cucsVmHbaWwnn
Module: CISCO-UNIFIED-COMPUTING-VM-MIB
OID (symbolic): CISCO-UNIFIED-COMPUTING-VM-MIB::cucsVmHbaWwnn
OID (numeric): 1.3.6.1.4.1.9.9.719.1.52.4.1.20
Node type: OBJECT-TYPE
Type: Unsigned64
Access: read-only
Description: Cisco UCS vm:Hba:wwnn managed object property
What is cucsVmHbaWwnn?
This Unsigned64 value is the World Wide Node Name (WWNN) assigned to a virtual Fibre Channel HBA (vHBA) that VM-FEX presents into a virtual machine, the Fibre Channel identity used to address this virtual HBA on the SAN. An admin needs cucsVmHbaWwnn to configure SAN-side zoning and LUN masking for this VM, since storage arrays and FC switches authorize access based on WWNN/WWPN rather than any UCS-internal ID. For example, before a VM can see its assigned LUN, the storage team must zone the array to the exact cucsVmHbaWwnn reported here for this vHBA.
