CLUSPROP_DISK_SIGNATURE

The CLUSPROP_DISK_SIGNATURE structure describes the signature that is stored on the disk for identifying it to the operating system. The CLUSPROP_DISK_SIGNATURE is used in a value list and consists of:

• A CLUSPROP_VALUE structure describing the format, type, and length of the numeric data.
• A DWORD value.

The CLUSPROP_DISK_SIGNATURE structure is defined in CLUSAPI.H.

typedef struct _CLUSPROP_DISK_SIGNATURE {
    CLUSPROP_SYNTAX           Syntax;
    DWORD                     cbLength;
    DWORD                     dw;
} CLUSPROP_DISK_NUMBER, *PCLUSPROP_DISK_NUMBER;
 

Members

Syntax

Member of the CLUSPROP_VALUE structure describing the format and type of the dw member.

cbLength

Member of the CLUSPROP_VALUE structure indicating the count of bytes in the dw structure.

dw

Numeric value that describes the disk signature.

Remarks

The CLUSPROP_DISK_SIGNATURE structure is defined as a CLUSPROP_DWORD structure, which combines numeric data with the standard value header containing format, type, and length information.

A CLUSPROP_DISK_SIGNATURE structure can be returned by ClusterResourceControl when the dwControlCode parameter is set to CLUSCTL_RESOURCE_STORAGE_GET_DISK_INFO, and by ClusterResourceTypeControl when dwControlCode is set to CLUSCTL_RESOURCE_TYPE_STORAGE_GET_AVAILABLE_DISKS.
