Supported Operating Systems for iSCSI Boot
The Marvell BCM57xx and BCM57xxx gigabit Ethernet adapters support iSCSI
boot on the following operating systems:
 Windows Server 2012 and later 32-bit and 64-bit (supports offload and
non-offload paths)
 Linux RHEL 6 and later and SLES 11.1 and later (supports offload and
non-offload paths)
 SLES 10.x and SLES 11 (only supports non-offload path)
 VMware ESXi 5.0 and later for IPv4 (supports only non-offload path), and
ESXi 6.0 and later for IPv6.
 VMware ESX in Layer 2 path
In addition, the adapters support iSCSI boot for unspecified path types on
supported Windows (see “Microsoft Windows” on page 18), RHEL (see “Linux” on
page 18), and Linux (“Linux” on page 18) OSs.
Jumbo frames with iSCSI boot are supported only on Windows OSs, when the
adapter is used as either an NDIS or HBA offload device.
iSCSI Boot Setup
The iSCSI boot setup includes:
 Configuring the iSCSI Target
 Configuring iSCSI Boot Parameters
 Preparing the iSCSI Boot Image
 Booting
Configuring the iSCSI Target
Configuring the iSCSI target varies by target vendors. For information on
configuring the iSCSI target, refer to the documentation provided by the vendor.
The general steps include:
1. Create an iSCSI target.
2. Create a virtual disk.
3. Map the virtual disk to the iSCSI target created in Step 1.
4. Associate an iSCSI initiator with the iSCSI target.
5. Record the iSCSI target name, TCP port number, iSCSI LUN, initiator
Internet Qualified Name (IQN), and CHAP authentication details.
6. After configuring the iSCSI target, obtain the following:
