Using the zonecfg Command to Revert or Remove a Zone Configuration

Use the zonecfg command described in zonecfg(1M) to revert a zone's configuration or to delete a zone configuration.

How to Revert a Zone Configuration

While configuring a zone with the zonecfg utility, use the revert subcommand to undo a resource setting made to the zone configuration.

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

1. Become root or assume an equivalent role.
2. While configuring a zone called tmp-zone, type info to view your configuration:

   zonecfg:tmp-zone> info

   The net resource segment of the configuration displays as follows:

   .
   .
   .
   fs:
           dir: /tmp
           special: swap
           type: tmpfs
   net:
           address: 192.168.0.1
           physical: eri0
   device
           match: /dev/pts/*
   .
   .
   .

3. Remove the net address:

   zonecfg:tmp-zone> remove net address=192.168.0.1

4. Verify that the net entry has been removed.

   zonecfg:tmp-zone> info

   .
   .
   .
   fs:
           dir: /tmp
           special: swap
           type: tmpfs
   device
           match: /dev/pts/*
   .
   .
   .

5. Type revert.

   zonecfg:tmp-zone> revert

6. Answer yes to the following question:

   Are you sure you want to revert (y/[n])? y

7. Verify that the net address is once again present:

   zonecfg:tmp-zone> info

   .
   .
   .
   fs:
           dir: /tmp
           special: swap
           type: tmpfs
   net:
           address: 192.168.0.1
           physical: eri0
   device
           match: /dev/pts/*
   .
   .
   .

How to Delete a Zone Configuration

2. Delete the zone configuration for the zone a-zone by using one of the following two methods:

   • Use the -F option to force the action:

     global# zonecfg -z a-zone delete -F

   • Delete the zone interactively by answering yes to the system prompt:

     global# zonecfg -z a-zone delete
