Viewing Inventory Information

Beginning with Cisco Prime DCNM release 6.x, you can view the inventory and the performance for both SAN and LAN switches by using the global Scope pane. You can select LAN, SAN, or both to view the inventory information. You can also export and print the inventory information.

You can either Print this information or export to Microsoft Excel.


Note
You can use the Print icon to print the information displayed or you can also use the Export icon to export the information displayed to a Microsoft Excel spreadsheet. You can also choose the column you want to display.

The Inventory menu includes the following submenus:

Viewing Inventory Information for Switches

Procedure
    Step 1   From the menu bar, choose Inventory > View > Switches.

    You see the Switches window displaying a list of all the switches for a selected Scope.

    Step 2   You can also view the following information.
    • In the Device Name column, select a switch to display the Switch Dashboard. For more information about switch dashboard, see the Switch Dashboard section.
    • IP Address column displays the IP address of the switch.
    • WWN/Chassis ID displays the World Wide Name (WWN) if available or chassis ID.
    • Health displays the health situation of the switch.
    • Satus column displays the status of the switch.
    • # Ports column displays the number of ports.
    • Model column displays the model name of the switch.
    • Serial No. column displays the serial number of the switch.
    • Release column displays the switch version.
    • License column displays the DCNM license installed on the switch.
    Step 3   In the Health column, the switch health is calculated by the capacity manager based on the following formula in the server.properties file.

    The function to implement is

    # calculate(x, x1, y, y1, z)

    # @param x: Total number of modules

    # @param x1: Total number of modules in warning

    # @param y: Total number of switch ports

    # @param y1: Total number of switch ports in warning

    # @param z: Total number of events with severity of warning or above

    Step 4   The value in the Health column is calculated based on the following default equation.

    ((x-x1)*1.0/x) *0.4 + ((y-y1)*1.0/y)*0.3 + ((z*1.0/1000>=1) ? 0: ((1000-z)*1.0/1000)*0.3).

    In the above formula, the switch health value is calculated based on the following:

    • Percentage of Warning Modules (Contributes 40% of the total health).

    • Percentage of Warning Ports (Contributes 30% of the total health)

    • Percentage of events with severity of Warning or above (Contributes 30% of the total health. If there are more than 1000 warning events, the event health value is 0).

    You may also have your own health calculation formula by implementing the common interface class: com.cisco.dcbu.sm.common.rif.HealthCalculatorRif. Add the .jar file to the DCNM server and modify the health.calculator property to point to the class name you have created.

    The default Java class is defined as: health.calculator=com.cisco.dcbu.sm.common.util.HealthCalculator.

    • Capacity Manager calculates health only for the license switches. If the health column does not display a value, the switch either does not have a license or it has missed the capacity manager’s daily cycle.

    • If the switch is unlicensed, in the DCNM License column click Unlicensed. The Administration > License window appears which allows you to assign a license to the user.

    • The capacity manager runs two hours after the DCNM server starts. So, if you discover a device after two hours of the DCNM start time, the health will be calculated 24 hours after this DCNM start time

    Viewing Inventory Information for Modules

    Procedure
      Step 1   From the menu bar, choose Inventory > View > Modules.

      You see the Modules window displaying a list of all the switches and its details for a selected Scope.

      • Group column displays the group name of the module..
      • Switch column displays the switch name on which the module is discovered.
      • Name displays the module name.
      • ModelName displays the model name.
      • SerialNum column displays the serial number.
      • 2nd SerialNum column displays the second serial number.
      • Type column displays the type of the module.
      • Slot column displays the slot number.
      • Hardware Revision column displays the hardware version of the module.
      • Software Revision column displays the software version of the module.
      • Asset ID column displays the asset id of the module.

      Viewing Inventory Information for Licenses

      Procedure
        Step 1   From the menu bar, choose Inventory > View > Licenses.

        You see the Licenses window displaying the license type and the warnings. based on the selected Scope.

        Step 2   You can view the following information.
        • Group column displays the group name of switches.
        • Switch column displays the switch name on which the feature is enabled.
        • Feature displays the installed feature.
        • Status displays the usage status of the license.
        • Type column displays the type of the license.
        • Warnings column displays the warning message.

        Discovery

        Starting from Cisco Prime DCNM release 10.x, Cisco Prime DCNM allows the admin to associate user to one or more device scope or group. That means you can only access and configure the associated group or scope devices based on Role Based Access Control (RBAC). Even though you might not have the access to other users' associated devices, you can still see all the discovered devices under the Inventory > Discovery tab.

        From the left menu bar, go to Administration > Management Users. You can create users and associate groups, mange remote authentication and see all the connected clients. For more information about RBAC, please go to Management Users.
