Best scenario you would like to use is (and cheapest) :

Install Solaris 11.1 (do not install beta version), it will come with Oracle VM server for sparc on all physical nodes since you currently have multiple version of Solaris in production.

Check to have everything the same version on all physical hosts, this is important (firmware, Os version etc.)

Configure it, and create as much ldoms as you need and migrate your Solaris installations on it.
Oracle VM Server for SPARC Physical-to-Virtual Conversion Tool - Oracle VM Server for SPARC 3.1 Administration Guide

Requirement is to have FC or similar tech (NFS, ISCSI), so all the physical hosts see all the network disks and are logically configured with same names on all physical hosts.

This will enable you to live migrate a ldom from host to host with no downtime or import tje configuration of ldom and boot it on another host in case of failure (you will need to backup ldom xml configuration from all physical hosts on external location).

You can, of course, have local disks ldoms, but those are prone to single host failure, but such configuration can be used if you have SC between two ldoms on two physical hosts.

In the above example, you will not be using SC, for SC scenario is much alike but then clusterware is doing all the migrations and booting in case of failure or switching.

nca.if

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.
