Refer to Required Software and Patches in Oracle VM Server for SPARC 3.1.1 and 3.1 Release Notes to find the Oracle Solaris 10 or Oracle Solaris 11 OS that you should use for this version of the Oracle VM Server for SPARC software, and the required and recommended patches for the different domains. Refer to the Oracle Solaris 10 and Oracle Solaris 11 installation guides for complete instructions on upgrading the Oracle Solaris OS.
When reinstalling the Oracle Solaris OS in the control domain, you must save and restore the domain autosave configuration data and the constraints database file, as described in this section.
You can save and restore autosave configuration directories prior to reinstalling the operating system on the control domain. Whenever you reinstall the operating system on the control domain, you must save and restore the domain autosave configuration data, which is found in the /var/opt/SUNWldm/autosave-autosave-name directories.
You can use the tar or cpio command to save and restore the entire contents of the directories.
For more information about autosave configurations, see Managing Domain Configurations.
# cd / # tar -cvpf autosave.tar var/opt/SUNWldm/autosave-*
Sometimes an autosave directory might include extraneous files, perhaps left over from a previous configuration, that might corrupt the configuration that was downloaded to the SP. In such cases, clean the autosave directory prior to the restore operation as shown in this example:
# cd / # rm -rf var/opt/SUNWldm/autosave-*
These commands restore the files and directories in the /var/opt/SUNWldm directory.
# cd / # tar -xvpf autosave.tar
Whenever you upgrade the operating system on the control domain, you must save and restore the /var/opt/SUNWldm/ldom-db.xml Logical Domains constraints database file.
If you are using the Oracle Solaris 10 Live Upgrade feature on the control domain, consider adding the following line to the /etc/lu/synclist file. This line causes the database to be copied automatically from the active boot environment to the new boot environment when you switch boot environments.
For more information about /etc/lu/synclist and synchronizing files between boot environments, refer to Synchronizing Files Between Boot Environments in Oracle Solaris 10 8/11 Installation Guide: Live Upgrade and Upgrade Planning .
