Configuration of TPDCpgCapctyTest

A common provisioning group (CPG) creates a virtual pool of logical disks that allows virtual volumes to share the CPG's resources and allocates space on demand. A CPG allows up to 65,536 virtual volumes to share a CPG's assigned resources. The allocated capacity of CPG includes usable space, snap space and administration space. This test periodically checks the usage of those spaces on the target storage system and proactively alerts administrators to potential storage space contentions so that, amends are made before application performance deteriorates.

The default parameters associated with this test are:

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

• In the HOST text box, specify the IP address of the Storage system.

• Specify the port number at which the Storage system listens in PORT textbox. The default is NULL.

• Specify the credentials of a user who has the right to execute API commands on the storage system and pull out metrics. To monitor the HP 3PAR Storage system, you will have to provide the credential of a user who has been assigned the Monitor role, in the USER and PASSWORD text boxes.

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

• The Secured Shell (SSH) port number at which the Storage system listens is specified in SSH PORT textbox. The default is 22.

• By default, this test uses the wbem.jar for metrics collection. This is why, the wbem option is selected by default. If you want the test to use the sblimCIMClient.jar for collecting metrics, choose the sblim option here.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS button will appear in this page. Clicking on this button 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.
