Using the measures reported by the LparStatusTest, you can promptly identify guests that are powered-off and those that have been newly added/removed from the pSeries server. This page depicts the default parameters that need to be configured for the LparStatusTest.

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

• Specify the name of the pSeries server in the REAL SERVERNAME text box. If the target pSeries server has been auto-discovered using HMC, the server name will be set automatically in the REAL SERVERNAME text box. However, while configuring this test for a pSeries server that has been manually added, you have to explicitly provide the server name in the REAL SERVERNAME text box.

  Note:
  To obtain the real server name, a user can login to the target pSeries server as a valid pSeries user, go to the shell prompt of the server, and execute the following command: lssyscfg - r sys -F name

• By selecting an option from the IS MANAGED BY list, indicate whether the target pSeries server is managed using an HMC server or an IVM (Integrated Virtual Manager) server. If the target server has been auto-discovered via an HMC server, the HMC option will be automatically chosen from this list.

• This test connects to an HMC/IVM server to perform LPAR discovery and to collect host-level and “outside view” metrics from the pSeries server. To enable this communication, first, provide the IP address/host name of the HMC/IVM server in the MANAGEMENT SERVER text box. If the eG manager had automatically discovered the target pSeries server by connecting to an HMC server in the environment, then, the IP address/host name and user credentials pertaining to that HMC server will be automatically displayed in the MANAGEMENT SERVER, MANAGEMENT USER, and MANAGEMENT PASSWORD text boxes.

  However, if the pSeries server being monitored was manually added to the eG Enterprise system (and not auto-discovered via the HMC server), then, you will have to explicitly indicate whether the target pSeries server is managed by an HMC server or an IVM server by selecting an option from the IS MANAGED BY list. If the HMC option is chosen, then, you will have to provide the IP address of the HMC server that manages the target pSeries server in the MANAGEMENT SERVER text box. In such a case, in the MANAGEMENT USER and MANAGEMENT PASSWORD text boxes, you will have to provide the credentials of an HMC user who is assigned the hmcviewer role.

  On the other hand, if the IVM option is chosen from the IS MANAGED BY list, it implies that the IP address/host name and user credentials pertaining to that IVM server has to be explicitly provided in the MANAGEMENT SERVER, MANAGEMENT USER, and MANAGEMENT PASSWORD text boxes.

  Confirm the password by retyping it in the CONFIRM PASSWORD textbox.

• Set the DOMAIN parameter to none.

• The eG agent remotely communicates with each discovered LPAR on the pSeries server to obtain their "inside view". For this, the eG agent will have to be configured with the credentials of a valid user with access rights to each LPAR. If a single user is authorized to access all the LPARs on the pSeries server, provide the name and password of the user in the ADMIN USER and ADMIN PASSWORD text boxes. On the other hand, if the test needs to communicate with different LPARs using different user accounts, then, multiple user names and passwords will have to be provided. To help administrators provide these multiple user details quickly and easily, the eG administrative interface embeds a special configuration page. To access this page, simply click on the Click here hyperlink that appears just above the parameters of this test in the test configuration page. In the page that appears next, specify the following:
  • First, provide the name of the Domain to which the LPARs belong. By default, none will be displayed here.
  • The eG agent must be configured with user privileges that will allow the agent to communicate with the LPARs and extract statistics. To enable communication with one of the LPARs, specify the name of a user with access rights to that LPAR in the Admin User field.
  • The password of the specified Admin User should be mentioned in the Admin Pwd text box.
  • Confirm the password by retyping it in the Confirm Pwd text box.
  • To provide the access credentials for another LPAR, click on the circled '+' button in the page. This will allow you to add one more user specification.
  • To clear all the user specifications, simply click the Clear button.
  • To remove the details of a particular user alone, just click the circled '-' button corresponding to the user specification.
  • To save the specification, just click on the Update button. This will lead you back to the test configuration page, where you will find the multiple user names and passwords listed against the respective fields.
  • Once this is done, then, while attempting to connect to an LPAR, the eG agent will begin by using the first Admin User name of the specification. If the agent is unable to login using the first Admin User name, then it will try to login again, but this time using the second Admin User name of the specification. This routine will continue till a login attempt succeeds. Once a login attempt succeeds, then the agent will ignore the subsequent user specifications for that LPAR.

• By default, the HMC/IVM server (as the case may be) is not SSL-enabled. Accordingly, the SSL flag is set to No by default. This indicates that the eG agent will communicate with the corresponding MANAGEMENT SERVER via HTTP by default.

• Administrators of some high security LPAR environments might not have permissions to internally monitor one/more LPARs. The eG agent can be configured to ignore such 'inaccessible' LPARs using the IGNORE VMS parameter. Against this parameter, you can provide a comma-separated list of LPAR names, or LPAR name patterns, for which the inside view need not be obtained. For instance, your IGNORE VMS specification can be: *lp,aixlp*,lin*. Here, the * (asterisk) is used to denote leading and trailing spaces (as the case may be). By default, this parameter is set to none indicating that the eG agent obtains the inside view of all LPARs on a pSeries server by default.

  Note:

  While performing LPAR discovery, the eG agent will not discover the operating system of the LPARs configured in the IGNORE VMS text box.

• The DD FREQUENCY parameter refers to the frequency with which detailed diagnosis measures are to be generated for this test. For example, if this is set to 1:1, it indicates that detailed measures will be generated every time this test runs, and also every time the test detects a problem.

• Once the above value is provided, click on the Update button to register the changes made.
