Background: The supported mechanism to deploy zones within a Data Base LDOM on SuperCluster is with the tools provided from the system/platform/supercluster/ssc-exavm package. This package provides two main scripts that are use in the creation of the zone:

1) /opt/oracle.supercluster/zonetools/exavmgen/exavmgen is used to take a dat file combined with the output of Oracle Exadata Deployment Assistant (OEDA) and generate the required xml definitions for the creation of the zone.

For example something similar to the following syntax may have been used to generate the xml:
exavmgen -nodes dbnode1 dbnode2 -datfile dbnode1_zone1.dat dbnode2_zone1 -zipfile

The output of the this script will place the xml file in the following location:

2) /opt/oracle.supercluster/zonetools/ssc_exavm/ssc_exavm is the script used to actually create the zone on each host.

For example a command similar to the following may have been used to start the creation of the zone. Optionally the -createvm may have been passed to the proceeding exavmgen script to automatically call ssc_exavm
ssc_exavm -create -vmDataDir /zoneData/ExaVmConfigDir/{CLUSTER_NAME}/vmgen/tmp/xmldata/

3) /opt/oracle.supercluster/zonetools/ssc_exavm/ssc_exavm -template may have been run to create a template zone. This will be noted in `zoneadm list -cv` as a zone with "_T" proceeding the zone name. If a template zone was created, the ssc_exavm command will use `zoneadm -z zonename clone` as opposed to `zoneadm -z zonename install`

NOTE: With the introduction of JOC Ocmd-13.326 version of OneCommand, OneCommand itself will perform the function of exavmgen. In this case the xml file with reside in /opt/oracle.supercluster/zonetools/ssc_exavm/{ZONE_NAME}-zoneConfig.xml
