Configuration of HpP2kCtrlrTest

This test auto-discovers the controllers of the HP P2000 SAN storage system, monitors the I/O processing ability of each controller, and reveals the following:

  • Is any controller hogging its CPU? If so, which one is it?
  • Which controller is slow in processing I/O requests? What type of requests are being serviced slowly by that controller - read requests or write requests?
  • How is the cache usage of the slow controller? Is the cache being utilized optimally, or are too many read-write requests serviced by direct disk accesses?

The answers to these questions indicate how healthy each controller is and provide pointers to right-size the processor and controller cache (if needed).

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 name of the server for which the test is to be configured has to be specified.

  • Specify the port number at which the specified HOST listens to in the PORT text box. By default, this is NULL.

  • By default, this test always connects to the HOST to collect metrics. If the HOST is unavailable, then the test will not be able to execute. This is because, the ADDITIONAL CONTROLLER IP is set to none by default. If the monitored storage device has two controllers, then you can configure the test to connect to an alternate controller, if the HOST is unreachable. For this purpose, specify the IP address of the alternate controller in the ADDITIONAL CONTROLLER IP text box.

  • By default, HP P2000 SAN storage system is not SSL-enabled. This is why, the SSL flag is set to False by default. If it is SSL-enabled, then change this flag to True.

  • In order to monitor a HP P2000 SAN storage system, the eG agent has to be configured with the credentials of a user who has been assigned the Monitor role. Specify the login credentials of such a user in the USER and PASSWORD text boxes. To know how to create such a user, click here.

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

  • The Management Controller of the HP P2000 storage system provides access for monitoring and management via the HTTP and HTTPS protocols for XML API request/response semantics. To enable the eG agent to access the management controller, invoke the XML API commands, and collect the required metrics, you need to specify the service port on the controller that listens for HTTP/HTTPS requests for XML API semantics, in the SERVICEPORT text box. By default, this is port 80.

  • Specify the time duration for which this test should wait for a response from the storage system in the TIMEOUT text box. By default, this 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 *ldquo;$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
