 * Version History
 * ---------------
 *
 * Date      Version   Description
 * --------  --------  ------------------------------------------------------
 * 04-30-07  02.00.00  Corresponds to Fusion-MPT MPI Specification Rev A.
 * 08-31-07  02.00.01  Modifications to RAID Action request and reply,
 *                     including the Actions and ActionData.
 * 02-29-08  02.00.02  Added MPI2_RAID_ACTION_ADATA_DISABL_FULL_REBUILD.
 * 05-21-08  02.00.03  Added MPI2_RAID_VOL_CREATION_NUM_PHYSDISKS so that
 *                     the PhysDisk array in MPI2_RAID_VOLUME_CREATION_STRUCT
 *                     can be sized by the build environment.
 * 07-30-09  02.00.04  Added proper define for the Use Default Settings bit of
 *                     VolumeCreationFlags and marked the old one as obsolete.
 * 05-12-10  02.00.05  Added MPI2_RAID_VOL_FLAGS_OP_MDC define.
 * 08-24-10  02.00.06  Added MPI2_RAID_ACTION_COMPATIBILITY_CHECK along with
 *                     related structures and defines.
 *                     Added product-specific range to RAID Action values.
 * 11-18-11  02.00.07  Incorporating additions for MPI v2.5.
 * 02-06-12  02.00.08  Added MPI2_RAID_ACTION_PHYSDISK_HIDDEN.
 * 07-26-12  02.00.09  Added ElapsedSeconds field to MPI2_RAID_VOL_INDICATOR.
 *                     Added MPI2_RAID_VOL_FLAGS_ELAPSED_SECONDS_VALID define.
 * 04-17-13  02.00.10  Added MPI25_RAID_ACTION_ADATA_ALLOW_PI.
