  11  *  Version History
  12  *  ---------------
  13  *
  14  *  Date      Version   Description
  15  *  --------  --------  ------------------------------------------------------
  16  *  04-30-07  02.00.00  Corresponds to Fusion-MPT MPI Specification Rev A.
  17  *  08-31-07  02.00.01  Modifications to RAID Action request and reply,
  18  *                      including the Actions and ActionData.
  19  *  02-29-08  02.00.02  Added MPI2_RAID_ACTION_ADATA_DISABL_FULL_REBUILD.
  20  *  05-21-08  02.00.03  Added MPI2_RAID_VOL_CREATION_NUM_PHYSDISKS so that
  21  *                      the PhysDisk array in MPI2_RAID_VOLUME_CREATION_STRUCT
  22  *                      can be sized by the build environment.
  23  *  07-30-09  02.00.04  Added proper define for the Use Default Settings bit of
  24  *                      VolumeCreationFlags and marked the old one as obsolete.
  25  *  05-12-10  02.00.05  Added MPI2_RAID_VOL_FLAGS_OP_MDC define.
  26  *  08-24-10  02.00.06  Added MPI2_RAID_ACTION_COMPATIBILITY_CHECK along with
  27  *                      related structures and defines.
  28  *                      Added product-specific range to RAID Action values.
