Last updated on JUNE 28, 2017
Applies to:Solaris Operating System - Version 10 3/05 HW2 to 10 1/13 U11 [Release 10.0]
Sun Solaris Volume Manager (SVM) - Version 11.9.0 to 11.10.0 [Release 11.0]
Oracle Solaris on x86-64 (64-bit)
This article describes the details of the x86 boot process, in particular as they relate to the choice of which disk is accessed during the various boot stages. The information in the article is based on Solaris 10 releases, beginning with Solaris 10 10/08 (Update 6), that use the findroot GRUB menu command. The root GRUB menu command can also be used. To use the root command, use the syntax described in Table 15-1 in "Chapter 15 x86: GRUB Based Booting" in System Administration Guide: Basic Administration, which you can view in HTML format or download in PDF format. The findroot command was introduced in Solaris 10 10/08 (Update 6) and requires that release or later. The root command can be used with any version of Solaris that uses GRUB.
The information is relevant to configurations that mirror the operating system (OS) with Solaris Volume Manager (SVM), but it is also of value in general to understand how an x86 system steps through the stages of the boot process. That is the main focus of the article.
