iSCSI offload for other distributions of Linux includes the following information:
 Booting from SAN Using a Software Initiator
 Migrating from Software iSCSI Installation to Offload iSCSI
 Linux Multipath Considerations
Booting from SAN Using a Software Initiator
To boot from SAN using a software initiator with Dell OEM Solutions:
1. Access the Dell EMC System BIOS settings.
2. Configure the initiator and target entries. For more information, refer to the
Dell BIOS user guide.
3. At the beginning of the installation, pass the following boot parameter with
the DUD option:
 For RHEL 6.x, 7.x, and older:
rd.iscsi.ibft dd
No separate options are required for older distributions of RHEL.
 For SLES 11 SP4 and SLES 12 SP1/SP2:
ip=ibft dud=1
 For the FastLinQ DUD package (for example, on RHEL 7):
fastlinq-8.18.10.0-dd-rhel7u3-3.10.0_514.el7-x86_64.iso
Where the DUD parameter is dd for RHEL 7.x and dud=1 for
SLES 12.x.
4. Install the OS on the target LUN.
Migrating from Software iSCSI Installation to Offload iSCSI
Migrate from the non-offload interface to an offload interface by following the
instructions for your operating system.
 Migrating to Offload iSCSI for RHEL 6.9/6.10
 Migrating to Offload iSCSI for SLES 11 SP4
 Migrating to Offload iSCSI for SLES 12 SP1/SP2
NOTE
[[
The preceding step is required because DUDs contain qedi, which
binds to the iSCSI PF. After it is bound, Open-iSCSI infrastructure fails
due to unknown transport driver.
