Applies to:

Sun Solaris Volume Manager (SVM) - Version 11.9.0 to 11.10.0 [Release 11.0]

This document describes the steps to mirror the Solaris Operating System x86 boot disk
- using Solaris Volume Manager on Solaris 10 x86 Update 1 (1/06) release or later
The reason for this is that GRUB was introduced with Solaris 10 x86 Update 1 (1/06) release.

Earlier Solaris Versions are not covered by this document. For earlier Solaris versions than  Solaris 10 x86 Update 1 (1/06)  refer to Solaris Volume Manager Administration Guide

Boot disk mirroring with Solaris Volume Manager is no longer supported on Solaris 11.

Starting in the Solaris 10 10/08 Update6 release, you can install and boot from a ZFS root file system.
Details in Oracle Solaris ZFS Administration Guide - Installing and Booting an Oracle Solaris ZFS Root File System (Overview)
