How to Recover From a Failure While Committing Live Zone Configuration Changes

The configuration of a running zone can change externally while a live zone configuration is being edited. When this conflict occurs, the zonecfg commit command returns an error.

Perform this procedure to correct the error by reloading the zone configuration to show the updated version and then making your edits again.

On the global zone, become an administrator.

For more information, see Using Rights Profiles to Install and Manage Zones.
Issue the reload subcommand, make the correct configuration changes, and commit the change.
This step assumes that you are still in the zonecfg session that failed to commit your temporary configuration changes.
```
zonecfg:zonename> reload
zonecfg:zonename> 
temporary-configuration-changes
zonecfg:zonename> commit
```
