n Coredump is not supported on any software FCoE LUNs, including the boot LUN.<br />
n Multipathing is not supported at pre-boot.<br />
n Boot LUN cannot be shared with other hosts even on shared storage.<br />
Best Practices for Software FCoE Boot<br />
<strong>VMware</strong> recommends several best practices when you boot your system from a software FCoE LUN.<br />
n Make sure that the host has access to the entire boot LUN. The boot LUN cannot be shared with other<br />
hosts even on shared storage.<br />
n If you use Intel 10 Gigabit Ethernet Controller (Niantec) with a Cisco switch, configure the switch port in<br />
the following way:<br />
n Enable the Spanning Tree Protocol (STP).<br />
n Turn off switchport trunk native vlan for the VLAN used for FCoE.<br />
Set Up Software FCoE Boot<br />
Your <strong>ESXi</strong> host can boot from a FCoE LUN using the software FCoE adapter a network adapter.<br />
When you configure your host for a software FCoE boot, you perform a number of tasks.<br />
Prerequisites<br />
The network adapter has the following capabilities:<br />
n Support partial FCoE offload (software FCoE).<br />
n Contain either a FCoE Boot Firmware Table (FBFT) or a FCoE Boot Parameter Table (FBPT).<br />
For information about network adapters that support software FCoE boot, see the <strong>vSphere</strong> Compatibility<br />
Guide.<br />
Procedure<br />
1 Configure Software FCoE Boot Parameters on page 64<br />
To support a software FCoE boot process, a network adapter on your host must have a specially<br />
configured FCoE boot firmware. When you configure the firmware, you enable the adapter for the<br />
software FCoE boot and specify the boot LUN parameters.<br />
2 Install and Boot <strong>ESXi</strong> from Software FCoE LUN on page 65<br />
When you set up your system to boot from a software FCoE LUN, you install the <strong>ESXi</strong> image to the target<br />
LUN. You can then boot your host from that LUN.<br />
Configure Software FCoE Boot Parameters<br />
To support a software FCoE boot process, a network adapter on your host must have a specially configured<br />
FCoE boot firmware. When you configure the firmware, you enable the adapter for the software FCoE boot<br />
and specify the boot LUN parameters.<br />
Procedure<br />
u In the option ROM of the network adapter, specify software FCoE boot parameters.<br />
These parameters include boot target, boot LUN, VLAN ID, and so on.<br />
Because configuring the network adapter is vendor specific, review your vendor documentation for<br />
instructions.<br />
