Installation Check
To verify the correct installation of the driver and to ensure that the host port is
seen by the switch, follow these steps.
To verify the correct installation of the driver:
1. Verify that the host port shows up in the switch fabric login (FLOGI)
database by issuing the one of the following commands:
show flogi database (for a Cisco FCF)
fcoe -loginshow (for a Brocade FCF)
2. If the host WWPN does not appear in the FLOGI database, provide driver
log messages for review.
Limitations
FCoE support has the following limitations:
 NPIV is not supported on ESXi by the legacy bnx2fc driver, due to
dependencies on supporting (libfc, libfcoe) components and modules. The
native qfle3f driver supports NPIV.
 Non-offload FCoE is not supported with offload-capable Marvell devices.
Only the full hardware offload path is supported.
iSCSI Support
Marvell provides the bnx2i driver to support iSCSI. The Marvell BCM57xx and
BCM57xxx iSCSI driver, bnx2i, is a Marvell VMware iSCSI Host Bus Adapter
driver. Similar to bnx2fc, bnx2i is a kernel mode driver used to provide a
translation layer between the VMware SCSI stack and the Marvell iSCSI firmware
and hardware. The bnx2i functions under the Open-iSCSI framework.
NOTE
The label Software FCoE is a VMware term used to describe initiators
that depend on the inbox FCoE libraries and utilities. Marvell’s FCoE
solution is a fully state, connection-based, hardware offload solution
designed to significantly reduce the CPU burden encumbered by a
non-offload software initiator.
The native qfle3f driver automatically starts the FCoE initialization and need
not follow these steps.
