|
* ---------------
|
|
*
|
|
* 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.
