use of com.emc.storageos.svcs.errorhandling.resources.APIException in project coprhd-controller by CoprHD.

the class RPBlockServiceApiImpl method prepareRecommendedVolumes.

/**
 * Prepare Recommended Volumes for Protected scenarios only.
 *
 * This method is responsible for acting the same as the unprotected "prepareRecommendedVolumes" call,
 * however it needs to create multiple volumes per single volume requests in order to generate protection.
 *
 * Those most typical scenario is, that for any one volume requested in a CRR configuration, we create:
 * 1. One Source Volume
 * 2. One Source Journal Volume (minimum 10GB, otherwise 2.5X source size)
 * 3. One Target Volume on protection varray
 * 4. One Target Journal Volume on protection varray
 *
 * In a CLR configuration, there are additional volumes created for the Local Target and Local Target Journal.
 *
 * This method will assemble a ProtectionSet object in Cassandra that will describe the Protection that
 * will be created on the Protection System.
 *
 * When other protection mechanisms come on board, the RP-ness of this method will need to be pulled out.
 *

/**
 * Allows the caller to change the virtual pool for the volume identified in
 * the request. Currently, the only virtual pool changes that are supported
 * are as follows:
 *
 * Change the virtual pool for a VPLEX virtual volume. This virtual pool
 * change would allow the caller to change the types of drives, for example,
 * used for the backend volume(s) that are used by the virtual volume.
 *
 * Change the virtual pool for a VPLEX virtual volume, such that a local
 * VPLEX virtual volumes becomes a distributed VPLEX virtual volume.
 *
 * Change the virtual pool of a VMAX or VNX Block volume to make the volume
 * a local or distributed VPLEX virtual volume. Essentially, the volume
 * becomes the backend volume for a VPLEX virtual volume. Similar to
 * creating a virtual volume, but instead of creating a new backend volume,
 * using the volume identified in the request. The VMAX or VNX volume cannot
 * currently be exported for this change.
 *
 * Change the virtual pool of a VMAX or VNX Block volume to make the volume
 * a RecoverPoint protected volume. The volume must be able to stay put, and
 * ViPR will build a protection around it.
 *
 * Change the virtual pool of a VMAX or VNX Block volume to allow native
 * continuous copies to be created for it.
 *
 * Change the virtual pool of a volume to increase the export path parameter max_paths.
 * The number of paths will be upgraded if possible for all Export Groups / Export Masks
 * containing this volume. If the volume is not currently exported, max_paths can be
 * decreased or paths_per_initiator can be changed. Note that changing max_paths does
 * not have any effect on the export of BlockSnapshots that were created from this volume.
 *
 * Change the virtual pool of a VMAX and VNX volume to allow change of Auto-tiering policy
 * associated with it.
