Software FCoE LUNs (deprecated)

October 14, 2025

Contributed by:

Software FCoE provides a standard framework to which hardware vendors can plug in their FCoE-capable NIC and get the same benefits of a hardware-based FCoE. This feature eliminates the need for using expensive HBAs.

Note:

Software FCoE is deprecated and will be removed in a future release.

Before you create a software FCoE storage, manually complete the configuration required to expose a LUN to the host. This configuration includes configuring the FCoE fabric and allocating LUNs to your SAN’s public worldwide name (PWWN). After you complete this configuration, the available LUN is mounted to the host’s CNA as a SCSI device. The SCSI device can then be used to access the LUN as if it were a locally attached SCSI device. For information about configuring the physical switch and the array to support FCoE, see the documentation provided by the vendor.

Note:

Software FCoE can be used with Open vSwitch and Linux bridge (deprecated) as the network back-end.

Device-config parameters for FCoE SRs are:

Parameter Name	Description	Required?
`SCSIid`	The SCSI bus ID of the destination LUN	Yes

Create a Software FCoE SR

Before creating a Software FCoE SR, customers must ensure that there are FCoE-capable NICs attached to the host.

xe CLI

Run the following command to create a shared FCoE SR:

    xe sr-create type=lvmofcoe \
    name-label="FCoE SR" shared=true device-config:SCSIid=SCSI_id
<!--NeedCopy-->

In XenCenter®

To open the New Storage Repository wizard, do one of the following actions:
- On the toolbar, click New Storage.
- On the Storage tab for the selected pool or server, click New SR.
- On the Storage menu, click New SR.
- In the Resources pane, select a server or pool then right-click and click New SR on the shortcut menu.
Select Software FCoE as the Storage type and click Next.
Enter a name for the new SR. By default, the wizard generates a description of the SR. This description includes a summary of the configuration options you select as you progress through the wizard. To enter your own description, clear the Auto-generate description check box and type in the Description box. Click Next to continue to the Location page.
XenCenter® probes for available LUNs and displays a list of LUNs currently exposed to the host. This page also displays detailed information about the LUN such as, the size, serial, ID, NIC. Choose the LUN (s) that you want to allocate to the SR and click Next.

Note:

If the host cannot find any LUNs, an error message is displayed. Verify your hardware configuration and retry to continue with the SR creation process.
Review the summary and click Finish to complete the SR creation process.
