the class HP3PARCGHelper method createConsistencyGroupClone.

/**

 *
 * 1. Customer will provide the VVSet name which already exist in Array
 * with its corresponding similar volumes for cloning
 *
 * 2. Customer will not provide any existing and matching VV set with
 * corresponding volumes for CG clone
 *
 * 3. Customer will provide VVset name which is created but volumes are not
 * matching for clone creation.

 * Create new VV Set / CG . Create new volumes similar to parent VVSet
 * volumes Use this newly created VV set for CG clone
