15.3 Managing FCoE Services with YaST

You can use the YaST FCoE Client Configuration option to create, configure, and remove FCoE interfaces for the FCoE disks in your Fibre Channel storage infrastructure. To use this option, the FCoE Initiator service (the fcoemon daemon) and the Link Layer Discovery Protocol agent daemon (llpad) must be installed and running, and the FCoE connections must be enabled at the FCoE-capable switch.

  1. Launch YaST and select Network Services > FCoE Client Configuration.

  2. On the Services tab, view or modify the FCoE service and Lldpad (Link Layer Discovery Protocol agent daemon) service start time as necessary.

    • FCoE Service Start: Specifies whether to start the Fibre Channel over Ethernet service fcoemon daemon at the server boot time or manually. The daemon controls the FCoE interfaces and establishes a connection with the llpad daemon. The values are When Booting (default) or Manually.

    • Lldpad Service Start: Specifies whether to start the Link Layer Discovery Protocol agent llpad daemon at the server boot time or manually. The llpad daemon informs the fcoemon daemon about the Data Center Bridging features and the configuration of the FCoE interfaces. The values are When Booting (default) or Manually.

    If you modify a setting, click OK to save and apply the change.

  3. On the Interfaces tab, view information about all of the detected network adapters on the server, including information about VLAN and FCoE configuration. You can also create an FCoE VLAN interface, change settings for an existing FCoE interface, or remove an FCoE interface.

    Use the FCoE VLAN Interface column to determine whether FCoE is available or not:

    Interface Name

    If a name is assigned to the interface, such as eth4.200, FCoE is available on the switch, and the FCoE interface is activated for the adapter.

    Not Configured:

    If the status is not configured, FCoE is enabled on the switch, but an FCoE interface has not been activated for the adapter. Select the adapter, then click Create FCoE VLAN Interface to activate the interface on the adapter.

    Not Available:

    If the status is not available, FCoE is not possible for the adapter because FCoE has not been enabled for that connection on the switch.

  4. To set up an FCoE-enabled adapter that has not yet been configured, select it and click Create FCoE VLAN Interface. Confirm the query with Yes.

    The adapter is now listed with an interface name in the FCoE VLAN Interface column.

  5. To change the settings for an adapter that is already configured, select it from the list, then click Change Settings.

    The following options can be configured:

    FCoE Enable

    Enable or disable the creation of FCoE instances for the adapter.

    DCB Required

    Specifies whether Data Center Bridging is required for the adapter (usually this is the case).

    Auto VLAN

    Specifies whether the fcoemon daemon creates the VLAN interfaces automatically.

    If you modify a setting, click Next to save and apply the change. The settings are written to the /etc/fcoe/cfg-ethX file. The fcoemon daemon reads the configuration files for each FCoE interface when it is initialized.

  6. To remove an interface that is already configured, select it from the list. Click Remove Interface and Continue to confirm. The FCoE Interface value changes to not configured.

  7. On the Configuration tab, view or modify the general settings for the FCoE system service. You can enable or disable debugging messages from the FCoE service script and the fcoemon daemon and specify whether messages are sent to the system log.

  8. Click OK to save and apply changes.
