Management. Click on Device Manager. You should see two unknown Ethernet Controllers
and two Network Controllers under Other devices, as shown in Figure 16-2.
Figure 16-2 Device Manager
Properties (right-click) for each of those four unknown devices shows that they all belong to
the same device, representing different functions. In this configuration it is
PCI Slot 6 on PCI Bus 13, device 1 and function 0 for the first Ethernet Controller
PCI Slot 6 on PCI Bus 13, device 1 and function 2 for the second Ethernet Controller
PCI Slot 6 on PCI Bus 13, device 1 and function 1 for the first Network Controller
PCI Slot 6 on PCI Bus 13, device 1 and function 3 for the second Network Controller
The QLogic iSCSI Expansion Card for BladeCenter is a dual port adapter. Each port has two
different functions that are visible here as Ethernet Controller and Network Controller. Port 0
has function 0 and 1 and port 1 has function 2 and 3. The Ethernet Controller Function is a
regular Ethernet interface that can be used just like any other Ethernet NIC. This interface
does not benefit from the offload capabilities of this adapter.
The Network Controller function that each of the ports owns is an iSCSI port.
The Ethernet controller requires an NDIS driver and the Network Controller requires an iSCSI
driver. These driver packages can be downloaded from
http://support.qlogic.com/support/oem_detail_all.asp?oemid=369
.
At this Web site, partially shown in Figure 16-3 on page 345, you will find packages
containing the iSCSI driver but no NDIS driver, (Storage only) and packages that contain both
drivers. In our configuration, we use the driver package without the NDIS driver because we
do not need the NDIS function to connect to a DS3300.
Note: When both function of a port are used, different IP addresses must be assigned.
