     1. Open the About Internet Explorer dialog.

        Note

        The steps you use to open the dialog may vary among Internet Explorer versions

     2. Check the version number. If the version number is less than 10.0.9200.17492, then you need to patch Internet Explorer with Internet Explorer update KB3087038. If the value is equal to or greater than 10.0.9200.17492, then you do not need to patch it.

     3. If you need to patch Internet Explorer, proceed to the next step. If you do not need to patch Internet Explorer, stop here.

  2. Download and install the KB3087038 patch.

• Use of identical passwords in installations

  If you reinstall or upgrade the Lenovo XClarity Integrator Add-in, use the same database/master password that you used in the previous installation.

  If you use a different password, the installation process may result in database failure, and sensitive user data that is stored in the database can become invalid.

• Rolling System Update requirements

  Before you use the Rolling System Update functions, make sure that you have met the requirements in this section.

  Make sure that you have done the following:

  • Put server hosts in clusters and ensure that the operating systems on those server hosts have already been authenticated with the OS username, OS password, and SCVMM Runas account.

  • Set Rolling System Update preferences. For detailed instructions on setting Rolling System Update preferences, see the Lenovo XClarity Integrator Add-in for Microsoft System Center Virtual Machine Manager User's Guide.

    Note

    It is especially important that the username and password for the local operating system on which the Lenovo XClarity Integrator Add-in is installed be set.
  Important

  Use the domain administrator user account for every place where user authentication information is needed, including the SCVMM Runas account.
  Note

  The Lenovo XClarity Integrator Add-in needs time to collect information from each managed server, and to fetch data and update metadata from the Lenovo website. The Rolling System Update may not work correctly for creating or editing a task during the process.

• Lenovo XClarity Integrator Add-in page display failure

  A Lenovo XClarity Integrator Add-in page occasionally fails to display or displays blank.

• The Lenovo XClarity Integrator Service session becomes invalid

  The Lenovo XClarity Integrator Add-in console logs in to the background daemon, the Lenovo XClarity Integrator Service, when the console starts. That is, a new session is created.

  The session does not expire if the console stays open and the daemon stays in service without interruption. But when the daemon is somehow interrupted, for example by being restarted, the session becomes invalid.

  When a session becomes invalid, you will observe the following symptoms:

  • The asset tree pane in the Lenovo XClarity Integrator Add-in-in shows nothing more than root nodes, or asset changes are not shown in the asset tree pane.

  • The functional UI pages display as blank or contain no data when the data should display.

  Note

  For instructions on how to check log-on history, see "Appendix B. Checking Lenovo XClarity Integrator Service sessions" in the Lenovo XClarity Integrator Add-in for Microsoft System Center Virtual Machine Manager User Guide.

  • Authenticate a hypervisor node with a Windows/domain log-on that has the WMI read permission to the target Hyper-V system.

  • Manage the server with a Lenovo XClarity Administrator, and register the Lenovo XClarity Administrator in Lenovo XClarity Integrator Add-in.

  • Discover the IMM for the specific server.

• Failed to register Lenovo XClarity Administrator with IPv6 address

  When you use an IPv6 address to register Lenovo XClarity Administrator, the message Loading, Please wait … is displayed but does not return because Lenovo XClarity Integrator Service could not get the certificate chain from the IPv6 address. This issue is a limitation of Lenovo XClarity Integrator.

  To resolve the problem, manually download the certificate from Lenovo XClarity Administrator, and add the certificate to Lenovo XClarity Integrator by clicking Manage trusted certificates > Add.
