Example 2 with VVSetVolumeClone

use of com.emc.storageos.hp3par.command.VVSetCloneList.VVSetVolumeClone in project coprhd-controller by CoprHD.

the class HP3PARCGHelper method createConsistencyGroupClone.

/**
 * Creating physical copy for VVset or CG clone Rest API expects created
 * VVset with its corresponding volumes types for clone destination So,
 * There are many ways for implementation
 *
 * 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
 *
 * option 2 is implemented, need to handle negative / error cases of option
 * 3
