Example of Upgrading With Solaris Live Upgrade (Command-Line Interface)

In this example, a new boot environment is created by using the lucreate command on a system that is running the Solaris 9 release. The new boot environment is upgraded to the Solaris 10 release by using the luupgrade command. The upgraded boot environment is activated by using the luactivate command. An example of falling back to the original boot environment is also given.

To Install Required Patches

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 –

Starting with the Solaris 1/06 release, 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 http://sunsolve.sun.com. Search for the info doc 72099 on the SunSolve web site.

If you are running the Solaris 8 or Solaris 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 that is 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 at http://sunsolve.sun.com.

Follow these steps to install the required patches.

From the SunSolve web site, obtain the list of patches.

To Create a Boot Environment

The source boot environment is named c0t4d0s0 by using the -c option. Naming the source boot environment is required only when the first boot environment is created. For more information about naming using the -c option, see the description in “To Create a Boot Environment for the First Time” Step 2.

The new boot environment is named c0t15d0s0. The -A option creates a description that is associated with the boot environment name.

The root (/) file system is copied to the new boot environment. Also, a new swap slice is created rather than sharing the source boot environment's swap slice.

# lucreate -A 'BE_description' -c c0t4d0s0 -m /:/dev/dsk/c0t15d0s0:ufs\
-m -:/dev/dsk/c0t15d0s1:swap -n c0t15d0s0

To Upgrade the Inactive Boot Environment

The inactive boot environment is named c0t15d0s0. The operating system image to be used for the upgrade is taken from the network.

# luupgrade -n c0t15d0s0 -u -s /net/ins-svr/export/Solaris_10 \ 
combined.solaris_wos

To Check if Boot Environment Is Bootable

The lustatus command reports if the boot environment creation is complete. lustatus also shows if the boot environment is bootable.

# lustatus
boot environment   Is        Active  Active     Can	    Copy
Name               Complete  Now	 OnReboot   Delete	 Status
------------------------------------------------------------------------
c0t4d0s0           yes       yes      yes      no      -
c0t15d0s0          yes       no       no       yes     -

To Activate the Inactive Boot Environment

The c0t15d0s0 boot environment is made bootable with the luactivate command. The system is then rebooted and c0t15d0s0 becomes the active boot environment. The c0t4d0s0 boot environment is now inactive.

# luactivate c0t15d0s0
# init 6

(Optional) To Fall Back to the Source Boot Environment

The following procedures for falling back depend on your new boot environment activation situation:

For SPARC based systems:
- The activation is successful, but you want to return to the original boot environment. See Example 12–1.
- The activation fails and you can boot back to the original boot environment. See Example 12–2.
- The activation fails and you must boot back to the original boot environment by using media or a net installation image. See Example 12–3.
For x86 based systems, starting with the Solaris 10 1/06 release and when you use the GRUB menu:
- The activation fails, the GRUB menu is displayed correctly, but the new boot environment is not bootable. See Example 12–4
- The activation fails and the GRUB menu does not display. See Example 12–5.

Example 12–1 SPARC: To Fall Back Despite Successful Boot Environment Creation

In this example, the original c0t4d0s0 boot environment is reinstated as the active boot environment although it was activated successfully. The device name is first_disk.

# /sbin/luactivate first_disk 
# init 6

Example 12–2 SPARC: To Fall Back From a Failed Boot Environment Activation

In this example, the new boot environment was not bootable. You must return to the OK prompt before booting from the original boot environment, c0t4d0s0, in single-user mode.

OK boot net -s
# /sbin/luactivate first_disk
Do you want to fallback to activate boot environment c0t4d0s0 
(yes or no)? yes
# init 6

The original boot environment, c0t4d0s0, becomes the active boot environment.

Example 12–3 SPARC: To Fall Back to the Original Boot Environment by Using a DVD, CD, or Net Installation Image

In this example, the new boot environment was not bootable. You cannot boot from the original boot environment and must use media or a net installation image. The device is /dev/dsk/c0t4d0s0. The original boot environment, c0t4d0s0, becomes the active boot environment.

OK boot net -s
# fsck /dev/dsk/c0t4d0s0
# mount /dev/dsk/c0t4d0s0 /mnt 
# /mnt/sbin/luactivate
Do you want to fallback to activate boot environment c0t4d0s0 
(yes or no)? yes
# umount /mnt 
# init 6

Example 12–4 x86: To Fall Back to the Original Boot Environment By Using the GRUB Menu

Starting with the Solaris 10 1/06 release, the following example provides the steps to fall back by using the GRUB menu.

In this example, the GRUB menu is displayed correctly, but the new boot environment is not bootable. To enable a fallback, the original boot environment is booted in single-user mode.

To display the GRUB menu, reboot the system.

# init 6

The GRUB menu is displayed.

From the GRUB menu, select the original boot environment. The boot environment must have been created with GRUB software. A boot environment that was created before the Solaris 10 1/06 release is not a GRUB boot environment. If you do not have a bootable GRUB boot environment, then skip to Example 12–5.
Edit the GRUB menu by typing: e.
Select kernel /boot/multiboot by using the arrow keys and type e. The grub edit menu is displayed.
grub edit>kernel /boot/multiboot
Boot to single user mode, by typing -s.
grub edit>kernel /boot/multiboot -s
Boot and mount the boot environment. Then activate it.

Example 12–5 x86: To Fall Back to the Original Boot Environment With the GRUB Menu by Using the DVD or CD

Starting with the Solaris 10 1/06 release, the following example provides the steps to fall back by using the DVD or CD.

In this example, the new boot environment was not bootable. Also, the GRUB menu does not display. To enable a fallback, the original boot environment is booted in single-user mode.

Insert the Solaris Operating System for x86 Platforms DVD or Solaris Software for x86 Platforms - 1 CD.

Boot from the DVD or CD.
