Using Solaris Live Upgrade With a Zone Root on a ZFS File System

The Solaris 10 10/08 release provides the ability to install a ZFS root file system and configure a zone root on ZFS. Typically, you can create and configure a zone root on ZFS as you wish. With Solaris Live Upgrade, however, only the following configurations for a zone root on ZFS are currently supported:

• If you have a UFS root file system, all zone roots on UFS, and you are running one of the following releases:

  • Solaris 10 6/06, Solaris 10 11/06, Solaris 10 8/07, Solaris 10 5/08

  • Solaris 10 10/08

  You can migrate to a configuration in which the root file system is ZFS, all zone roots are on ZFS, and which runs the Solaris 10 10/08 release. This configuration can subsequently be patched and upgraded to run a future Solaris 10 release.

• You can install a Solaris 10 10/08 system with a ZFS root file system and then configure all zone roots on ZFS. The zone roots must be in the same pool as the global root file system. This configuration can subsequently be patched and upgraded to run a future Solaris 10 release.

For complete instructions on setting up these configurations, see Solaris Installation and Solaris Live Upgrade Requirements for ZFS Support in Solaris ZFS Administration Guide.

Review the information in this chapter before you begin your migration to a ZFS root file system or before setting up zones on a system with a ZFS root file system. Follow the recommended procedure exactly to set up zones on a system with ZFS root file system to ensure that you can use Solaris Live Upgrade on that system.
