1 Application Note Disabling the FCoE Function on HPE FlexFabric Adapters from QLogic Products Affected HPE Model Part Number HPE FlexFabric 10Gb 2-port 533FLR-T B21 HPE FlexFabric 10Gb 2-port 534FLR-SFP B21 HPE FlexFabric 10Gb 2-port 534FLB B21 HPE FlexFabric 10Gb 2-port 534M B21 HPE FlexFabric 10Gb 4-port 536FLR-T B21 HPE FlexFabric 10Gb 2-port 536FLB B21 HPE FlexFabric 20Gb 2-port 630FLB B21 HPE FlexFabric 20Gb 2-port 630M B21 HPE StoreFabric CN1100R HPE StoreFabric CN1100R-T QW990A N3U52A HPE Synergy 2820C B21 HPE Synergy 3820C B21 1 Introduction This application note describes a condition in VMware vsphere /ESXi environments where it is necessary to turn off or disable the Fibre Channel over Ethernet (FCoE) function on the adapters listed in the Products Affected table. 2 Issue: vmkernel Logs Filled with FCoE Data In VMware environments, when the HPE FlexFabric/StoreFabric adapter operates as NIC only, the FCoE discovery function of the Converged Network Adapter fills vmkernel logs, which overwrites the log data for other issues being investigated. To resolve this issue, the FCoE function must be disabled on the adapter when operating as NIC-only in VMware environments. SN A 1

2 3 Workaround: Disabling the FCoE Storage Function on HPE 53x/63x and CN1100 Series Adapters 3 Workaround: Disabling the FCoE Storage Function on HPE 53x/63x and CN1100 Series Adapters At the time of publication, there are three ways to disable the storage (FCoE) function on the HPE FlexFabric 53x/63x and CN1100 Series adapters. Follow the instructions for the method that best suits your system configuration. Section 3.1, Disabling FCoE in VMware Section 3.2, Removing the FCoE Driver Section 3.3, Disabling the libfcoe Driver in VMware 3.1 Disabling FCoE in VMware NOTE The following instructions disable all FCoE connectivity to the VMware host. To disable FCoE in VMware: 1. Reboot the server and launch the System Configuration menu. 2. In the System Configuration menu: a. Select the adapter. b. Ensure that the Boot to FCoE Target feature is set to Disabled. SN A 2

3 3 Workaround: Disabling the FCoE Storage Function on HPE 53x/63x and CN1100 Series Adapters 3. Issue the esxcli fcoe nic disable command to turn off the FCoE function. Instructions for using this command are located on the following VMware websites: vsphere 5 e.vcli.ref.doc_50%2fesxcli_fcoe.html 3.2 Removing the FCoE Driver vsphere 6 Remove the FCoE driver by issuing the following command in VMware: esxcfg-module -d bnx2fc 3.3 Disabling the libfcoe Driver in VMware NOTE The following instructions disable all FCoE connectivity to the VMware host. Turn off the libfcoe driver by issuing the following command: # esxcfg-module -d fcoe In addition, stop libfcoe from loading by issuing the following command: #esxcfg-module -d libfcoe_92 SN A 3

4 4 Future Workaround: Storage Personality Override Disabling the libfcoe Driver in VMware 4 Future Workaround: Storage Personality Override There will be a software update for all HPE FlexFabric 53x/63x and CN1100R Series adapters that will coincide with the release of HPE ProLiant Gen10 servers. This update will add a system configuration item called Storage Personality Override. Enabling this configuration option will disable the storage personality and eliminate the potential issue.
