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

Use zonecfg with the delete subcommand to delete a zone configuration from the system.

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

  1. Become root or assume an equivalent role.
  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
      Are you sure you want to delete zone a-zone (y/[n])? y
