This chapter explains how to use Solaris Live Upgrade to upgrade and activate an inactive boot environment. This chapter contains the following sections:Task Map: Upgrading a Boot Environment Upgrading a Boot Environment Installing Solaris Flash Archives on a Boot Environment Activating a Boot Environment Task Description For Instructions Either upgrade a boot environment or install a Solaris Flash archive. Upgrade the inactive boot environment with an OS image. Install a Solaris Flash archive on an inactive boot environment. Upgrading a Boot Environment Installing Solaris Flash Archives on a Boot Environment Activate an inactive boot environment. Makes changes effective and switches the inactive boot environment to active . Activating a Boot Environment (optional) Switch back if a failure occurs when activating. Reactivates to the original boot environment if a failure occurs. Chapter 6, Failure Recovery: Falling Back to the Original Boot Environment (Tasks) Use the luupgrade command to upgrade a boot environment. This section provides the procedure for upgrading an inactive boot environment from files that are located on the following media:NFS server Local file Local tape Local device, including DVD or CD When you upgrade a boot environment with the latest OS, you do not affect the active boot environment. The new files merge with the inactive boot environment critical file systems, but shareable file systems are not changed.You can upgrade when RAID-1 volumes are installed, or if non-global zones are installed, or you can install a Solaris Flash:You can upgrade an inactive boot environment that contains any combination of physical disk slices, Solaris Volume Manager volumes, or Veritas Volume Manager volumes. The slice that is chosen for the root (/) file system must be a single-slice concatenation that is included in a RAID–1 volume (mirror). For procedures about creating a boot environment with mirrored file systems, see To Create a Boot Environment With RAID-1 Volumes (Mirrors).If VxVM volumes are configured on your current system, the lucreate command can create a new boot environment. When the data is copied to the new boot environment, the Veritas file system configuration is lost and a UFS file system is created on the new boot environment. You can upgrade a system that has non-global zones installed with any installation program. For procedures about upgrading with non-global zones, see Chapter 9, Upgrading the Solaris OS on a System With Non-Global Zones Installed. Rather than upgrading, if you have created a Solaris Flash archive, you could install the archive on an inactive boot environment. The new files overwrite critical file systems of the inactive boot environment, but shareable file systems are not changed. See Installing Solaris Flash Archives on a Boot Environment. You can use Solaris Live Upgrade to add patches and packages to a system. Solaris Live Upgrade creates a copy of the currently running system. This new boot environment can be upgraded or you can add packages or patches. When you use Solaris Live Upgrade, the only downtime the system incurs is that of a reboot. You can add patches and packages to a new boot environment with the luupgrade command.When adding and removing packages or patches, Solaris Live Upgrade requires packages or patches that comply with the SVR4 advanced packaging guidelines. While Sun packages conform to these guidelines, Sun cannot guarantee the conformance of packages from third-party vendors. If a package violates these guidelines, the package can cause the package-addition software to fail or alter the active boot environment during an upgrade. For more information about packaging requirements, see Appendix B, Additional SVR4 Packaging Requirements (Reference). Type of Installation Description For More Information Adding patches to a boot environment. Create a new boot environment and use the luupgrade command with the t option. To Add Patches to a Network Installation Image on a Boot Environment Adding packages to a boot environment. Use the luupgrade command with the p option. To Add Packages to a Network Installation Image on a Boot Environment To upgrade by using this procedure, you must use a DVD or a network installation image. If the installation requires more than one CD, you must use the procedure To Upgrade a Network Installation Image From Multiple CDs. Install the Solaris Live Upgrade SUNWlucfg, SUNWlur, and SUNWluu packages on your system. These packages must be from the release you are upgrading to. For step-by-step procedures, see To Install Solaris Live Upgrade With the pkgadd Command. &suStepA;Indicate the boot environment to upgrade and the path to the installation software by typing:# luupgrade -u -n BE_name -s os_image_pathuUpgrades a network installation image on a boot environment n BE_nameSpecifies the name of the boot environment that is to be upgraded s os_image_pathSpecifies the path name of a directory that contains a network installation image In this example, the second_disk boot environment is upgraded by using DVD media. The pkgadd command adds the Solaris Live Upgrade packages from the release you are upgrading to.# pkgadd -d /server/packages SUNWlucfg SUNWlur SUNWluu # luupgrade -u -n second_disk -s /media/cdrom/s0 In this example, the second_disk boot environment is upgraded. The pkgadd command adds the Solaris Live Upgrade packages from the release you are upgrading to.# pkgadd -d /server/packages SUNWlucfg SUNWlur SUNWluu # luupgrade -u -n second_disk \ -s /net/installmachine/export/Solaris_11/OS_image Because the network installation image resides on more than one CD, you must use this upgrade procedure. Use the luupgrade command with the i option to install any additional CDs. Install the Solaris Live Upgrade SUNWlucfg, SUNWlur, and SUNWluu packages on your system. These packages must be from the release you are upgrading to. For step-by-step procedures, see To Install Solaris Live Upgrade With the pkgadd Command. &suStepA;Indicate the boot environment to upgrade and the path to the installation software by typing:# luupgrade -u -n BE_name -s os_image_pathuUpgrades a network installation image on a boot environment n BE_nameSpecifies the name of the boot environment that is to be upgraded s os_image_pathSpecifies the path name of a directory that contains a network installation image When the installer is finished with the contents of the first CD, insert the second CD. This step is identical to the previous step, but the u option is replaced by the i option. Also, choose to run the installer on the second CD with menus or with text.This command runs the installer on the second CD with menus.# luupgrade -i -n BE_name -s os_image_path This command runs the installer on the second CD with text and requires no user interaction.# luupgrade -i -n BE_name -s os_image_path O 'nodisplay noconsole' iInstalls additional CDs. The software looks for an installation program on the specified medium and runs that program. The installer program is specified with s. n BE_nameSpecifies the name of the boot environment that is to be upgraded. s os_image_pathSpecifies the path name of a directory that contains an network installation image. O 'nodisplay noconsole'(Optional) Runs the installer on the second CD in text mode and requires no user interaction. Repeat Step 4 and Step 5 for each CD that you want to install.The boot environment is ready to be activated. See Activating a Boot Environment. In this example, the second_disk boot environment is upgraded and the installation image is on two CDs: the Solaris Software - 1 and the Solaris Software - 2 CDs. The u option determines if sufficient space for all the packages is on the CD set. The O option with the nodisplay and noconsole options prevents the character user interface from displaying after the reading of the second CD. If you use these options, you are not prompted to type information.Note: If you do not use the O option with the nodisplay and noconsole options, the character user interface (CUI) is displayed. Sun no longer recommends using the (CUI) to do Solaris Live Upgrade tasks.Install the Solaris Live Upgrade packages from the release you are upgrading to.# pkgadd -d /server/packages SUNWlucfg SUNWlur SUNWluuInsert the Solaris Software - 1 CD and type:For SPARC based systems:# luupgrade -u -n second_disk -s /media/cdrom/s0 For x86 based systems:# luupgrade -u -n second_disk -s /media/cdrom/ Insert the Solaris Software - 2 CD and type the following.# luupgrade -i -n second_disk -s /media/cdrom -O '-nodisplay \ -noconsole' Repeat this step for each CD that you need.Repeat the previous step for each CD that you want to install. In the following procedure, packages are removed from and added to a new boot environment.When you are upgrading. adding and removing packages or patches, Solaris Live Upgrade requires packages or patches that comply with the SVR4 advanced packaging guidelines. While Sun packages conform to these guidelines, Sun cannot guarantee the conformance of packages from third-party vendors. If a package violates these guidelines, the package can cause the package-addition software to fail or can alter the active boot environment.For more information about packaging requirements, see Appendix B, Additional SVR4 Packaging Requirements (Reference). &suStepA;To remove a package or set of packages from a new boot environment, type:# luupgrade -P -n second_disk package-namePIndicates to remove the named package or packages from the boot environment n BE_nameSpecifies the name of the boot environment where the package is to be removed package-nameSpecifies the names of the packages to be removed. Separate multiple package names with spaces. To add a package or a set of packages to the new boot environment, type:# luupgrade -p -n second_disk -s /path-to-packages package-namepIndicates to add packages to the boot environment. n BE_nameSpecifies the name of the boot environment where the package is to be added. s path-to-packagesSpecifies the path to a directory that contains the package or packages that are to be added. package-nameSpecifies the names of the package or packages to be added. Separate multiple package names with a space. In this example, packages are removed then added to the second_disk boot environment.# luupgrade -P -n second_disk SUNWabc SUNWdef SUNWghi # luupgrade -p -n second_disk -s /net/installmachine/export/packages \ SUNWijk SUNWlmn SUNWpkr In the following procedure, patches are removed from and added to a new boot environment.When you are adding and removing packages or patches, Solaris Live Upgrade requires packages or patches that comply with the SVR4 advanced packaging guidelines. While Sun packages conform to these guidelines, Sun cannot guarantee the conformance of packages from third-party vendors. If a package violates these guidelines, the package can cause the package-addition software to fail or can alter the active boot environment. &suStepA;To remove a patch or set of patches from a new boot environment, type:# luupgrade -T -n second_disk patch_nameTIndicates to remove the named patch or patches from the boot environment. n BE_nameSpecifies the name of the boot environment where the patch or patches are to be removed. patch-nameSpecifies the names of the patches to be removed.

Separate multiple patch names with a space. In this example, patches are removed then added to the second_disk boot environment .# luupgrade -T -n second_disk 222222-01 # luupgrade -t -n second_disk -s /net/installmachine/export/packages \ 333333-01 4444444-01 The follow procedure checks the integrity of the packages installed on the new boot environment. &suStepA;To check the integrity of the newly installed packages on the new boot environment, type:# luupgrade -C -n second_disk -O "-v" package-nameCIndicates to run the pkgchk command on the named packages n BE_nameSpecifies the name of the boot environment where the check is to be performed OPasses the options directly to the pkgchk command package-nameSpecifies the names of the packages to be checked. Separate multiple package names with spaces. If package names are omitted, the check is done on all packages in the specified boot environment. “v”Specifies to run the command in verbose mode In this example, the packages SUNWabc, SUNWdef, and SUNWghi are checked to make sure they were installed properly and are not damaged.# luupgrade -C -n second_disk SUNWabc SUNWdef SUNWghi You can create a JumpStart profile to use with Solaris Live Upgrade. If you are familiar with the custom JumpStart program, this is the same profile that custom JumpStart uses. The following procedures enable you to create a profile, test the profile, and install by using the luupgrade command with the j option.When you install the Solaris OS with a Solaris Flash archive, the archive and the installation media must contain identical OS versions. For example, if the archive is the Solaris 10 operating system and you are using DVD media, then you must use Solaris 10 DVD media to install the archive. If the OS versions do not match, the installation on the target system fails. Identical operating systems are necessary when you use the following keyword or command:archive_location keyword in a profile luupgrade command with s, a, j, and J options For more information see the following:To Create a Profile to be Used by Solaris Live Upgrade To Test a Profile to Be Used by Solaris Live Upgrade To Upgrade With a Profile by Using Solaris Live Upgrade For creating a JumpStart profile, see Creating a Profile in Solaris Express Installation Guide: Custom JumpStart and Advanced Installations This procedure shows you how to create a profile for use with Solaris Live Upgrade. You can use this profile to upgrade an inactive boot environment by using the luupgrade command with the j option. For procedures to use this profile, see the following sections:For an upgrade with a profile, see To Upgrade With a Profile by Using Solaris Live Upgrade. For a Solaris Flash installation with a profile, see To Install a Solaris Flash Archive With a Profile. Use a text editor to create a text file. Name the file descriptively. Ensure that the name of the profile reflects how you intend to use the profile to install the Solaris software on a system. For example, you might name this profile upgrade_Solaris_11. Add profile keywords and values to the profile.Only the upgrade keywords in the following tables can be used in a Solaris Live Upgrade profile. The following table lists the keywords you can use with the Install_type keyword values of upgrade or flash_install.Keywords for an Initial Archive Creation Description Reference (Required) Install_type Defines whether to upgrade the existing Solaris environment on a system or install a Solaris Flash archive on the system. Use the following values with this keyword:upgrade for an upgrade flash_install for a Solaris Flash installation flash_update for a Solaris Flash differential installation For a description of all the values for this keyword, see install_type Profile Keyword in Solaris Express Installation Guide: Custom JumpStart and Advanced Installations. (Required for a Solaris Flash archive) archive_location Retrieves a Solaris Flash archive from a designated location. For a list of values that can be used with this keyword, see archive_location Keyword in Solaris Express Installation Guide: Custom JumpStart and Advanced Installations. (Optional) cluster (adding or deleting clusters) Designates whether a cluster is to be added or deleted from the software group that is to be installed on the system. For a list of values that can be used with this keyword, see cluster Profile Keyword (Adding Software Groups) in Solaris Express Installation Guide: Custom JumpStart and Advanced Installations. (Optional) geo Designates the regional locale or locales that you want to install on a system or to add when upgrading a system. For a list of values that can be used with this keyword, see geo Profile Keyword in Solaris Express Installation Guide: Custom JumpStart and Advanced Installations. (Optional) local_customization Before you install a Solaris Flash archive on a clone system, you can create custom scripts to preserve local configurations on the clone system. The local_customization keyword designates the directory where you have stored these scripts. The value is the path to the script on the clone system. For information about predeployment and postdeployment scripts, see Creating Customization Scripts in Solaris Express Installation Guide: Solaris Flash Archives (Creation and Installation). (Optional) locale Designates the locale packages you want to install or add when upgrading. For a list of values that can be used with this keyword, see locale Profile Keyword in Solaris Express Installation Guide: Custom JumpStart and Advanced Installations. (Optional) package Designates whether a package is to be added to or deleted from the software group that is to be installed on the system. For a list of values that can be used with this keyword, see package Profile Keyword in Solaris Express Installation Guide: Custom JumpStart and Advanced Installations. The following table lists the keywords you can use with the Install_type keyword value flash_update.Keywords for a Differential Archive Creation Description Reference (Required) Install_type Defines the installation to install a Solaris Flash archive on the system. The value for a differential archive is flash_update. For a description of all the values for this keyword, see install_type Profile Keyword in Solaris Express Installation Guide: Custom JumpStart and Advanced Installations. (Required) archive_location Retrieves a Solaris Flash archive from a designated location. For a list of values that can be used with this keyword, see archive_location Keyword in Solaris Express Installation Guide: Custom JumpStart and Advanced Installations. (Optional) forced_deployment Forces the installation of a Solaris Flash differential archive onto a clone system that is different than the software expects. If you use forced_deployment, all new files are deleted to bring the clone system to the expected state. If you are not certain that you want files to be deleted, use the default, which protects new files by stopping the installation. For more information about this keyword, see forced_deployment Profile Keyword (Installing Solaris Flash Differential Archives) in Solaris Express Installation Guide: Custom JumpStart and Advanced Installations. (Optional) local_customization Before you install a Solaris Flash archive on a clone system, you can create custom scripts to preserve local configurations on the clone system. The local_customization keyword designates the directory where you have stored these scripts. The value is the path to the script on the clone system. For information about predeployment and postdeployment scripts, see Creating Customization Scripts in Solaris Express Installation Guide: Solaris Flash Archives (Creation and Installation). (Optional) no_content_check When installing a clone system with a Solaris Flash differential archive, you can use the no_content_check keyword to ignore file-by-file validation. File-by-file validation ensures that the clone system is a duplicate of the master system. Avoid using this keyword unless you are sure the clone system is a duplicate of the original master system. For more information about this keyword, see no_content_check Profile Keyword (Installing Solaris Flash Archives) in Solaris Express Installation Guide: Custom JumpStart and Advanced Installations. (Optional) no_master_check When installing a clone system with a Solaris Flash differential archive, you can use the no_master_check keyword to ignore a check of files. Clone system files are not checked. A check would ensure the clone was built from the original master system. Avoid using this keyword unless you are sure the clone system is a duplicate of the original master system. For more information about this keyword, see no_master_check Profile Keyword (Installing Solaris Flash Archives) in Solaris Express Installation Guide: Custom JumpStart and Advanced Installations. Save the profile in a directory on the local system. Ensure that root owns the profile and that the permissions are set to 644. Test the profile (optional).For a procedure to test the profile, see To Test a Profile to Be Used by Solaris Live Upgrade. In this example, a profile provides the upgrade parameters. This profile is to be used to upgrade an inactive boot environment with the Solaris Live Upgrade luupgrade command and the u and j options. This profile adds a package and a cluster. A regional locale and additional locales are also added to the profile. If you add locales to the profile, make sure that you have created a boot environment with additional disk space. # profile keywords profile values # ---------------- ------------------- install_type upgrade package SUNWxwman add cluster SUNWCacc add geo C_Europe locale zh_TW locale zh_TW.BIG5 locale zh_TW.UTF-8 locale zh_HK.UTF-8 locale zh_HK.BIG5HK locale zh locale zh_CN.GB18030 locale zh_CN.GBK locale zh_CN.UTF-8 The following example of a profile is to be used by Solaris Live Upgrade to install a differential archive on a clone system. Only files that are specified by the differential archive are added, deleted, or changed. The Solaris Flash archive is retrieved from an NFS server. Because the image was built by the original master system, the clone system is not checked for a valid system image. This profile is to be used with the Solaris Live Upgrade luupgrade command and the u and j options.# profile keywords profile values # ---------------- ------------------- install_type flash_update archive_location nfs installserver:/export/solaris/archive/solarisarchive no_master_checkTo use the luupgrade command to install the differential archive, see To Install a Solaris Flash Archive With a Profile. After you create a profile, use the luupgrade command to test the profile. By looking at the installation output that is generated by luupgrade, you can quickly determine if a profile works as you intended. &suStepA;Test the profile.# luupgrade -u -n BE_name -D -s os_image_path -j profile_pathuUpgrades an operating system image on a boot environment. n BE_nameSpecifies the name of the boot environment that is to be upgraded. Dluupgrade command uses the selected boot environment's disk configuration to test the profile options that are passed with the j option. s os_image_pathSpecifies the path name of a directory that contains an operating system image. This directory can be on an installation medium, such as a DVD-ROM, CD-ROM, or it can be an NFS or UFS directory. j profile_pathPath to a profile that is configured for an upgrade. The profile must be in a directory on the local machine. In the following example, the profile is named Flash_profile. The profile is successfully tested on the inactive boot environment that is named second_disk. # luupgrade -u -n u1b08 -D -s /net/installsvr/export/u1/combined.u1wos \ -j /var/tmp/flash_profile Validating the contents of the media /net/installsvr/export/u1/combined.u1wos. The media is a standard Solaris media. The media contains an operating system upgrade image. The media contains Solaris version 10. Locating upgrade profile template to use. Locating the operating system upgrade program. Checking for existence of previously scheduled Live Upgrade requests. Creating upgrade profile for BE second_disk. Determining packages to install or upgrade for BE second_disk. Simulating the operating system upgrade of the BE second_disk. The operating system upgrade simulation is complete. INFORMATION: var/sadm/system/data/upgrade_cleanup contains a log of the upgrade operation. INFORMATION: var/sadm/system/data/upgrade_cleanup contains a log of cleanup operations required. The Solaris upgrade of the boot environment second_disk is complete.You can now use the profile to upgrade an inactive boot environment. This procedure provides step-by-step instructions for upgrading an OS by using a profile.If you want to install a Solaris Flash archive by using a profile, see To Install a Solaris Flash Archive With a Profile.If you added locales to the profile, make sure that you have created a boot environment with additional disk space.When you install the Solaris OS with a Solaris Flash archive, the archive and the installation media must contain identical OS versions. For example, if the archive is the Solaris 10 operating system and you are using DVD media, then you must use Solaris 10 DVD media to install the archive. If the OS versions do not match, the installation on the target system fails. Identical operating systems are necessary when you use the following keyword or command:archive_location keyword in a profile luupgrade command with s, a, j, and J options Install the Solaris Live Upgrade SUNWlucfg, SUNWlur, and SUNWluu packages on your system. These packages must be from the release you are upgrading to. For step-by-step procedures, see To Install Solaris Live Upgrade With the pkgadd Command. &suStepA;Create a profile. See To Create a Profile to be Used by Solaris Live Upgrade for a list of upgrade keywords that can be used in a Solaris Live Upgrade profile. Type:# luupgrade -u -n BE_name -s os_image_path -j profile_pathuUpgrades an operating system image on a boot environment. n BE_nameSpecifies the name of the boot environment that is to be upgraded. s os_image_pathSpecifies the path name of a directory that contains an operating system image. This directory can be on an installation medium, such as a DVD-ROM, CD-ROM, or it can be an NFS or UFS directory. j profile_pathPath to a profile. The profile must be in a directory on the local machine. For information about creating a profile, see To Create a Profile to be Used by Solaris Live Upgrade. In this example, the second_disk boot environment is upgraded by using a profile. The j option is used to access the profile. The boot environment is then ready to be activated. To create a profile, see To Create a Profile to be Used by Solaris Live Upgrade. The pkgadd command adds the Solaris Live Upgrade packages from the release you are upgrading to.# pkgadd -d /server/packages SUNWlucfg SUNWlur SUNWluu # luupgrade -u -n second_disk \ -s /net/installmachine/export/solarisX/OS_image \ -j /var/tmp/profile The boot environment is ready to be activated. See Activating a Boot Environment. This section provides the procedure for using Solaris Live Upgrade to install Solaris Flash archives. Installing a Solaris Flash archive overwrites all files on the new boot environment except for shared files. Archives are stored on the following media:HTTP server FTP server – Use this path from the command line only NFS server Local file Local tape Local device, including DVD or CD Note the following issues with installing and creating a Solaris Flash archive.Description Example When you install the Solaris OS with a Solaris Flash archive, the archive and the installation media must contain identical OS versions. If the OS versions do not match, the installation on the target system fails. Identical operating systems are necessary when you use the following keyword or command: archive_location keyword in a profile luupgrade command with s, a, j, and J options For example, if the archive is the Solaris 10 operating system and you are using DVD media, then you must use Solaris 10 DVD media to install the archive. A Solaris Flash archive cannot be properly created when a non-global zone is installed. The Solaris Flash feature is not compatible with the Solaris Zones feature. If you create a Solaris Flash archive in a non-global zone or create an archive in a global zone that has non-global zones installed, the resulting archive does not install properly when the archive is deployed. Description For More Information For examples of the correct syntax for paths that are associated with archive storage. See archive_location Keyword in Solaris Express Installation Guide: Custom JumpStart and Advanced Installations. To use the Solaris Flash installation feature, you install a master system and create the Solaris Flash archive. For more information about creating an archive, see Chapter 3, Creating Solaris Flash Archives (Tasks), in Solaris Express Installation Guide: Solaris Flash Archives (Creation and Installation). Install the Solaris Live Upgrade SUNWlucfg, SUNWlur, and SUNWluu packages on your system. These packages must be from the release you are upgrading to.

You can also switch back quickly to the original boot environment if a failure occurs on booting the newly active boot environment. See Chapter 6, Failure Recovery: Falling Back to the Original Boot Environment (Tasks).Description For More Information Use this procedure to activate a boot environment with the luactivate command. The first time you activate a boot environment, the luactivate command must be used. To Activate a Boot Environment Use this procedure to activate a boot environment and force a synchronization of files. Files are synchronized with the first activation. If you switch boot environments after the first activation, files are not synchronized. To Activate a Boot Environment and Synchronize Files x86: Use this procedure to activate a boot environment with the GRUB menu.A GRUB menu can facilitate switching from one boot environment to another. A boot environment appears in the GRUB menu after the first activation. To Activate a Boot Environment With the GRUB Menu To successfully activate a boot environment, that boot environment must meet the following conditions:Description For More Information The boot environment must have a status of “complete.” To check status, see Displaying the Status of All Boot Environments If the boot environment is not the current boot environment, you cannot have mounted the partitions of that boot environment by using the luumount or mount commands. To view man pages, see lumount1M or mount1M The boot environment that you want to activate cannot be involved in a comparison operation. For procedures, see Comparing Boot Environments If you want to reconfigure swap, make this change prior to booting the inactive boot environment. By default, all boot environments share the same swap devices. To reconfigure swap, see To Create a Boot Environment and Reconfiguring Swap If you have an x86 based system, you can also activate with the GRUB menu. Note the following exceptions:If a boot environment was created with the Solaris 8, 9, or 10 3/05 release, the boot environment must always be activated with the luactivate command. These older boot environments do not display on the GRUB menu. The first time you activate a boot environment, you must use the luactivate command. The next time you boot, that boot environment's name is displayed in the GRUB main menu. You can thereafter switch to this boot environment by selecting the appropriate entry in the GRUB menu. See Activating a Boot Environment With the GRUB Menu. The following procedure switches a new boot environment to become the currently running boot environment.If you have an x86 based system, you can also activate with the GRUB menu. Note the following exceptions:If a boot environment was created with the Solaris 8, 9, or 10 3/05 release, the boot environment must always be activated with the luactivate command. These older boot environments do not display on the GRUB menu. The first time you activate a boot environment, you must use the luactivate command. The next time you boot, that boot environment's name is displayed in the GRUB main menu. You can thereafter switch to this boot environment by selecting the appropriate entry in the GRUB menu. See Activating a Boot Environment With the GRUB Menu. &suStepA;To activate the boot environment, type:# /sbin/luactivate BE_nameBE_nameSpecifies the name of the boot environment that is to be activated Reboot.# init 6Use only the init or shutdown commands to reboot. If you use the reboot, halt, or uadmin commands, the system does not switch boot environments. The last-active boot environment is booted again. In this example, the second_disk boot environment is activated at the next reboot.# /sbin/luactivate second_disk # init 6 The first time you boot from a newly created boot environment, Solaris Live Upgrade software synchronizes the new boot environment with the boot environment that was last active. “Synchronize” means that certain critical system files and directories are copied from the last-active boot environment to the boot environment being booted. Solaris Live Upgrade does not perform this synchronization after the initial boot, unless you force synchronization with the luactivate command and the s option.When you switch between boot environments with the GRUB menu, files also are not synchronized. You must use the following procedure to synchronize files. For more information about synchronization, see Synchronizing Files Between Boot Environments. &suStepA;To activate the boot environment, type:# /sbin/luactivate -s BE_namesForces a synchronization of files between the last-active boot environment and the new boot environment. The first time that a boot environment is activated, the files between the boot environment are synchronized With subsequent activations, the files are not synchronized unless you use the s option.Use this option with great care, because you might not be aware of or in control of changes that might have occurred in the last-active boot environment. For example, if you were running Solaris Express 5/07 software on your current boot environment and booted back to a Solaris 9 release with a forced synchronization, files could be changed on the Solaris 9 release. Because files are dependent on the release of the OS, the boot to the Solaris 9 release could fail because the Solaris Express 5/07 files might not be compatible with the Solaris 9 files. BE_nameSpecifies the name of the boot environment that is to be activated. Reboot.# init 6 In this example, the second_disk boot environment is activated at the next reboot and the files are synchronized.# /sbin/luactivate -s second_disk # init 6 A GRUB menu provides an optional method of switching between boot environments. The GRUB menu is an alternative to activating (booting) with the luactivate command. The table below notes cautions and limitations when using the GRUB menu.Task Description For More Information Caution After you have activated a boot environment, do not change the disk order in the BIOS. Changing the order might cause the GRUB menu to become invalid. If this problem occurs, changing the disk order back to the original state fixes the GRUB menu. Activating a boot environment for the first time The first time you activate a boot environment, you must use the luactivate command. The next time you boot, that boot environment's name is displayed in the GRUB main menu. You can thereafter switch to this boot environment by selecting the appropriate entry in the GRUB menu. To Activate a Boot Environment Synchronizing files The first time you activate a boot environment, files are synchronized between the current boot environment and the new boot environment. With subsequent activations, files are not synchronized. When you switch between boot environments with the GRUB menu, files also are not synchronized. You can force a synchronization when using the luactivate command with the s option. To Activate a Boot Environment and Synchronize Files Boot environments created before the Solaris 10 1/06 release If a boot environment was created with the Solaris 8, 9, or 10 3/05 release, the boot environment must always be activated with the luactivate command. These older boot environments do not display on the GRUB menu. To Activate a Boot Environment Editing or customizing the GRUB menu entries The menu.lst file contains the information that is displayed in the GRUB menu. You can revise this file for the following reasons:To add to the GRUB menu entries for operating systems other than the Solaris OS. To customize booting behavior. For example, you could change booting to verbose mode or change the default time that automatically boots the OS. If you want to change the GRUB menu, you need to locate the menu.lst file. For step-by-step instructions, see Locating the GRUB Menu's menu.lst File (Tasks). Do not use the GRUB menu.lst file to modify Solaris Live Upgrade entries. Modifications could cause Solaris Live Upgrade to fail. Although you can use the menu.lst file to customize booting behavior, the preferred method for customization is to use the eeprom command. If you use the menu.lst file to customize, the Solaris OS entries might be modified during a software upgrade. Changes to the file could be lost. GRUB Based Booting (Overview) in Solaris Express Installation Guide: Planning for Installation and Upgrade Chapter 12, Booting a Solaris System With GRUB (Tasks), in System Administration Guide: Basic Administration You can switch between two boot environments with the GRUB menu. Note the following limitations:The first activation of a boot environment must be done with the luactivate command. After the initial activation, the boot environment is displayed on the GRUB menu. The boot environment can then be booted from the GRUB menu. Caution - Switching to a boot environment with the GRUB menu bypasses synchronization. For more information about synchronizing files, see link Forcing a Synchronization Between Boot Environments. If a boot environment was created with the Solaris 8, 9, or 10 3/05 release, the boot environment must always be activated with the luactivate command. These older boot environments are not displayed on the GRUB menu. &suStepA;Reboot the system.# init 6The GRUB main menu is displayed. The two operating systems are listed, Solaris and second_disk, which is a Solaris Live Upgrade boot environment. The failsafe entries are for recovery, if for some reason the primary OS does not boot.GNU GRUB version 0.95 (616K lower / 4127168K upper memory) +-------------------------------------------------------------------+ |Solaris | |Solaris failsafe | |second_disk | |second_disk failsafe | +-------------------------------------------------------------------+ Use the ^ and v keys to select which entry is highlighted. Press enter to boot the selected OS, 'e' to edit the commands before booting, or 'c' for a command-line. To activate a boot environment, use the arrow key to select the desired boot environment and press Return.The selected boot environment is booted and becomes the active boot environment.
