DEVICE_DATA_SET_REPAIR_PARAMETERS structure (ntddstor.h)
The DEVICE_DATA_SET_REPAIR_PARAMETERS structure specifies the parameters of a storage spaces repair operation specified for a data set management action.
This parameter structure is used in a repair action for an IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES request. The Action member of the DEVICE_DSM_INPUT structure is set to DeviceDsmAction_Repair, and ParameterBlockOffset indicates the location of DEVICE_DATA_SET_REPAIR_PARAMETERS.
Syntax
typedef struct _DEVICE_DATA_SET_REPAIR_PARAMETERS {
ULONG NumberOfRepairCopies;
ULONG SourceCopy;
ULONG RepairCopies[ANYSIZE_ARRAY];
} DEVICE_DATA_SET_REPAIR_PARAMETERS, *PDEVICE_DATA_SET_REPAIR_PARAMETERS, DEVICE_DSM_REPAIR_PARAMETERS, *PDEVICE_DSM_REPAIR_PARAMETERS;
Members
NumberOfRepairCopies
The total number of copies to repair.
SourceCopy
The source copy number.
RepairCopies[ANYSIZE_ARRAY]
An array of copy numbers for the copies to repair.
Remarks
The ParameterBlockOffset and ParameterBlockLength members of DEVICE_DSM_INPUT are set to the location and length of the DEVICE_DATA_SET_REPAIR_PARAMETERS structure in the system buffer of the IOCTL_STORAGE_MANAGE_DATA_SET_ATTRIBUTES request.
The DataSetRangesOffset and DataSetRangesLength members of DEVICE_DSM_INPUT specify the DEVICE_DSM_RANGE structures containing the extents of the repair copies.
