Modify iSCSI Virtual Drive Properties in Legacy BIOS Boot Mode (BIOS)
Use this procedure to configure iSCSI virtual drives using the iSCSI BIOS
Setup Utility screens on systems configured to use Legacy BIOS Boot Mode.
iSCSI virtual drives are used primarily to run supported operating systems
that reside on an external server and that function as the local server host
operating system.
iSCSI virtual drives must be configured in the iSCSI option ROM.
Before you begin, ensure that the following requirements are met:
-
You are familiar with iSCSI theory of operation and with iSCSI server
setup procedures.
-
You have verified that iSCSI targets can be mounted on a client.
Review the operating system documentation for more information.
-
You have access to an external iSCSI server running on a supported
operating system.
-
The server is in Legacy BIOS Boot Mode, not UEFI Boot Mode. For
servers in UEFI Boot Mode, see Modify iSCSI Virtual Drive Properties in UEFI Boot Mode (BIOS).
-
Access the BIOS Setup Utility.
For instructions, see Accessing the BIOS Setup Utility.
-
Navigate to the Advanced menu, and then select Legacy iSCSI.
Note -
If you do not see Legacy iSCSI on the Advanced menu, select the IO
menu, and then select Legacy iSCSI.

-
If you deselected the Use Dynamic IP Configuration property,
specify the iSCSI initiator IP address, Subnet Mask, Gateway, and
VLAN ID.
-
Select or deselect the Use DHCP for iSCSI Target Information
property.
-
Specify the target name iSCSI Qualified Name (iqn) format, for

If you deselected the Use DCHP for iSCSI Target Information
property, specify the Target IP, Target Port, and Boot LUN.
-
Select OK.
The iSCSI Port Configuration screen reappears.
