Migrating a Zone From a Machine That Is not Usable

A machine that hosts a native Solaris zone can become unusable. However, if the storage the zone lives on, such as a SAN, is still usable, it might still be possible to migrate the zone to a new host successfully. You can move the zonepath for the zone to the new host. In some cases, such as a SAN, the zonepath data might not actually move. The SAN might simply be re-configured so the zonepath is visible on the new host. Since the zone was not properly detached, you will have to first create the zone on the new host using the zonecfg command. Once this has been done, attach the zone on the new host. Although the new host will tell you the zone was not properly detached, the system will attempt the attach anyway.

The procedure for this task is described in steps 4 through 8 of How to Migrate A Non-Global Zone. Also see How to Move the zonepath to a New Host.
