In this example, a new boot environment is created by using the lucreate command on a system that is running the Solaris 2.6 release. The new boot environment is upgraded to the Solaris 9 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.
Insert the Solaris 9 DVD or Solaris 9 Software 2 of 2 CD.
Follow the step for the media you are using.
If you are using the Solaris 9 DVD, change directories to the installer and run the installer.
# cd /cdrom/cdrom0/Solaris_9/Tools/Installers # ./liveupgrade20 |
The Solaris Web Start installer is displayed.
If you are using the Solaris 9 Software 2 of 2 CD, run the installer.
% ./installer |
The Solaris Web Start installer is displayed.
From the Select Type of Install panel, click Custom.
On the Locale Selection panel, click the language to be installed.
Choose the software to install.
For DVD, on the Component Selection panel, click Next to install the packages.
For CD, On the Product Selection panel, click Default Install for Solaris Live Upgrade and click on the other software choices to deselect them.
Follow the directions on the Solaris Web Start installer panels to install the software.
The source boot environment is named c0t4d0s0 by using the -c option. Naming the source boot environment is not required and is only used when the first boot environment is created. For more information on naming using the -c option, see the description in 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 |
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/ins3-svr/export/s9/combined.s9s_wos |
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 - |
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 |
Three procedures for falling back depend on your new boot environment activation situation:
The activation is successful, but you want to return to the original boot environment. See Example 35–1.
The activation fails and you can boot back to the original boot environment. See Example 35–2.
The activation fails and you must boot back to the original boot environment by using media or a net installation image. See Example 35–3.
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.
# /usr/sbin/luactivate first_disk # init 6 |
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.
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 |
