Redundant IP interfaces for ISCSI boot?
I'm building a Solaris 11 OVM environment and want to configure everything to boot from our high performance SAN (no local disks). I've got everything working and the system boots nicely via an OBP configuration however I'd like to configure redundant IP interfaces within Solaris, what I'm struggling with is trying to create a redundant interface pair when one of my interfaces is configured as the boot interface, I've not found any documentation covering this despite this being an install option for Solaris 11.
Any ideas?

nca.if(4) File Formats nca.if(4)
NAME
nca.if - the NCA configuration file that specifies physical interfaces
SYNOPSIS
/etc/nca/nca.if
DESCRIPTION
Specify the physical interfaces for which the Solaris Network Cache and Accelerator ("NCA") feature will be configured in the nca.if con-
figuration file. List the physical interfaces in the file, one per line. To configure NCA to listen on all physical interfaces present on
the system backed by a hostname.{interface_name}, then list only an asterik ("*") in nca.if.
When the ncakmod(1) initialization script is invoked during system boot, it will attempt to configure each physical interface specified in
the nca.if file by using ncaconfd(1M). Note that there must be an accompanying hostname.{interface_name} file and an entry in /etc/hosts
for the contents of hostname.{interface_name}.
You must reboot in order to implement changes to the nca.if file.
EXAMPLES
x86
Example 1: nca.if on x86
The following is an example of an nca.if file that would be used on an x86 system:
iprb1
iprb6
iprb8
SPARC
Example 2: nca.if on SPARC
The following is an example of an nca.if file that would be used on a SPARC system:
hme2
hme3
hme4
All Platforms
Example 3: Configuring NCA to Listen on All Physical Interfaces
The following example shows the contents of an nca.if file that would be used to configure either platform to listen on all physical inter-
faces present on the system:
*
FILES
/etc/nca/nca.if Lists the physical interfaces on which NCA will run.
/etc/hostname.{}{0-9} Lists all physical interfaces configured on the server.
/etc/hosts Lists all host names associated with the server. Entries in this file must match with entries in /etc/host-
name.{}{0-9} for NCA to function.
