7–Configuring FCoE in a Windows Environment
Boot from SAN
7-16 FE0254601-00 A
If failover capabilities are required during boot-from-SAN, multiple QLogic
8100 Series Adapters are required to create redundant paths to the boot
device. Consult the server manufacturer’s documentation to determine the
maximum number of QLogic 8100 Series Adapters that the server can
support.
Converged Network Adapter Requirements
The Converged Network Adapter must meet the following requirements:
QLogic 8100 Series Adapter with current firmware.
QLogic 8100 Series Adapter with the boot BIOS is enabled. Typically, the
boot BIOS is disabled by default. Disregard this requirement if a
UEFI-enabled server is used.
If failover capabilities are required during boot-from-SAN, multiple QLogic
8100 Series Adapters are required to create redundant paths to the boot
device.
Record the WWPN and WWNN for each adapter prior to installation. The
WWPN and WWNN can be found on a label on the adapter.
FCoE Switch Requirements
Ensure that the FCoE switch has the correct zoning configuration according to the
following rules:
Locate the FCoE switch on the SAN that contains the boot LUN so that the
FCoE switch is visible to the server through the QLogic adapter.
The host must have exclusive access to the LUN from which it boots. No
other host on the SAN should be able to detect or access the same logical
disk.
Only one instance of the boot LUN can be visible to the server during the
initial installation. The installation may fail if multiple instances of the boot
LUN are available to the server through different paths or through the same
LUN presented through two different storage array controllers. If failover is
required, configure boot-from-SAN after the initial installation is complete.
Limit zones to no more than one adapter port to avoid RSCN interruptions
from other hosts in the fabric.
Storage Array Requirements
Some storage arrays cannot support boot-from-SAN for specific environments.
Consult the storage array manufacturer’s documentation to confirm that the array
and the firmware support boot-from-SAN. Consider the storage array and any
limitations regarding boot-from-SAN.
Create and present an appropriately sized LUN to the QLogic 8100 Series
Adapter port.
