  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.
  29  * 11-18-11  02.00.07  Incorporating additions for MPI v2.5.
  30  * 02-06-12  02.00.08  Added MPI2_RAID_ACTION_PHYSDISK_HIDDEN.
  31  * 07-26-12  02.00.09  Added ElapsedSeconds field to MPI2_RAID_VOL_INDICATOR.
  32  *                     Added MPI2_RAID_VOL_FLAGS_ELAPSED_SECONDS_VALID define.
