPHERE CLI PATH text box.

• Provide the credentials of a user possessing monitor role to access the storage device in the USERNAME and PASSWORD text boxes.

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

• Specify the duration (in seconds) beyond which this test should time out in the TIMEOUT text box. The default is 300 seconds.

• Once the above values are provided, click on the UPDATE button to 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.
