Configuring Boot From SAN Using iSCSI-Based Dell Storage Arrays
e. In the Virtual Memory section, click Change.
f. In the Virtual Memory screen, select No paging file.
19. If the system will require configuration of redundant iSCSI paths to the boot image LUN, or if you
will be configuring multi-path I/O, then you will need to install additional software in the host
image for your array type:
• If you are using a Dell | EqualLogic storage array, install the Host Integration Toolkit.
3
• If you are using a PowerVault MD3000i storage array, install the Dell PowerVault MDSM
software

.
20. If you enabled the Hyper-V role, then the primary BFi LAN On Motherboard (LOM) or NIC will be
restricted automatically in Hyper-V Virtual Networks. A virtual network cannot be created on this
adapter. If a secondary BFi LOM or NIC will be configured, then you must avoid the selection of
that adapter manually when creating virtual networks.
Creating Redundant Paths to the Boot Target (Multi-
Path I/O)
After installing the operating system to the iSCSI LUN, it is recommended that you configure redundant
paths to the target from all hosts that are configured with boot from iSCSI. Misconfigured networks or
networks under heavy load may interfere with critical communication between the host and the
associated boot LUN on the target, causing the system to hang or display a blue screen.
To work around this potential problem, you can configure multiple (redundant) paths between the host
and target. As a best practice, you should configure redundant iSCSI network paths and monitor the
network performance. If you are using an MD3000i array, your redundant network paths should be on
different subnets.
NOTE: If the Hyper-V role is configured on this system, make sure that there are no virtual networks
that are bound to the physical NICs or LOMs that will be utilized for the secondary BFi adapter.
Configuring Multi-Path I/O for the Broadcom NetXtreme Adapter
For multi-path boot, you will need two network ports on the server dedicated to iSCSI SAN boot and
two iSCSI SAN IP address assignments. You should also see your iSCSI target array user documentation
for supported redundant path configurations.
1. Turn on or restart the server.
NOTE: If you are not configuring a LOM, skip to step 8.
2. Press <F2> to enter BIOS Setup during POST.
3. Select Integrated Devices and press <Enter>.
