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  *  02-06-12  02.00.08  Added MPI2_RAID_ACTION_PHYSDISK_HIDDEN.
