+ * Creation Date:  April 26, 2007
+ *
+ *   mpi2_raid.h Version:  02.00.08
+ *
+ * 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.
