Chapter 10. Solaris Bare-Metal Recovery
Flash archive is a flexible, transportable, and easy-to-use utility that can perform
installation, cloning, and bare-metal recovery of Solaris
systems. Sun documentation presents this product primarily as a cloning and installation
tool. However, since you can create an image from a running operating system and then use
that image during a boot process to “install” that image to a vanilla system, it makes a
perfectly good bare-metal recovery tool, and that is what I focus on in this chapter. It can

mksysb command because it works
Flash archive eliminates all the limitations of the Solaris
ufsrestore utility, which required that all systems
have the same hardware, kernel, and device tree set up in order to perform
bare-metal recovery. Flash archive is
available for Solaris 8 and above, and is fully supported across the full line of Sun
servers using either 32- or 64-bit kernels.
