Upgrading a Boot Environment

After you have created a boot environment, you can perform an upgrade on the boot environment. As part of that upgrade, the boot environment can contain RAID-1 volumes (mirrors) for any file systems. The upgrade does not affect any files in the active boot environment. When you are ready, you activate the new boot environment, which then becomes the current boot environment.

• For procedures about upgrading a boot environment, see Chapter 36, Upgrading With Solaris Live Upgrade (Tasks).

• For an example of upgrading a boot environment with mirrored file systems, see Example of Detaching and Upgrading One Side of a RAID 1 Volume (Mirror) (Command-Line Interface).

Figure 33–6 shows an upgrade to an inactive boot environment.

Rather than an upgrade, you can install a Solaris Flash archive on a boot environment. The Solaris Flash installation feature enables you to create a single reference installation of the Solaris operating environment on a system. This system is called the master system. Then, you can replicate that installation on a number of systems that are called clone systems. In this situation, the inactive boot environment is a clone. When you install the Solaris Flash archive on a system, the archive replaces all the files on the existing boot environment as an initial installation would.

For procedures on installing a Solaris Flash archive, see Installing Solaris Flash Archives on a Boot Environment.

Figure 33–7 shows an installation of a Solaris Flash archive on an inactive boot environment.
