Solaris Live Upgrade Requirements
Before you install and use Solaris Live Upgrade, become familiar with these requirements.
Solaris Live Upgrade System Requirements
Solaris Live Upgrade is included in the Solaris software. You need to install
the Solaris Live Upgrade packages on your current OS. The release of the
Solaris Live Upgrade packages must match the release of the OS you are
upgrading to. For example, if your current OS is the Solaris 9
release and you want to upgrade to the Solaris Express 5/07 release, you
need to install the Solaris Live Upgrade packages from the Solaris Express 5/07
release.
Table 3-1 lists releases that are supported by Solaris Live Upgrade.

Installing Solaris Live Upgrade
You can install the Solaris Live Upgrade packages by using the following:
The pkgadd command. The Solaris Live Upgrade packages are SUNWlucfg, SUNWlur, and SUNWluu, and these packages must be installed in that order.
An installer on the Solaris Operating System DVD, the Solaris Software - 2 CD, or a network installation image.
Be aware that the following patches might need to be installed for
the correct operation of Solaris Live Upgrade.
Description |
For More Information |

Caution: Correct operation of Solaris Live
Upgrade requires that a limited set of patch revisions be installed for a
particular OS version. Before installing or running Solaris Live Upgrade, you are required
to install these patches.
x86 only - If this set of patches is not installed,
Solaris Live Upgrade fails and you might see the following error message. If
you don't see the following error message, necessary patches still might not be
installed. Always verify that all patches listed on the SunSolve info doc have
been installed before attempting to install Solaris Live Upgrade. ERROR: Cannot find or is not executable:
</sbin/biosdev>.
ERROR: One or more patches required
by Live Upgrade has not been installed.
The patches listed in info
doc 72099 are subject to change at any time. These patches potentially fix
defects in Solaris Live Upgrade, as well as fix defects in components that
Solaris Live Upgrade depends on. If you experience any difficulties with Solaris Live
Upgrade, please check and make sure that you have the latest Solaris Live
Upgrade patches installed. |
Ensure that you have the most recently updated patch list
by consulting https://sunsolve.sun.com. Search for the info doc 72099 on the SunSolve web
site. |
If you are running the Solaris 8 or 9 OS, you might
not be able to run the Solaris Live Upgrade installer. These releases
do not contain the set of patches needed to run the Java 2
runtime environment. You must have the recommended patch cluster for the Java 2
runtime environment recommended to run the Solaris Live Upgrade installer and install the
packages. |
To install the Solaris Live Upgrade packages, use the pkgadd command. Or install,
for the Java 2 runtime environment, the recommended patch cluster. The patch cluster
is available on https://sunsolve.sun.com. |
For instructions about installing the Solaris Live Upgrade software, see Installing Solaris Live Upgrade.
Required Packages
If you have problems with Solaris Live Upgrade, you might be missing packages.
In the following table, check that your OS has the listed packages ,
which are required to use Solaris Live Upgrade.
For the Solaris 10 release:
If you install one of the following software groups, these software groups contain all the required Solaris Live Upgrade packages.
Entire Solaris Software Group Plus OEM Support
Entire Solaris Software Group
Developer Solaris Software Group
End User Solaris Software Group
If you install one of these Software Groups, then you might not have all the packages required to use Solaris Live Upgrade.
For information about software groups, see Disk Space Recommendations for Software Groups in Solaris Express Installation Guide: Planning for Installation and Upgrade.

Solaris Live Upgrade Disk Space Requirements
Follow general disk space requirements for an upgrade. See Chapter 4, System Requirements, Guidelines, and Upgrade (Planning), in Solaris Express Installation Guide: Planning for Installation and Upgrade.
To estimate the file system size that is needed to create a boot
environment, start the creation of a new boot environment. The size is calculated.
You can then abort the process.
The disk on the new boot environment must be able to serve
as a boot device. Some systems restrict which disks can serve as a
boot device. Refer to your system's documentation to determine if any boot restrictions
apply.
The disk might need to be prepared before you create the new
boot environment. Check that the disk is formatted properly:
Identify slices large enough to hold the file systems to be copied.
Identify file systems that contain directories that you want to share between boot environments rather than copy. If you want a directory to be shared, you need to create a new boot environment with the directory put on its own slice. The directory is then a file system and can be shared with future boot environments. For more information about creating separate file systems for sharing, see Guidelines for Selecting Slices for Shareable File Systems.
Solaris Live Upgrade Requirements if Creating RAID-1 Volumes (Mirrors)
Solaris Live Upgrade uses Solaris Volume Manager technology to create a boot environment
that can contain file systems that are RAID-1 volumes (mirrors). Solaris Live Upgrade
does not implement the full functionality of Solaris Volume Manager, but does require
the following components of Solaris Volume Manager.
Table 3-3 Required Components for Solaris Live Upgrade and RAID-1 Volumes
Requirement |
Description |
For More Information |
|---|
You must create at
least one state database and at least three state database replicas. |
A state
database stores information about disk about the state of your Solaris Volume Manager
configuration. The state database is a collection of multiple, replicated database copies. Each
copy is referred to as a state database replica. When a state database
is copied, the replica protects against data loss from single points of failure. |
For information about creating a state database, see Chapter 6, State Database (Overview), in Solaris Volume Manager Administration Guide. |
Solaris Live Upgrade supports
only a RAID-1 volume (mirror) with single-slice concatenations on the root (/) file
system. |
A concatenation is a RAID-0 volume. If slices are concatenated, the data is
written to the first available slice until that slice is full. When that
slice is full, the data is written to the next slice, serially.
A concatenation provides no data redundancy unless it is contained in a RAID-1
volume A RAID—1 volume can be comprised of a maximum of three concatenations.
