iSCSI Boot
Marvell BCM57xx and BCM57xxx gigabit Ethernet (GbE) adapters support iSCSI
boot to enable network boot of operating systems to diskless systems. iSCSI boot
allows a Windows, Linux, or VMware operating system boot from an iSCSI target
machine located remotely over a standard IP network.
For both Windows and Linux operating systems, iSCSI boot can be configured to
boot with two distinctive paths: non-offload (also known as Microsoft/Open-iSCSI
initiator) and offload (Marvell’s offload iSCSI driver or Host Bus Adapter).
Configure the path with the HBA Boot Mode option located on the General
Parameters page of the iSCSI Configuration utility. See Table 10-1 on page 107
for more information on all General Parameters page configuration options.
NOTE
If you are using iSCSI boot on BCM57xxx based designs, SR-IOV must be
disabled in the system before upgrading from a 7.2.x (or earlier) release to
release 7.4.x or later.
