[MS-VDS]: Virtual Disk Service (VDS) Protocol Specification

2.2.2.4.1.4 VDS_PATH_STATUSThe VDS_PATH_STATUS enumeration defines the set of status values for a path to a storagedevice.typedef enum _VDS_PATH_STATUS{VDS_MPS_UNKNOWN = 0x00000000,VDS_MPS_ONLINE = 0x00000001,VDS_MPS_FAILED = 0x00000005,VDS_MPS_STANDBY = 0x00000007} VDS_PATH_STATUS;VDS_MPS_UNKNOWN: The status of the path is unknown.VDS_MPS_ONLINE: The path is available.VDS_MPS_FAILED: The path is unavailable.VDS_MPS_STANDBY: The path is on standby; it is available but will not be used unless otherpaths fail.2.2.2.4.2 Structures2.2.2.4.2.1 VDS_WWNThe VDS_WWN structure defines a worldwide name (WWN). This structure corresponds to theHBA_WWN structure, as specified in [HBAAPI], which also defines the WWN term.typedef struct _VDS_WWN {unsigned char rguchWwn[8];} VDS_WWN;rguchWwn: An array of 8 bytes that specifies the 64-bit WWN value. The first element of thearray is the most significant byte of the WWN, and the most significant bit of that byte is themost significant bit of the WWN.2.2.2.4.2.2 VDS_HBAPORT_PROPThe VDS_HBAPORT_PROP structure defines the properties of an HBA port.typedef struct _VDS_HBAPORT_PROP {VDS_OBJECT_ID id;VDS_WWN wwnNode;VDS_WWN wwnPort;VDS_HBAPORT_TYPE type;VDS_HBAPORT_STATUS status;unsigned long ulPortSpeed;unsigned long ulSupportedPortSpeed;} VDS_HBAPORT_PROP;id: The VDS object ID of the HBA port object.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 201165 / 360
