Using the zonecfg Command to Modify a Zone Configuration

Using the `zonecfg` Command to Modify a Zone Configuration

You can also use the zonecfg command to do the following:

You can select a resource type and modify the specification for that resource.

You must be the global administrator in the global zone or a user with the correct rights profile to perform this procedure.

Become an administrator.
Select the zone to be modified, my-zone in this procedure.
```
global# zonecfg -z my-zone
```
Select the resource type to be changed, for example, a resource control.
```
zonecfg:my-zone> select rctl name=zone.cpu-shares
```

Remove the current value.

zonecfg:my-zone:rctl> remove value (priv=privileged,limit=20,action=none)

Add the new value.

zonecfg:my-zone:rctl> add value (priv=privileged,limit=10,action=none)

End the revised rctl specification.
```
zonecfg:my-zone:rctl> end
```
Commit the zone configuration for the zone.
```
zonecfg:my-zone> commit
```
Exit the zonecfg command.
```
zonecfg:my-zone> exit
```
Note that even if you did not explicitly type commit at the prompt, a commit is automatically attempted when you type exit or an EOF occurs.
Committed changes made through zonecfg take effect the next time the zone is booted.

Use this procedure to reset a standalone property.

Become an administrator.
Select the zone to be modified, my-zone in this procedure.
```
global# zonecfg -z my-zone
```
Clear the property to be changed, the existing pool association in this procedure.
```
zonecfg:my-zone> clear pool
```
Commit the zone configuration for the zone.
```
zonecfg:my-zone> commit
```
Exit the zonecfg command.
```
zonecfg:my-zone> exit
```
Note that even if you did not explicitly type commit at the prompt, a commit is automatically attempted when you type exit or an EOF occurs.
Committed changes made through zonecfg take effect the next time the zone is booted.

This procedure can be used to rename zones that are in either the configured state or the installed state.

You must be the global administrator in the global zone or a user with the correct rights profile to perform this procedure.

Become an administrator.
Select the zone to be renamed, my-zone in this procedure.
```
global# zonecfg -z my-zone
```
Change the name of the zone, for example, to newzone.
```
zonecfg:my-zone> set zonename=newzone
```
Commit the change.
```
zonecfg:newzone> commit
```
Exit the zonecfg command.
```
zonecfg:newzone> exit
