7.1.2 Accessing iManager

  1. Launch a Web browser.

  2. Click File > Open, then enter

    https://server-IP-address/nps/iManager.html
    

    The URL is case sensitive. Replace server-IP-address with the actual server DNS name or IP address. For example:

    
    https://192.168.1.1/nps/iManager.html
    

    The iManager Login page opens.

  3. Use your administrator username and password to log in to the Novell eDirectory™ tree that contains the server you want to manage.

    In Novell iManager, you can access only the roles and tasks you are authorized to manage. For full access to all available Novell iManager features, you must log in as Supervisor of the tree.

7.1.3 Accessing Roles and Tasks in iManager

  1. Access iManager, then log in to the eDirectory tree where the server you want to manage resides.

    For information, see Section 7.1.2, Accessing iManager.

  2. In Roles and Tasks, do one of the following:

    • Expand the Distributed File Services role to reveal its main tasks.

    • Expand the Storage role to reveal its main tasks. The DFS Move Volume and Split Volume tasks are located on the Volumes page.

      The iManager NSS Storage Management Role and Tasks

    As you work in the storage-related plug-ins, use the navigation links at the top of the page, referred to as “breadcrumbs,” to return to pages you recently visited, or use the links in Roles and Tasks. If you use the Refresh and Back features of your Web browser to navigate, iManager returns you to the initial page you encountered after login.

  3. To activate the options on the selected page, select a server to manage.

    For information, see Section 7.1.4, Selecting a Server to Manage.

7.1.4 Selecting a Server to Manage

Before you can access the management options on a selected task page, you must select a server to manage that is in the same Novell eDirectory tree where you are currently logged in.

  1. Use one of the following methods to select a server in the tree where you are logged in:

    Server Search Field
    • Type the Novell eDirectory distinguished server name for the server you want to manage, then press Tab or click somewhere on the page outside of the Server field to enter your selection. For example: svr1.company.

    • Click the Search icon to open the eDirectory Object Selector. Browse or search the list to locate the server you want to manage, then click the server name.

    • Click the Object History icon to select a server you have recently managed.

  2. Wait for iManager to retrieve information about that server and display the appropriate information to the task page you are in.

    It might take several seconds to retrieve the information, depending on the size and complexity of your storage solution.

7.1.5 Distributed File Services Plug-In

The Distributed File Services plug-in for Novell iManager 2.7 provides the tasks described in this section.

Volume Job Control

After you use the Move Volume or Split Volume tasks on the Storage > Volumes page, use Distributed File Services > Volume Job Control to manage those jobs. For information about the Move Volume and Split Volume tasks, see Section 7.1.6, Storage Plug-In.

7.1.7 Files and Folders Plug-In

You can optionally use the Files and Folders > Properties > Rights page to view and modify trustees, trustee rights, and the inherited rights filter on either the junction or the target location. There is no ability to copy between the two locations as there is in the Distributed File Services > Modify Junction page. For a quick reference for the Files and Folders plug-in, see Files and Folders Plug-In Quick Reference in the NW 6.5 SP8: NSS File System Administration Guide.

7.1.8 WBEM

You must make sure CIMOM is running on the server you want to manage if the task you are performing changes values in eDirectory. If CIMOM is not running, the plug-in does not perform the task.

For DFS for Linux, this affects the following tasks:

  • Creating or deleting an DFS Management context

  • Adding or removing a Replica server

WBEM is loaded and runs automatically when you start the server.

IMPORTANT:If you receive file protocol errors, it might be because WBEM is not running.

To check the status of WBEM:

  1. As root in a console shell, enter

    rcowcimomd status
    

To start WBEM:

  1. As root in a console shell, enter

    rcowcimomd start
    

For information about installing WBEM, see Setting Up OpenWBEM in the NW 6.5 SP8: OpenWBEM Services Administration Guide.
