This section contains context-sensitive Online Help content for the Web Client > Inventory tab.
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:
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.
|
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:
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.

The HBA Link Diagnostics feature helps in validating the health of links between Host Bus Adapters (HBAs) and Cisco MDS switches in a network. The servers connect to Storage Area Networks (SANs) through hardware devices are called HBAs. This connectivity comprises of many optical and electrical components that may develop faults during their lifetime. The HBA Link Diagnostics feature allows identification of faulty cables, transceivers, ASICs, drivers, firmware issues or software issues, thereby eliminating dropped frames and ensuring reliable I/O operations of the server.
For more information about the Configuring HBA Link Diagnostics for Cisco MDS switches in a network, see the Cisco MDS 9000 Series NX-OS System Management Configuration Guide.
From the menu bar of Cisco DCNM Web Client, choose Interfaces tab. The HBA diagnostic button appears in the interfaces tab for SAN discovered switches. Click the HBA diagnostic button to launch Host Diagnostic. The Link Diagnostic screen appears.
, and then click theCisco DCNM 10.4(1) enables you to run HBA Link Diagnostics on the following platforms:

The Fabric Extender feature allows you to manage a Cisco Nexus 2000 Series Fabric Extender and its association with the Cisco NX-OS switch that it is attached to. A Fabric Extender is connected to the switch through physical Ethernet interfaces or a Port Channel. By default, the switch does not allow the attached Fabric Extender to connect until it has been assigned a chassis ID and is associated with the connected interface. You can configure a Fabric Extender host interface port as a routed or Layer 3 port. However, no routing protocols can be tied to this routed interface.
Note | FEX feature is available on LAN devices only. Therefore, you will see FEX on Cisco DCNM Web Client > Inventory Switches. If a Cisco Nexus Switch is discovered as part of SAN fabric, FEX feature is not available. FEX is also not supported on Cisco Nexus 1000V devices. |
Note | 4x10G breakout for FEX connectivity is not supported on Cisco Nexus 9500 Switches. |
Note | The Fabric Extender may connect to the switch through a number of separate physical Ethernet interfaces or at most one port channel interface. |

If the FEX is physically connected to the switch, FEX will become online after it is added. If the FEX is not physically connected to the switch, the configuration will be deployed to the switch, which in turn will enable FEX when connected.
Note | You can create only single homed FEX through Cisco DCNM Web Client > Inventory > Switches > FEX > Add FEX. To create a dual-homed FEX, use the vPC wizard through Cisco DCNM Web Client > Configure > Deploy > vPC. For more information, see Add vPC. |
Ensure that you have successfully discovered LAN devices and configured LAN credentials before you configure FEX.
To edit and deploy FEX, perform the steps below.
Step 1 | From the menu bar, select Inventory > Switches > FEX. | ||

This section describes how to manage virtual device contexts (VDCs) on Cisco Nexus 7000 Switches through Cisco DCNM.
Users with the network administrator (network-admin) role can create virtual device contexts (VDCs). VDC resource templates limit the amount of physical device resources available to the VDC. The Cisco NX-OS software provides a default resource template, or you can create resource templates.
You can create and manage VDCs from Cisco DCNM Web Client > Inventory > Switches > VDCs. As Cisco DCNM supports DCNM on Cisco Nexus 7000 Series only, click on an active Cisco Nexus 7000 Switch. After you create a VDC, you can change the interface allocation, VDC resource limits, and the high availability (HA) policies.
